5.2. Deploy the Apache Camel Servlet
Overview
This tutorial takes a standard Apache Camel example (the
camel-example-servlet-tomcat example) and shows you how to deploy it into a Web server, by packaging the application as a WAR.
Prerequisites
The following prerequisites are needed to build and run this example:
- Either of the following Web servers are installed:
- JBoss Web Server, or
- JBoss Enterprise Application Platform
- Java version 1.7 or later is installed.
- Apache Maven 3.0.0 or later is installed.
- Maven is configured to access the JBoss Fuse repositories, as described in Section 3.1, “Preparing to use Maven”.
- You have access to the Internet, so that Maven can download dependencies from remote repositories.
Install Apache Camel
To obtain the code for the
camel-example-servlet-tomcat example, you need to install the Apache Camel kit, apache-camel-2.15.1.redhat-621084.zip, provided in the extras/ directory of the JBoss Fuse installation.
Install the Apache Camel kit as follows:
- Find the Apache Camel kit at the following location:
InstallDir/extras/apache-camel-2.15.1.redhat-621084.zip
- Using a suitable archive utility on your platform, unzip the
apache-camel-2.15.1.redhat-621084.zipfile and extract it to a convenient location,CamelInstallDir.
The camel-example-servlet-tomcat example
The
camel-example-servlet-tomcat example is located under the following sub-directory of the Apache Camel installation:
CamelInstallDir/examples/camel-example-servlet-tomcat/
Build and run the example
To build and run the
camel-example-servlet-tomcat example, perform the following steps:
- Build the
camel-example-servlet-tomcatexample using Maven. Change directory to theCamelInstallDir/examples/camel-example-servlet-tomcat/directory, open a command prompt, and enter the following command at the command line:mvn package
If this command executes successfully, you should be able to find the WAR file,camel-example-servlet-tomcat-2.15.1.redhat-621084.war, under thecamel-example-servlet-tomcat/targetsub-directory. - Make sure that the Web server is already running (a simple way to test this is to enter the URL,
http://localhost:8080, into your browser). If you need to start the Web server, you can typically do this from the command line. The command to start the Web server depends on the particular product you are using, as follows:- JBoss Web Server (WS)—open a new command prompt and execute the
startup.shscript from thetomcat8/bin/directory (or thetomcat7/bin/directory, as appropriate). For more details about how to configure and launch the WS, see the Installation Guide from the JBoss Web Server library. - JBoss Enterprise Application Platform (EAP)—for a standalone instance, open a new command prompt and execute the
bin/standalone.shscript. For more details about how to configure and launch the EAP, see the Administration and Configuration Guide from the JBoss Enterprise Application Platform library.
- Deploy the
camel-example-servlet-tomcatexample to the running Web server. Manually copy thecamel-example-servlet-tomcat-2.15.1.redhat-621084.warWAR file from thecamel-example-servlet-tomcat/targetdirectory to the Web server's deployment directory, as follows:- JBoss Web Server (WS)—copy the
camel-example-servlet-tomcat-2.15.1.redhat-621084.warWAR file to thetomcat8/webappsdirectory (ortomcat7/webappsdirectory, as appropriate). - JBoss Enterprise Application Platform (EAP)—copy the
camel-example-servlet-tomcat-2.15.1.redhat-621084.warWAR file to thestandalone/deploymentsdirectory.
- Navigate to the following URL in your browser:
http://localhost:8080/camel-example-servlet-tomcat-2.15.1.redhat-621084/
When the page loads, you should see the following text in your browser window:
- Click the highlighted link in the line
