Making open source more inclusive
Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.
Chapter 1. Introduction to Red Hat JBoss Web Server installation
Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. Red Hat JBoss Web Server provides a fully supported implementation of the Apache Tomcat Servlet container and the Tomcat native library.
If you need clustering or session replication support for Java applications, use Red Hat JBoss Enterprise Application Platform (JBoss EAP).
1.1. JBoss Web Server components
JBoss Web Server includes components such as the Apache Tomcat Servlet container, Tomcat native library, Tomcat vault, mod_cluster
library, Apache Portable Runtime (APR), and OpenSSL.
- Apache Tomcat
- Apache Tomcat is a servlet container in accordance with the Java Servlet Specification. JBoss Web Server 6.x contains Apache Tomcat 10.1.
- Tomcat native library
- The Tomcat native library improves Tomcat scalability, performance, and integration with native server technologies.
- Tomcat vault
- Tomcat vault is an extension for JBoss Web Server that is used for securely storing passwords and other sensitive information used by a JBoss Web Server.
- Mod_cluster
-
The
mod_cluster
library enables communication between Apache Tomcat and themod_proxy_cluster
module of the Apache HTTP Server. Themod_cluster
library enables you to use the Apache HTTP Server as a load balancer for JBoss Web Server. For more information about configuringmod_cluster
, or for information about installing and configuring alternative load balancers such asmod_jk
andmod_proxy
, see the HTTP Connectors and Load Balancing Guide. - Apache Portable Runtime
- The Apache Portable Runtime (APR) provides an OpenSSL-based TLS implementation for the HTTP connectors.
- OpenSSL
- OpenSSL is a software library that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. OpenSSL includes a basic cryptographic library.
For a full list of components that Red Hat JBoss Web Server supports, see the JBoss Web Server Component Details page.
1.2. Differences between the Apache Tomcat distributions that Red Hat provides
Both Red Hat JBoss Web Server and Red Hat Enterprise Linux (RHEL) provide separate distributions of Apache Tomcat. However, JBoss Web Server offers distinct benefits compared to the RHEL distribution of Apache Tomcat by including an integrated and certified set of additional components and features. JBoss Web Server also provides more frequent software and security updates.
RHEL provides a distribution of Apache Tomcat on RHEL 7, RHEL 8.8 or later, and RHEL 9.2 or later only.
For RHEL 8.0 through 8.7 and RHEL 9.0 through 9.1, the RHEL platform subscriptions do not provide a distribution of Apache Tomcat. On these operating system versions, JBoss Web Server is the only Apache Tomcat distribution that Red Hat provides, which is available as part of the Middleware Runtimes subscription.
Apache Tomcat versions
Consider the following version information for the Apache Tomcat distributions that are available with JBoss Web Server and RHEL:
- Apache Tomcat versions available with RHEL
-
The RHEL 7
tomcat
package is based on the community version of Apache Tomcat 7. -
The RHEL 8.x and RHEL 9.x
tomcat
package is based on the community version of Apache Tomcat 9. Thetomcat
package is available with RHEL 8.8 or later and RHEL 9.2 or later only.
-
The RHEL 7
- Apache Tomcat versions available with JBoss Web Server
- JBoss Web Server 3.1 provides a distribution of Apache Tomcat 7 and Apache Tomcat 8 together with an integrated and certified set of additional components and features. However, Red Hat no longer fully supports or maintains JBoss Web Server 3.1, which is currently in extended life cycle support (ELS) phase 2 with a planned end-of-life date of December 2028.
- JBoss Web Server 5.x provides a distribution of Apache Tomcat 9 that Red Hat fully tests and supports together with an integrated and certified set of additional components and features. Red Hat plans to end full support for JBoss Web Server 5.x on July 31, 2024. Red Hat will provide maintenance support until July 31, 2025 followed by extended life cycle support (ELS) phase 1 with a planned end-of-life date of July 2027.
- JBoss Web Server 6.x provides a distribution of Apache Tomcat 10.1 that Red Hat fully tests and supports together with an integrated and certified set of additional components and features.
For more information about product life cycle phases and available support levels, see Life Cycle Phases. For more information about Apache Tomcat versions, see Apache Tomcat versions supported by Red Hat.
Red Hat does not provide support for community releases of Apache Tomcat.
Differences between JBoss Web Server and RHEL distributions of Apache Tomcat
Consider the following differences between JBoss Web Server and the RHEL distribution of Apache Tomcat:
JBoss Web Server | RHEL distribution of Apache Tomcat |
---|---|
Supports installation from archive files or RPM packages on RHEL versions 8 and 9. Note Red Hat does not provide a distribution of JBoss Web Server 6.x on RHEL 7. | Supports installation from RPM packages only on RHEL 7, RHEL 8.8, and RHEL 9.2 or later. |

2.4. Managing JBoss Web Server by using systemd
when installed from an archive file
When you install JBoss Web Server from an archive file on Red Hat Enterprise Linux, you can use a system daemon to perform management tasks. Using the JBoss Web Server with a system daemon provides a method of starting the JBoss Web Server services at system startup. The system daemon also provides start, stop and status check functions.
On Red Hat Enterprise Linux versions 8 and 9, the default system daemon is systemd
.
Prerequisites
Procedure
To determine which system daemon is running, enter the following command:
$ ps -p 1 -o comm=
If
systemd
is running, the following output is displayed:systemd
To set up the JBoss Web Server for
systemd
, run the.postinstall.systemd
script as the root user:# cd JWS_HOME/tomcat # sh .postinstall.systemd
To control the JBoss Web Server with
systemd
, you can perform any of the following steps as the root user:To enable the JBoss Web Server services to start at system startup by using
systemd

2.5. JBoss Web Server configuration for managing archive installations from the command line
When you install JBoss Web Server from an archive file on Red Hat Enterprise Linux, you can start and stop JBoss Web Server directly from the command line. Before you can run JBoss Web Server from the command line, you must perform the following series of configuration tasks:
-
Set the
JAVA_HOME
environment variable for Tomcat. -
Create a
tomcat
user and its parent group. -
Grant the
tomcat
user access to JBoss Web Server.
When you manage JBoss Web Server by using a system daemon rather than from the command line, the .postinstall.systemd
script performs these configuration steps automatically.
2.5.1. Setting the JAVA_HOME environment variable for Apache Tomcat
Before you run JBoss Web Server from the command line for the first time, you must set the JAVA_HOME
environment variable for Apache Tomcat.
Prerequisites
Procedure
-
On a command line, go to the
JWS_HOME/tomcat/bin
directory. -
Create a file named
setenv.sh
. In the
setenv.sh
file, enter theJAVA_HOME
path definition.For example:
export JAVA_HOME=/usr/lib/jvm/jre-11-openjdk.x86_64
2.5.2. Creating a Tomcat user and group
Before you run JBoss Web Server from the command line for the first time, you must create a tomcat
user account and user group to enable simple and secure user management. On Red Hat Enterprise Linux, the user identifer (UID) for the tomcat
user and the group identifier (GID) for the tomcat
group both have a reserved value of 53
.
You must perform all steps in this procedure as the root user.
Prerequisites
Procedure
-
On a command line, go to the
JWS_HOME
directory. Create the
tomcat
user group:# groupadd -g 53 -r tomcat
Create the
tomcat
user in thetomcat
user group:# useradd -c "tomcat" -u 53 -g tomcat -s /sbin/nologin -r tomcat
The preceding commands set both the UID and the GID to 53
. If you subsequently want to change the UID and GID values, see Changing the UID and GID for the tomcat
user and group.
2.5.3. Granting the Tomcat user access to JBoss Web Server
Before you run JBoss Web Server from the command line for the first time, you must grant the tomcat
user access to JBoss Web Server by assigning ownership of the Tomcat directories to the tomcat
user.
You must perform all steps in this procedure as the root user.
Prerequisites
Procedure
-
Go to the
JWS_HOME
directory. Assign ownership of the Tomcat directories to the
tomcat
user:# chown -R tomcat:tomcat tomcat/
Ensure that the
tomcat
user has execute permissions for all parent directories:# chmod -R u+X tomcat/
Verification
Verify that the
tomcat
user is the owner of the directory:# ls -l
2.6. Starting JBoss Web Server from the command line when installed from an archive file
When you install JBoss Web Server from an archive file on Red Hat Enterprise Linux, you can start JBoss Web Server directly from the command line.
Prerequisites
Procedure
Enter the following command as the
tomcat
user:$ sh JWS_HOME/tomcat/bin/startup.sh
2.7. Stopping JBoss Web Server from the command line when installed from an archive file
When you install JBoss Web Server from an archive file on Red Hat Enterprise Linux, you can stop JBoss Web Server directly from the command line.
Prerequisites
Procedure
Enter the following command as the
tomcat
user:$ sh JWS_HOME/tomcat/bin/shutdown.sh
2.8. SELinux policies for JBoss Web Server
You can use Security-Enhanced Linux (SELinux) policies to define access controls for JBoss Web Server. These policies are a set of rules that determine access rights to the product.
2.8.1. SELinux policy information for jws6-tomcat
The SELinux security model is enforced by the kernel and ensures that applications have limited access to resources such as file system locations and ports. SELinux policies ensure that any errant processes that are compromised or poorly configured are restricted or prevented from running.
The jws6-tomcat-selinux
packages in your JBoss Web Server installation provide a jws6_tomcat
policy. The following table contains information about the supplied SELinux policy.
Name | Port Information | Policy Information |
---|---|---|
|
Four ports in |
The
|
Additional resources
- RHEL 8: Using SELinux
- RHEL 9: Using SELinux
2.8.2. Installing SELinux policies for a JBoss Web Server archive installation
In this release, the archive packages provide SELinux policies. The tomcat
folder of the jws-6.0.0-application-server-<platform>-<architecture>.zip
archive includes the .postinstall.selinux
file. If required, you can run the .postinstall.selinux
script.
Procedure
Install the
selinux-policy-devel
package:dnf install -y selinux-policy-devel
Run the
.postinstall.selinux
script:cd <JWS_home>/tomcat/ sh .postinstall.selinux
Add access permissions to the required ports for JBoss Web Server:
semanage port -a -t http_port_t -p tcp <port>
NoteThe JBoss Web Server has access to ports
8080
,8009
,8443
and8005
on Red Hat Enterprise Linux systems.When additional ports are required for JBoss Web Server, use the preceding
semanage
command to provide the necessary permissions, and replace<port>
with the required port.Start Tomcat:
<JWS_home>/tomcat/bin/startup.sh
Check the context of the running process expecting
jws6_tomcat
:ps -eo pid,user,label,args | grep jws6_tomcat | head -n1
Verify the contexts of the Tomcat directories. For example:
ls -lZ <JWS_home>/tomcat/logs/
By default, the SElinux policy that JBoss Web Server provides is not active and the Tomcat processes run in the unconfined_java_t
domain. This domain does not confine the processes.
If you choose not to enable the SELinux policy that is provided, you can take the following security measures:
-
Restrict file access for the
tomcat
user, so that thetomcat
user only has access to the files and directories that are necessary for the JBoss Web Server runtime. - Do not run Tomcat as the root user.
When JBoss Web Server is installed from an archive file, Red Hat does not officially support the use of network file sharing (NFS). If you want your JBoss Web Server installation to use an NFS-mounted file system, you are responsible for ensuring that SELinux policies are modified correctly to support this type of deployment.
2.9. Changing the UID and GID for the tomcat
user and group
On Red Hat Enterprise Linux, the user identifer (UID) for the tomcat
user and the group identifier (GID) for the tomcat
group both have a reserved value of 53
. Depending on your setup requirements, you can change the UID and GID for the tomcat
user and group to some other value.
To avoid SELinux conflicts, use UID and GID values that are less than 500. If SELinux is set to enforcing
mode, UID and GID values greater than 500 might cause unexpected issues.
Prerequisites
-
You have created a
tomcat
user account and group.
Procedure
-
If JBoss Web Server is already running, stop JBoss Web Server as the
tomcat
user. For more information, see Stopping JBoss Web Server from the command line when installed from an archive file. To view the current UID and GID for the
tomcat
user and group, enter the following command as the root user:id tomcat
The preceding command displays the user account and group details. For example:
uid=53(tomcat) gid=53(tomcat) groups=53(tomcat)
To assign a new GID to the
tomcat
group, enter the following command as the root user:groupmod -g <new_gid> tomcat
For example:
groupmod -g 410 tomcat
To assign a new UID to the
tomcat
user, enter the following command as the root user:usermod -u <new_uid> -g <new_gid> tomcat
For example:
usermod -u 401 -g 410 tomcat
To reassign file and directory permissions to the new UID, enter the following command as the root user:
# find / -not -path '/proc*' -uid <original_uid> | perl -e '$ug = @ARGV[0]; foreach $fn (<STDIN>) { chomp($fn);$m = (stat($fn))[2];chown($ug,-1,$fn);chmod($m,$fn)}' <new_uid>
In the preceding command, replace <original_uid> with the old UID and replace <new_uid> with the new UID. For example, to reassign file and directory permissions from UID
53
to UID401
, enter the following command:# find / -not -path '/proc*' -uid 53 | perl -e '$ug = @ARGV[0]; foreach $fn (<STDIN>) { chomp($fn);$m = (stat($fn))[2];chown($ug,-1,$fn);chmod($m,$fn)}' 401
To reassign file and directory permissions to the new GID, enter the following command as the root user:
# find / -not -path '/proc*' -gid <original_gid> | perl -e '$ug = @ARGV[0]; foreach $fn (<STDIN>) { chomp($fn);$m = (stat($fn))[2];chown(-1,$ug,$fn);chmod($m,$fn)}' <new_gid>
In the preceding command, replace <original_gid> with the old GID and replace <new_gid> with the new GID. For example, to reassign file and directory permissions from GID
53
to GID410
, enter the following command:# find / -not -path '/proc*' -gid 53 | perl -e '$ug = @ARGV[0]; foreach $fn (<STDIN>) { chomp($fn);$m = (stat($fn))[2];chown(-1,$ug,$fn);chmod($m,$fn)}' 410

Open the Command Prompt as an administrator and enter the following command:
net start tomcat10
-
Click Start > Administrative Tools > Services, right-click the
Tomcat10
service, and click Start.
Some third-party applications add libraries to the system directory in Windows. These third-party libraries take precedence over Tomcat libraries during lookups. If the third-party libraries have the same name as the Tomcat native libraries, the system loads the third-party libraries rather than the libraries that are distributed with JBoss Web Server. In this situation, Tomcat might not start successfully, and Tomcat does not log any error messages in the Windows Event Log or the Tomcat log files.
If this behavior occurs, you can take the following steps:
-
To see errors, run the
catalina.bat run
command. -
Inspect the contents of the
C:\windows\System32\
directory and the otherPATH
directories. -
Ensure that dynamic link libraries (DLLs) do not conflict with the JBoss Web Server libraries. In particular, look for the
libeay32.dll
,ssleay32.dll
, andlibssl32.dll
libraries.
4.6. Stopping JBoss Web Server on Microsoft Windows

Tomcat10
service, and click Stop.
Chapter 5. Enabling HTTP/2 for the Red Hat JBoss Web Server
The Hypertext Transfer Protocols (HTTP) are standard methods of transmitting data between applications, such as servers and browsers, over the internet. JBoss Web Server supports the use of HTTP/2 for encrypted connections that are using Transport Layer Security (TLS), which is indicated by the h2
keyword when enabled.
HTTP/2 improves on HTTP/1.1 by providing the following enhancements:
- Header compression omits implied information to reduce the size of the header that is transmitted.
- Multiple requests and responses over a single connection use binary framing rather than textual framing to break down response messages.
JBoss Web Server does not support the use of HTTP/2 for unencrypted connections that are using the Transmission Control Protocol (TCP), which is indicated by the h2c
keyword when enabled.
5.1. Prerequisites
- You have root user access on Red Hat Enterprise Linux.
- You have installed Red Hat JBoss Web Server 5.0 or later.
You have installed the
openssl
andapr
packages that are provided with Red Hat Enterprise Linux. For more information about installing theopenssl
andapr
packages, see Red Hat Enterprise Linux package requirements.NoteThese operating system native libraries are also provided by
jws-6.0.0-application-server-<platform>-<architecture>.zip
where available.If you want to run JSSE+OpenSSL or APR on Red Hat Enterprise Linux version 8 or 9, you must use Tomcat-Native to ensure successful operation. Tomcat-Native is located in the native archive directory.
You have configured a connector that supports the HTTP/2 protocol with SSL enabled. For JBoss Web Server 6.0, the following connectors support the HTTP/2 protocol:
- The NIO connector with JSSE + OpenSSL (JSSE)
- The NIO2 connector with JSSE + OpenSSL (JSSE)
5.2. Enabling HTTP/2 for a connector
In the server.xml
file, the upgrade protocol in the connector definition is already set to HTTP/2 by default.
Procedure
-
Open the
JWS_HOME/tomcat/conf/server.xml
configuration file. In the connector definition, ensure that the
UpgradeProtocol
class name is set toorg.apache.coyote.http2.Http2Protocol
.For example:
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true" maxParameterCount="1000"> <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" /> <SSLHostConfig> <Certificate certificateKeystoreFile="conf/localhost-rsa.jks" certificateKeystorePassword="changeit" type="RSA" /> </SSLHostConfig> </Connector>
To apply any configuration updates, restart the Red Hat JBoss Web Server as the root user.
To restart JBoss Web Server on Red Hat Enterprise Linux by using
systemd
, enter the following command:# systemctl restart jws6-tomcat.service
To restart JBoss Web Server on Red Hat Enterprise Linux by using
startup.sh
, enter the following commands:# JWS_HOME/sbin/shudown.sh # JWS_HOME/sbin/startup.sh
To restart JBoss Web Server on Microsoft Windows, enter the following command:
# net restart tomcat10
5.3. Viewing JBoss Web Server logs to verify that HTTP/2 is enabled
You can view the JBoss Web Server console output log to verify that HTTP/2 is enabled.
Prerequisites
- You have enabled HTTP/2 for a connector.
Procedure
To view the console output log, enter the following command:
$ cat JWS_HOME/tomcat/logs/catalina.out | grep 'h2'
NoteIn the preceding command, replace
JWS_HOME
with the top-level directory for your JBoss Web Server installation.
Verification
If HTTP/2 is enabled, the command produces the following type of output that indicates the connector has been configured to support negotiation to
[h2]
:06-Apr-2018 04:49:26.201 INFO [main] org.apache.coyote.http11.AbstractHttp11Protocol.configureUpgradeProtocol The ["connector_name"] connector has been configured to support negotiation to [h2] via ALPN
5.4. Using the curl command to verify that HTTP/2 is enabled
You can use the curl
command-line tool to verify that HTTP/2 is enabled.
Prerequisites
- You have enabled HTTP/2 for a connector.
You are using a version of
curl
that supports HTTP/2.To check that you are using a version of
curl
that supports HTTP/2, enter the following command:$ curl -V
This command produces the following type of output:
curl 7.55.1 (x86_64-redhat-linux-gnu) ... Release-Date: 2017-08-14 Protocols: dict file ftp ftps gopher http https ... Features: AsynchDNS IDN IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz TLS-SRP HTTP2 UnixSockets HTTPS-proxy Metalink PSL
Procedure
To check that the HTTP/2 protocol is active, enter the following command:
$ curl -I http://<JBoss_Web_Server>:8080/
NoteIn the preceding example, replace <JBoss_Web_Server> with the URI of the modified connector, such as
example.com
. The port number is dependent on your configuration.
Verification
If the HTTP/2 protocol is active, the
curl
command produces the following output:HTTP/2 200
Otherwise, if the HTTP/2 protocol is inactive, the
curl
command produces the following output:HTTP/1.1 200

Chapter 6. Using a password vault with Red Hat JBoss Web Server
The JBoss Web Server password vault, which is named tomcat-vault
, is a PicketLink vault extension for Apache Tomcat. You can use the password vault to mask passwords and other sensitive strings, and to store sensitive information in an encrypted Java keystore. When you use the password vault, you can stop storing clear-text passwords in your Tomcat configuration files. Tomcat can use the password vault to search for passwords and other sensitive strings from a keystore.
For more information about using the CRYPT
feature with the password vault, see Using CRYPT.
The Federal Information Processing Standard (FIPS) 140-2 does not support the password-based encryption that is provided by tomcat-vault
. If you want to use password-based encryption on the JBoss Web Server host, you must ensure that FIPS is disabled. If you attempt to use tomcat-vault
when FIPS mode is enabled, the following error message is displayed: Security Vault can’t be used in FIPS mode
6.1. Password vault installation from an archive file
When you install JBoss Web Server from an archive file, the password vault is installed automatically when you install the jws-6.0.0-application-server.zip
file. The password vault is located in the JWS_HOME/tomcat/lib/tomcat-vault.jar
file.
6.2. Installing the password vault on RHEL by using the DNF package manager
When you install JBoss Web Server on Red Hat Enterprise Linux from RPM packages, you can use the DNF package manager to install the password vault.
Procedure
Enter the following command as the root user:
dnf install jws6-tomcat-vault
6.3. Enabling the password vault in JBoss Web Server
You can enable the password vault by adding a configuration property in the catalina.properties
file.
Prequisites
- You have installed the password vault from an archive file or by using the DNF package manager.
Procedure
- Stop Tomcat if it is already running.
-
Open the
JWS_HOME/tomcat/conf/catalina.properties
file. In the
catalina.properties
file, enter the following line:org.apache.tomcat.util.digester.PROPERTY_SOURCE=org.apache.tomcat.vault.util.PropertySourceVault
NoteIn the preceding example, replace
JWS_HOME
with the path to your JBoss Web Server installation. The paths shown in this example use a forward slash (/
) for directory separators.
6.4. Creating a Java keystore in JBoss Web Server
Before you use the password vault, you must first create a Java keystore by using the keytool -genseckey
command.
Procedure
Enter the following command:
$ keytool -genseckey \ -keystore JWS_HOME/tomcat/vault.keystore \ -alias my_vault \ -storetype jceks \ -keyalg AES \ -keysize 128 \ -storepass <vault_password> \ -keypass <vault_password> \ -validity 730
NoteIn the preceding example, replace the parameter settings with values that are appropriate for your environment.
For more information about each parameter, use the
keytool -genseckey -help
command.
The password vault does not currently support the PKCS12
keystore type. The password vault supports the JCEKS
keystore type only.
Depending on the keystore algorithm that you are using, you must specify one of the following keysize
values:
-
If you are using AES, specify
-keysize 128
. -
If you are using DES, specify
-keysize 56
. -
If you are using DESede, specify
-keysize 168
.
6.5. Password vault initialization for Apache Tomcat
You can use the tomcat-vault.sh
script to initialize the password vault for Apache Tomcat. The tomcat-vault.sh
script supports either of the following mechanisms to initialize the password vault:
Depending on how you installed the password vault, the location of the tomcat-vault
script varies:
-
If you installed the password vault from an archive file, the
tomcat-vault.sh
script is located in theJWS_HOME/tomcat/bin
directory. -
If you installed the password vault by using the DNF package manager, the
tomcat-vault.sh
script is located in the/opt/rh/jws6/root/usr/bin
directory.
6.5.1. Initializing password vault for Apache Tomcat interactively
You can initialize the password vault for Tomcat interactively. In this situation, the tomcat-vault.sh
script prompts you to enter values while the script is running.
Procedure
Go to the directory that contains the
tomcat-vault.sh
script:-
If you installed the password vault from an archive file, go to the
JWS_HOME/tomcat/bin
directory. -
If you installed the password vault from an RPM package, go to the
/opt/rh/jws6/root/usr/bin
directory.
-
If you installed the password vault from an archive file, go to the
Run the
tomcat-vault.sh
script:$ ./tomcat-vault.sh

In the preceding example, replace the specified settings with values that are appropriate for your environment.
- Note the output for the Tomcat properties file. You need this information when configuring Tomcat to use the password vault.
6.5.2. Initializing password vault for Apache Tomcat by using a noninteractive setup
You can initialize the password vault for Tomcat by using a noninteractive setup. In this situation, you must provide the required input as arguments to the tomcat-vault.sh
script when you run the script.
Procedure
Go to the directory that contains the
tomcat-vault.sh
script:-
If you installed the password vault from an archive file, go to the
JWS_HOME/tomcat/bin
directory. -
If you installed the password vault from an RPM package, go to the
/opt/rh/jws6/root/usr/bin
directory.
-
If you installed the password vault from an archive file, go to the
Run the
tomcat-vault.sh
script and provide the required arguments:For example:
$ ./tomcat-vault.sh \ --keystore JWS_HOME/tomcat/vault.keystore \ --keystore-password <vault_password> \ --alias my_vault \ --enc-dir JWS_HOME/tomcat/ \ --iteration 120 \ --salt 1234abcd \ --generate-config JWS_HOME/tomcat/conf/vault.properties
In the preceding example, replace the specified settings with values that are appropriate for your environment.
When you specify the -g, --generate-config
option, the tomcat-vault.sh
script also creates a vault.properties
file that contains the specified properties.
6.6. Configuring Tomcat to use the password vault
You can configure Apache Tomcat to use the password vault by updating configuration settings in the vault.properties
file.
Prerequisites
Procedure
-
Go to the
JWS_HOME/tomcat/conf/
directory. -
Create a file named
vault.properties
. In the
vault.properties
file, enter the vault configuration properties that you specified when you initialized the password vault for Tomcat.For example:
KEYSTORE_URL=JWS_HOME/tomcat/vault.keystore KEYSTORE_PASSWORD=MASK-3CuP21KMHn7G6iH/A3YpM/ KEYSTORE_ALIAS=my_vault SALT=1234abcd ITERATION_COUNT=120 ENC_FILE_DIR=JWS_HOME/tomcat/
The preceding example is based on the example vault settings in Initializing password vault for Apache Tomcat interactively.
For the KEYSTORE_PASSWORD
setting, ensure that you use the masked value that was generated when you initialized the password vault.
6.7. External password vault configuration
You can store the vault.properties
file for the password vault outside of the JWS_HOME/tomcat/conf/
directory. If you have already set a CATALINA_BASE/conf/
directory, you can store the vault.properties
file in the CATALINA_BASE/conf/
directory.
For more information about setting the CATALINA_BASE
directory, see the "Advanced Configuration - Multiple Tomcat Instances" section in Running The Apache Tomcat 10.1 Servlet/JSP Container on the Apache Tomcat website.
The default location for CATALINA_BASE
is JWS_HOME/tomcat/
. This is also known as the CATALINA_HOME
directory.
Additional Resources

- Running The Apache Tomcat 10.1 Servlet/JSP Container: "Advanced Configuration - Multiple Tomcat Instances"
6.8. Storing a sensitive string in the password vault
You can use the tomcat-vault.sh
script to store sensitive strings in the password vault. You can run the tomcat-vault.sh
script interactively or in a noninteractive mode.
When you add a sensitive string to the password vault, you must specify a name for the string. In this situation, the name of the string is called an attribute name
, and the string itself is called a secured attribute
.
Procedure
Go to the directory that contains the
tomcat-vault.sh
script:-
If you installed the password vault from an archive file, go to the
JWS_HOME/tomcat/bin
directory. -
If you installed the password vault from an RPM package, go to the
/opt/rh/jws6/root/usr/bin
directory.
-
If you installed the password vault from an archive file, go to the
To use the
tomcat-vault.sh
script in noninteractive mode, enter the following command:$ ./tomcat-vault.sh \ --keystore JWS_HOME/tomcat/vault.keystore \ --keystore-password <vault_password> \ --alias my_vault \ --enc-dir JWS_HOME/tomcat \ --iteration 120 \ --salt 1234abcd \ --vault-block my_block \ --attribute manager_password \ --sec-attr P@SSW0#D
The preceding example is based on the example vault settings in Initializing password vault for Apache Tomcat interactively. The preceding example stores the sensitive string, P@SSW0#D
, with the attribute name, manager_password
.
When you run the tomcat-vault.sh
script, you can optionally specify a vault block to store the password in. If you do not specify a block, the tomcat-vault.sh
script creates a block automatically. The preceding example specifies a vault block named my_block
.
6.9. Using a stored sensitive string in your Tomcat configuration
When you store a sensitive string in the password vault, you can refer to the attribute name rather than specify the actual string in your configuration files. By replacing a secured string with the attribute name for the string, you can ensure that the Tomcat configuration file contains only a reference to the password. In this situation, the actual password is stored in the password vault only.
Procedure
- Open the Tomcat configuration file that contains the sensitive string.
Replace the sensitive string with the attribute name for the string, and ensure that you enter the attribute name in the following format:
${VAULT::block_name::attribute_name::}
For example:
Consider the following example file entry for the secured string,
P@SSW0#D
:<user username="manager" password=*"P@SSW0#D"* roles="manager-gui"/>
If the secured string,
P@SSW0#D
, has the attribute name,manager_password
, replace the secured string with the following value:<user username="manager" password=*"${VAULT::my_block::manager_password::}"* roles="manager-gui"/>
The preceding example is based on the example settings in Storing a sensitive string in the password vault. The preceding example replaces a sensitive string, P@SSW0#D
, with an attribute name, manager_password
, that is in a block called, my_block
.
Chapter 7. Configuring the SSI filter
You can configure filter-based Server Side Includes (SSI) support for JBoss Web Server to enable dynamic generation of content in existing HTML pages.
SSI directives do not work if you try to configure the SSI filter as in previous versions.
Procedure
-
Open the
conf/web.xml
file. In the
web.xml
file, uncomment the following block:<mime-mapping> <extension>shtml</extension> <mime-type>text/x-server-parsed-html</mime-type> </mime-mapping>
Chapter 8. Configuring FIPS for Red Hat JBoss Web Server
When JBoss Web Server is installed on a Red Hat Enterprise Linux 8 host, you can configure JBoss Web Server to be compliant with Federal Information Processing Standards (FIPS). When you enable FIPS on the Red Hat Enterprise Linux host, this allows JBoss Web Server to operate in FIPS mode automatically.
FIPS does not support the password-based encryption functionality that is provided by the tomcat-vault
component of JBoss Web Server. If you want to use password-based encryption on the JBoss Web Server host, you must ensure that FIPS is disabled. For more information about password-based encryption and tomcat-vault
, see Vault for Red Hat JBoss Web Server.
8.1. Introduction to FIPS
The Federal Information Processing Standards (FIPS) provide guidelines and requirements for improving security and interoperability across computer systems and networks. The FIPS 140-2 and 140-3 series apply to cryptographic modules at both the hardware and software levels. The National Institute of Standards and Technology in the United States implements a cryptographic module validation program with searchable lists of both in-process and approved cryptographic modules.
Red Hat Enterprise Linux provides an integrated framework to enable FIPS 140-2 compliance on a system-wide basis. When operating under FIPS mode, software packages using cryptographic libraries are self-configured according to the global policy.

8.2. Configuring FIPS for JBoss Web Server on RHEL 8
You can enable FIPS compliance on the Red Hat Enterprise Linux 8 host during system installation. Alternatively, you can switch your system to FIPS mode after you have completed the system installation.
Procedure
To enable FIPS mode, complete either of the following steps:
- If you want to enable FIPS during system installation, follow the instructions in Security Hardening: Installing the system with FIPS mode enabled.
- If you want to switch to FIPS mode after system installation, follow the instructions in Security Hardening: Switching the system to FIPS mode.
Verification
Enter the following command:
fips-mode-setup --check
If FIPS is enabled, this prints the following output:
FIPS mode is enabled.
Appendix A. Java IPv4 and IPv6 properties
You can use Java properties to configure IPv4 and IPv6 addresses. You can subsequently export these properties to Tomcat and use address values to specify Tomcat bindings.
A.1. Overview of Java IPv4 and IPv6 properties
Java provides two properties that you can use to configure IPv4 and IPv6 addresses:
- java.net.preferIPv4Stack (default: false)
-
If IPv6 is available, the underlying native socket is an IPv6 socket by default. This socket enables applications to connect and accept connections from IPv4 and IPv6 hosts. If applications use IPv4 sockets only, set this property to
true
. However, applications that are using IPv4 sockets only cannot communicate with IPv6-only hosts. - java.net.preferIPv6Addresses (default: false)
-
If a host has both IPv4 and IPv6 addresses, and IPv6 is available, the default behavior is to use IPv4 addresses over IPv6. This allows backward compatibility. If applications depend on an IPv4 address representation, such as 192.168.1.1, set this property to
true
to change the preference, and use IPv6 addresses over IPv4 where possible.
A.2. Exporting Java IPv4 and IPv6 properties to Tomcat
You can export Java IPv4 and IPv6 properties to Tomcat by setting CATALINA_OPTS
in the JWS_HOME/tomcat/bin/setenv.*
file. On Red Hat Enterprise Linux, the setenv
file has a .sh
extension. On Microsoft Windows, the setenv
file has a .bat
extension.
Procedure
If the
JWS_HOME/tomcat/bin/setenv.*
file does not exist, create the file.NoteIf you are using Red Hat Enterprise Linux, create a
setenv.sh
file. If you are using Microsoft Windows, create asetenv.bat
file.To export Java IPv4 and IPv6 properties to Tomcat, perform either of the following steps:
If you are using Red Hat Enterprise Linux, enter the following command:
export "CATALINA_OPTS=-Djava.net.preferIPv4Stack=YOUR_VALUE -Djava.net.preferIPv6Addresses=YOUR_VALUE"
If you are using Microsoft Windows, enter the following command:
set "CATALINA_OPTS=-Djava.net.preferIPv4Stack=YOUR_VALUE -Djava.net.preferIPv6Addresses=YOUR_VALUE"
A.3. Configuring Tomcat bindings
You can configure Tomcat bindings in the JWS_HOME/tomcat/conf/server.xml
file by specifying the IPv6 address.
Procedure
-
Open the
JWS_HOME/tomcat/conf/server.xml
file. To specify the Tomcat binding address, enter the following details:
<Server ... address="TOMCAT_BINDING_ADDRESS">
To specify the HTTP connector address, enter the following details:
<Connector protocol="HTTP/1.1" ... address="HTTP_CONNECTOR_ADDRESS">
To specify the AJP connector address, enter the following details:
<Connector protocol="AJP/1.3" ... address="AJP_CONNECTOR_ADDRESS">
Ensure that you replace TOMCAT_BINDING_ADDRESS
, HTTP_CONNECTOR_ADDRESS
, and AJP_CONNECTOR_ADDRESS
with the correct IPv6 address.
