Abstract

This chapter explains how to install the Apache ActiveMQ resource adapter into JBoss EAP and how to integrate ActiveMQ messaging into your applications, taking the helloworld-mdb demonstration as an example.

1.1. Supported Web Server Platforms
リンクのコピー

Overview
リンクのコピー

The following Web server platforms are supported by JBoss A-MQ 6.3:

JBoss Enterprise Application Platform (JBoss EAP)

Supported product versions
リンクのコピー

To see which versions of JBoss EAP are supported with JBoss A-MQ 6.3, please consult the Red Hat JBoss A-MQ Supported Configurations page.

Note

AMQP 1.0 is not a supported protocol for the JBoss A-MQ JCA connector (Apache ActiveMQ resource adapter). OpenWire is the only wire protocol supported by the JCA connector / resource adapter.

1.2. Install the ActiveMQ Resource Adapter
リンクのコピー

Overview
リンクのコピー

This section describes how to find, install, and configure the ActiveMQ resource adapter into a standalone instance of the JBoss EAP.

A resource adapter is a kind of plug-in for a Java EE container. The Java EE standard defines the resource adapter framework, which makes it possible to expand the core Java EE container, adding new features and functionality. By installing the ActiveMQ resource adapter, you make it possible for message driven beans and servlets to communicate through an external JBoss A-MQ broker instance. The JBoss A-MQ broker can thus be used as the underlying messaging system in the container.

Note

Running an embedded ActiveMQ broker in JBoss EAP is not supported. The use of the resource adapter is restricted to connect to external broker instances only.

Resource adapter location

You can find the ActiveMQ resource adapter archive file, activemq-rar-5.11.0.redhat-630187.rar, at either of the following locations:

In the following Zip archive file:
```
InstallDir/extras/apache-activemq-5.11.0.redhat-630187-bin.zip
```
```
InstallDir/extras/apache-activemq-5.11.0.redhat-630187-bin.zip
```
Copy to Clipboard Toggle word wrap
After expanding the archive, the resource adapter file can be found in the following sub-directory:
```
apache-activemq-5.11.0.redhat-630187/lib/optional
```
```
apache-activemq-5.11.0.redhat-630187/lib/optional
```

Directly from the Red Hat JBoss Fuse Maven repository, at the following URL:
```
https://maven.repository.redhat.com/ga/org/apache/activemq/activemq-rar/
```
```
https://maven.repository.redhat.com/ga/org/apache/activemq/activemq-rar/
```

Download the .rar archive file from the appropriately versioned sub-directory, 5.11.0.redhat-630187.

Configuration files
リンクのコピー

The following configuration files are needed for the the ActiveMQ resource adapter (when installed in a standalone instance of the JBoss EAP):

InstallDir/standalone/configuration/standalone-full.xml: The standalone-full.xml file is the default (bare bones) configuration for the JBoss EAP container. You must edit this file to complete the installation of the ActiveMQ resource adapter.
Note
It is assumed that this file does not already configure the HornetQ messaging system (which would conflict with the ActiveMQ messaging system).

Note

JBoss EAP can be figured either as a standalone container, using standalone/configuration/standalone-full.xml, or as a managed domain, using domain/configuration/domain.xml. Throughout this section, we describe explicitly how to configure the standalone container, but it is understood that a similar approach could be used to configure a managed domain.

Steps to install the resource adapter
リンクのコピー

Perform the following steps to install the Apache ActiveMQ resource adapter into JBoss EAP (assuming that you will be running the container in standalone mode):

Extract the Apache ActiveMQ community distribution. You can find an archive of the Apache ActiveMQ distribution in the following location:
```
InstallDir/extras/apache-activemq-5.11.0.redhat-630187-bin.zip
```
```
InstallDir/extras/apache-activemq-5.11.0.redhat-630187-bin.zip
```
Copy to Clipboard Toggle word wrap
Using a suitable archive utility, extract the archive file to a convenient location on your filesystem. The root of the extracted directory tree is called apache-activemq-5.11.0.redhat-630187 by default.

The ActiveMQ resource adapter archive file can now be found under the /lib/optional sub-directory of the extracted archive.

If you need to use the ActiveMQXAConnectionFactory, you need to add extra details to the ActiveMQ resource adapter file at this point. Extract the resource adapter archive, activemq-rar-5.11.0.redhat-630187.rar to a work space. In the expanded resource adapter archive, edit META_INF/ra.xml.

Add the following entry to the adminobjects in the ra.xml file.

<adminobject>
<adminobject-interface>javax.jms.XAConnectionFactory</adminobject-interface>
<adminobject-class>org.apache.activemq.ActiveMQXAConnectionFactory</adminobject-class>
<config-property>
<config-property-name>brokerURL</config-property-name>
<config-property-type>java.lang.String</config-property-type>
</config-property>
</adminobject>

<config-property-type>java.lang.String</config-property-type>
</config-property>
</adminobject>

Zip up the resource adapter archive, and save it to a temporary location.

Rename the updated and saved resource adapter archive file. The new file name should be the same as the original name, but without the version number in the filename. For example, on a UNIX or Linux platform, you can rename the activemq-rar-5.11.0.redhat-630187.rar archive file to activemq-rar.rar
Note
Renaming the resource adapter archive in this way is not strictly necessary. But because the resource adapter file name appears in the resource adapter configuration, using a versionless filename makes it easier to upgrade the resource adapter at a later date.
Install the ActiveMQ resource adapter by copying the resource adapter archive, activemq-rar.rar, to the relevant JBoss EAP deployment directory. For example, on a UNIX or Linux platform, you could copy the resource adapter archive to a standalone JBoss Enterprise Application Platform as follows:
```
cp activemq-rar.rar EAPInstallDir/standalone/deployments/
```
```
cp activemq-rar.rar EAPInstallDir/standalone/deployments/
```

Add the requisite resource adapter configuration to the urn:jboss:domain:resource-adapters:1.1 subsystem in the JBoss EAP configuration, as follows.

Open the EAPInstallDir/standalone/configuration/standalone-full.xml file using a text editor and paste the resource-adapter element from Example 1.1, “ActiveMQ Resource Adapter Configuration in standalone-full.xml” into the urn:jboss:domain:resource-adapters:1.1 subsystem, as a child of the resource-adapters element.

If you need to use the ActiveMQXAConnectionFactory, you must also add the following information to the admin-object section of standalone-full.xml.

<admin-object class-name="org.apache.activemq.ActiveMQXAConnectionFactory" jndi-name="java:/AMQXAConnectionFactory" enabled="true" use-java-context="true" pool-name="AMQXAConnectionFactory">

If your resource adapter archive filename differs from activemq-rar.rar, you must change the content of the archive element in the preceding configuration to match the name of your archive file.

The values of the UserName and Password configuration properties must be chosen to match the credentials of a valid user in the external broker.

You might need to change the value of the ServerUrl configuration property to match the actual hostname and port exposed by the external broker.

Important

In order to ensure that JMS transactions are integrated correctly, it is essential to include the jms.rmIdFromConnectionId=true option setting on the ServerUrl configuration property and to include the <is-same-rm-override>false</is-same-rm-override> setting in the xa-pool element, as shown above.

Note

The JMS administrative objects defined in the admin-objects element do not need to be defined yet. They serve as examples to show how you can define administrative objects for the ActiveMQ resource adapter (they are used later in the message-driven bean demonstration).

Add the requisite message driven bean configuration to the urn:jboss:domain:ejb3:1.5 subsystem in the JBoss EAP configuration (where the subsystem version might vary, depending on which version of JBoss EAP you are using).

Open the EAPInstallDir/standalone/configuration/standalone-full.xml file using a text editor and paste the mdb element from Example 1.2, “Message Driven Bean Configuration in standalone-full.xml” into the urn:jboss:domain:ejb3:1.5 subsystem.

Before starting the broker, check the broker configuration to make sure that there are valid user credentials defined in the broker's InstallDir/etc/users.properties file. For example, to match the UserName and Password credentials configured in Example 1.1, “ActiveMQ Resource Adapter Configuration in standalone-full.xml”, the users.properties file should contain an entry like the following:
```
defaultUser=defaultPassword,admin
```
```
defaultUser=defaultPassword,admin

Steps to secure the resource adapter with SSL/TLS
リンクのコピー

The following steps describe how to modify the configuration of the ActiveMQ resource adapter to enable it to connect to a broker that is secured by an SSL/TLS protocol:

It is assumed that the remote broker is already configured with an SSL/TLS endpoint. For details of how to configure an OpenWire/SSL endpoint on the broker, see section "Setting Security Context for the Openwire/SSL Protocol" in "Security Guide".
Open the EAPInstallDir/standalone/configuration/standalone-full.xml file using a text editor and modify the ServerUrl property setting of the activemq-rar.rar resource adapter to point at the remote broker's OpenWire/SSL endpoint. For example:
```
<resource-adapter id="activemq-rar.rar">
    ...
    <config-property name="ServerUrl">
        ssl://localhost:61617?jms.rmIdFromConnectionId=true
    </config-property>
    ...
</resource-adapter>
```
```
<resource-adapter id="activemq-rar.rar">
    ...
    <config-property name="ServerUrl">
        ssl://localhost:61617?jms.rmIdFromConnectionId=true
    </config-property>
    ...
</resource-adapter>
```

Where the ssl scheme selects the OpenWire/SSL protocol and localhost:61617 should be customized to the host and port value of the remote broker's secure endpoint.

Specify the location and password for a trust store file, which will be used to verify the broker's certificate during the SSL/TLS handshake. Add the following property settings to the activemq-rar.rar resource adapter configuration and the org.apache.activemq.ra.ActiveMQManagedConnectionFactory connection definition configuration. Customize the settings as appropriate:

<resource-adapter id="activemq-rar.rar">
    ...
    <config-property name="TrustStore">

(Optional) If the remote broker has also been configured to require a client certificate, then it is necessary to configure the ActiveMQ resource adapter with a key store file containing a public/private key pair. In this case, you need to add the following property settings to the activemq-rar.rar resource adapter configuration and the org.apache.activemq.ra.ActiveMQManagedConnectionFactory connection definition configuration. Customize the settings as appropriate:

<resource-adapter id="activemq-rar.rar">

Note

In order for the resource adapter's certificate (the public key from the key store) to be accepted by the broker it is necessary for this certificate to be trusted by the broker. This can be achieved either by adding the resource adapter's certificate to the broker's trust store or by arranging to have the resource adapter's certificate signed by one of the certificates in the broker's trust store. For more background information on certificate signing and trust, see appendix "Managing Certificates" in "Security Guide".

Resource adapter configuration
リンクのコピー

In the configuration shown in Example 1.1, “ActiveMQ Resource Adapter Configuration in standalone-full.xml”, you use the config-property element to set resource adapter properties. The ActiveMQ resource adapter supports the following basic properties:

UserName: (Optional) Specifies the client username when connecting to the JBoss A-MQ broker (not required in this example, because the JBoss A-MQ broker configuration does not enable authentication).
Password: (Optional) Specifies the client password when connecting to the JBoss A-MQ broker (not required in this example, because the JBoss A-MQ broker configuration does not enable authentication).
ServerUrl: Specifies the URL used to connect to the JBoss A-MQ broker instance. This value must match one of the endpoints specified by a transportConnector element in the JBoss A-MQ broker configuration.
BrokerXmlConfig: (Optional) Specifies the location of an embedded broker's XML configuration file. To specify a location on the file system, use the format, xbean:file://AbsolutePath, where the path, AbsolutePath, should be specified as an absolute pathname.
Note
This property is used to run an embedded ActiveMQ broker within resource adapter. Please note that running an embedded ActiveMQ broker in JBoss EAP is currently not supported.
UseInboundSession: (Optional) Sets a flag that specifies whether outbound connections should reuse the inbound connection's session for sending messages (useful for connections going through a firewall). Defaults to false.
Clientid: (Optional) Specifies a JMS client ID, which the resource adapter uses for the connection from the JBoss EAP container.
TrustStore: Specifies the location of a trust store file, using an absolute pathname. The trust store is required, if the ActiveMQ resource adapter connects to the broker using an SSL/TLS protocol. The trust store is provided in the form of a Java keystore file, which can contain one or multiple trusted certificates.
TrustStorePassword: Specifies the password for accessing the trust store file.
KeyStore: Specifies the location of a key store file, using an absolute pathname. The key store is required, if the ActiveMQ resource adapter connects to the broker using and SSL/TLS protocol and the remote broker is also configured to require a client certificate. The key store is provided in the form of a Java keystore file, which contains a single public/private key pair.
KeyStorePassword: Specifies the password that is used both for accessing the key store file and for unencrypting the private key entry (it is a common convention to use the same password for locking the keystore file and for encrypting the private key entry).

1.3. Integrating with an ActiveMQ Failover Cluster
リンクのコピー

Overview
リンクのコピー

This section describes how to configure the ActiveMQ resource adapter to connect to an ActiveMQ failover cluster (for example, a high-availability master/slave cluster). For details about how to set up and configure such a cluster, see "Fault Tolerant Messaging".

Failover URL
リンクのコピー

To connect to a cluster of JBoss A-MQ brokers (for example, a master/slave pair of brokers), you need to configure the ServerUrl configuration property with a failover URL, which lists the available endpoints in the cluster. The general form of the failover URL you should use is as follows:

failover:(uri1,...,uriN)?maxReconnectAttempts=0&reconnectSupported=false&updateURIsSupported=false&priorityBackup=false

failover:(uri1,...,uriN)?maxReconnectAttempts=0&reconnectSupported=false&updateURIsSupported=false&priorityBackup=false

Copy to Clipboard

Toggle word wrap

Note

It is important to set the options as shown, in order to ensure a clean cutover when the master fails in a master/slave high-availability cluster. You do not want a failover client to attempt reconnection to the same endpoint. The client should always try the next URI in the failover list.

Sample scenario
リンクのコピー

Consider the scenario where a broker running on host amqhostA and a broker running on host amqhostB are configured to run as a high-availability master/slave cluster. In this scenario, the brokers expose the following TCP endpoints:

tcp://amqhostA:61616
tcp://amqhostB:61616

tcp://amqhostA:61616
tcp://amqhostB:61616

Copy to Clipboard

Toggle word wrap

To connect to this cluster, the resource adapter should be configured with the following failover URL:

failover:(tcp://amqhostA:61616,tcp://amqhostB:61616)?jms.rmIdFromConnectionId=true&maxReconnectAttempts=0&reconnectSupported=false&updateURIsSupported=false&priorityBackup=false

failover:(tcp://amqhostA:61616,tcp://amqhostB:61616)?jms.rmIdFromConnectionId=true&maxReconnectAttempts=0&reconnectSupported=false&updateURIsSupported=false&priorityBackup=false

Copy to Clipboard

Toggle word wrap

When setting the URL in an XML file, you must remember to escape the & symbol as & giving the URL:

failover:(tcp://amqhostA:61616,tcp://amqhostB:61616)?jms.rmIdFromConnectionId=true&amp;maxReconnectAttempts=0&amp;reconnectSupported=false&amp;updateURIsSupported=false&amp;priorityBackup=false

failover:(tcp://amqhostA:61616,tcp://amqhostB:61616)?jms.rmIdFromConnectionId=true&amp;maxReconnectAttempts=0&amp;reconnectSupported=false&amp;updateURIsSupported=false&amp;priorityBackup=false

Configuring the ActiveMQ resource adapter for failover
リンクのコピー

To configure the ActiveMQ resource adapter to connect to an ActiveMQ failover cluster, you must modify the following configuration settings:

Set the ServerUrl configuration property to a correctly configured failover URL,
Set the UseInboundSession configuration property to true for inbound connections (set as the direct child of the resource-adapter element), and
Set the UseInboundSession configuration property to false for the connection factories (set as the child of a connection-definition element).

Open the EAPInstallDir/standalone/configuration/standalone-full.xml file using a text editor, search for the urn:jboss:domain:resource-adapters:1.1 subsystem, and modify the ServerUrl property and the UseInboundSession property as shown in Example 1.3, “ActiveMQ Resource Adapter Configuration for Failover”. You will need to customize the value of the failover URL, as appropriate, to match the configuration of your broker cluster.

1.4. Install JBoss AS Quickstarts
リンクのコピー

Overview
リンクのコピー

The JBoss AS Quickstart examples consists of a collection of demonstrations that illustrate features of the JBoss EAP. The installation consists of the following parts:

JBoss EAP Maven repository—an offline Maven repository for JBoss EAP, which contains the dependencies required by the quickstart examples.
JBoss AS Quickstart examples—the quickstart examples themselves.

Prerequisites
リンクのコピー

To download, install, and build the JBoss AS Quickstart examples, you need the following prerequisites:

Subscription—you must have a Red Hat subscription that includes support for the JBoss EAP product (or ask Red Hat support for access as part of an evaluation).
Maven installation—you must have Apache Maven installed and the version must be 3.3 or later. You can get the latest copy of Maven from the Maven download page.
Internet access—Maven is a distributed build system, which downloads packages from the Internet on the fly, whenever they are needed during a build. Consequently, you must have access to the Internet while performing a Maven build.

JBoss AS Quickstarts download location
リンクのコピー

You can download the JBoss AS Quickstart examples from the Quickstarts download page on the Red Hat Customer Portal site. Click the following link to download the jboss-eap-6.4.0-quickstarts.zip file:

JBoss EAP 6.4.0 Quickstarts

Note

After following this link, you will be prompted to log on to the Red Hat customer access portal. If you do not have a subscription for JBoss EAP you will not be able to access this download, however.

Maven repository download location
リンクのコピー

The JBoss EAP Maven repository is required in order to run the quickstart examples.

You can download the Maven repository from the Maven Repository download page on the Red Hat Customer Portal site. Click the following link to download the jboss-eap-6.4.0-maven-repository.zip file:

Steps to install JBoss AS Quickstarts
リンクのコピー

To install the JBoss AS Quickstart examples, perform the following steps:

Download the jboss-eap-6.4.0-quickstarts.zip file from the customer portal site. Use an archive utility to unzip the downloaded file at a convenient location on your filesystem, QuickInstallDir.
Download the jboss-eap-6.4.0-maven-repository.zip file from the customer portal site. Use an archive utility to unzip the downloaded file at a convenient location on your filesystem, MvnRepoInstallDir.
Note
It is essential to download and install the Maven repository on your local machine. The quickstart examples require Maven artifacts that are not available from any public repositories online. You will not be able to build the quickstart examples unless you download, install, and configure the Maven repository.

Configure Maven to use the downloaded Maven repository by editing your local repository's settings.xml file (usually located at ~/.m2/settings.xml on Linux and UNIX systems, or at C:\Documents and Settings\Username\.m2\settings.xml on Windows). Open the settings.xml file with a text editor and add the following profiles:

Alternatively, there is a sample settings file provided at MvnRepoInstallDir/example-settings.xml in the downloaded Maven repository, which you can use as a template for defining your settings.xml file.

Replace all occurrences of file:///path/to/jboss-eap-6.4.0.GA-maven-repository in the settings.xml file with the actual location of the Maven repository on your filesystem, MvnRepoInstallDir.

Test the installation

If the project builds successfully, you should see a BUILD SUCCESS status and the generated jboss-as-helloworld-mdb.war package will be found under the QuickInstallDir/target directory.

If the project does not build successfully, make sure that you have access to the Internet and check that the Maven settings.xml file is correctly configured.

1.5. Build and Deploy the helloworld-mdb Example
リンクのコピー

Overview
リンクのコピー

In this tutorial, you will customize the helloworld-mdb quickstart example so that it works with the ActiveMQ resource adapter. You can then build and deploy the helloworld-mdb example into a standalone instance of JBoss Enterprise Application Platform (which already has an ActiveMQ resource adapter installed).

The helloworld-mdb example illustrates two kinds of integration with messaging: integration of message-driven beans; and integration of a servlet (which gets access to a JMS queue and a JMS topic using the standard JMS administered objects mechanism).

Prerequisites
リンクのコピー

The following prerequisites must be satisfied, before you can build and deploy the helloworld-mdb example:

The ActiveMQ resource adapter is installed in JBoss EAP (as described in Section 1.2, “Install the ActiveMQ Resource Adapter”), and the installation has been verified.
The JBoss EAP Maven repository and the JBoss AS Quickstart examples have been installed (as described in Section 1.4, “Install JBoss AS Quickstarts”).
You have Internet access (for the Maven build).

Customizations
リンクのコピー

The version of the helloworld-mdb demonstration provided in the quickstarts distribution is integrated with the HornetQ messaging platform by default. To refactor the demonstration so that it integrates with Apache ActiveMQ, it is necessary to customize the following aspects of the helloworld-mdb code:

Delete the HornetQ XML configuration file (located in helloworld-mdb/src/main/webapp/WEB-INF/hornetq-jms.xml).
In HelloWorldQueueMDB.java, customize the annotations on the message driven bean to integrate with the ActiveMQ resource adapter.
In HelloWorldTopicMDB.java, customize the annotations on the message driven bean to integrate with the ActiveMQ resource adapter.
Add additional Maven dependencies.

These customizations are described in more detail in the rest of this section.

Steps to build and deploy the example
リンクのコピー

To build and deploy the quickstart helloworld-mdb example, perform the following steps:

Delete the following HornetQ XML configuration file from the helloworld-mdb project:
```
helloworld-mdb/src/main/webapp/WEB-INF/hornetq-jms.xml
```
```
helloworld-mdb/src/main/webapp/WEB-INF/hornetq-jms.xml
```

Edit the annotations on the HelloWorldQueueMDB message driven bean class, so that it integrates with the ActiveMQ resource adapter (instead of HornetQ). Edit the HelloWorldQueueMDB.java file at the following location:

helloworld-mdb/src/main/java/org/jboss/as/quickstarts/mdb/HelloWorldQueueMDB.java

helloworld-mdb/src/main/java/org/jboss/as/quickstarts/mdb/HelloWorldQueueMDB.java

Open the HelloWorldQueueMDB.java file using a text editor and make the modifications highlighted in the following extract:

import org.jboss.ejb3.annotation.ResourceAdapter;
...
@MessageDriven(name = "HelloWorldQueueMDB", activationConfig = {
		@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
		@ActivationConfigProperty(propertyName = "destination", propertyValue = "HELLOWORLDMDBQueue"),
		@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge") })
@ResourceAdapter(value="activemq-rar.rar")
public class HelloWorldQueueMDB implements MessageListener {
    ...

import org.jboss.ejb3.annotation.ResourceAdapter;

@ResourceAdapter(value="activemq-rar.rar")
public class HelloWorldQueueMDB implements MessageListener {
    ...

Where the following changes are made to the code:

The @ResourceAdapter annotation explicitly associates the message driven bean with the ActiveMQ resource adapter. You must include this annotation, if you want to use the ActiveMQ resource adapter.
You need to add an import statement for the @ResourceAdapter annotation.
The value of the destination property is changed to HELLOWORLDMDBQueue, which is the physical name of the corresponding ActiveMQ queue that this message driven bean subscribes to. The physical name of the queue is the queue identifier used by the JBoss A-MQ broker.
Note
You must specify the queue's physical name here. In contrast to the case of HornetQ, the ActiveMQ messaging integration does not allow you to use a JNDI name for the destination value.

Edit the annotations on the HelloWorldTopicMDB message driven bean class, so that it integrates with the ActiveMQ resource adapter (instead of HornetQ). Edit the HelloWorldTopicMDB.java file at the following location:

helloworld-mdb/src/main/java/org/jboss/as/quickstarts/mdb/HelloWorldTopicMDB.java

helloworld-mdb/src/main/java/org/jboss/as/quickstarts/mdb/HelloWorldTopicMDB.java

Open the HelloWorldTopicMDB.java file using a text editor and make the modifications highlighted in the following extract:

		@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
		@ActivationConfigProperty(propertyName = "destination", propertyValue = "HELLOWORLDMDBTopic"),
		@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge") })
@ResourceAdapter(value="activemq-rar.rar")
public class HelloWorldTopicMDB implements MessageListener {
    ...

Add the Maven dependency for the jboss-ejb3-ext-api artifact, which is needed for the @ResourceAdapter annotation. Open the helloworld-mdb/pom.xml file using a text editor and add the following dependency element as a child of the dependencies element in the POM file:

<project ...>
    ...

The provided scope value implies there is no need to embed the jboss-ejb3-ext-api JAR file in the generated WAR, because this library is already provided by the JBoss EAP container.

Note

If you ever need to update the version of the jboss-ejb3-ext-api artifact, you can discover which version to use by drilling down to the org/jboss/ejb3/jboss-ejb3-ext-api subdirectory of the Maven repository you downloaded and installed in Section 1.4, “Install JBoss AS Quickstarts”.

Build the helloworld-mdb example as follows. Open a new command prompt, change directory to the helloworld-mdb directory, and enter the following Maven command:
```
mvn clean package
```
```
mvn clean package
```
Copy to Clipboard Toggle word wrap
If the build is successful, you should find the jboss-as-helloworld-mdb.war WAR file in the helloworld-mdb/target directory.

If you have not already done so, register the administered objects for the queues and topics used by the example, by editing the JBoss EAP configuration.

In your JBoss EAP installation, open the standalone/configuration/standalone-full.xml configuration file with a text editor, and add the following highlighted administered objects to the activemq-rar.rar resource adapter:

Where the preceding configuration adds the following entries to the JNDI registry:

java:/queue/HELLOWORLDMDBQueue: References a javax.jms.Queue object that connects to the HELLOWORLDMDBQueue ActiveMQ queue (where the queue name on the JBoss A-MQ broker is specified by the PhysicalName config property).
java:/queue/HELLOWORLDMDBTopic: References a javax.jms.Topic object that connects to the HELLOWORLDMDBTopic ActiveMQ topic (where the topic name on the JBoss A-MQ broker is specified by the PhysicalName config property).

In the helloworld-mdb example, these administered objects are accessed by the servlet class, HelloWorldMDBServletClient (but not by the message driven bean classes). For example, the HelloWorldMDBServletClient class injects these JNDI entries, using the @Resource annotation, as follows:

import javax.annotation.Resource;
...
import javax.jms.ConnectionFactory;
...
import javax.jms.Queue;
import javax.jms.Topic;
...
public class HelloWorldMDBServletClient extends HttpServlet {
    ...
	@Resource(mappedName = "java:/ConnectionFactory")
	private ConnectionFactory connectionFactory;

	@Resource(mappedName = "java:/queue/HELLOWORLDMDBQueue")
	private Queue queue;

	@Resource(mappedName = "java:/topic/HELLOWORLDMDBTopic")
	private Topic topic;
    ...

import javax.annotation.Resource;
...
import javax.jms.ConnectionFactory;
...
import javax.jms.Queue;
import javax.jms.Topic;
...
public class HelloWorldMDBServletClient extends HttpServlet {
    ...
	@Resource(mappedName = "java:/ConnectionFactory")
	private ConnectionFactory connectionFactory;

	@Resource(mappedName = "java:/queue/HELLOWORLDMDBQueue")
	private Queue queue;
