Jetty/Feature/JBoss

Configuring Jetty in JBoss

Support for this feature has been dropped with Jetty 9.
If you feel this should be brought back please file a bug.

To build and run Jetty in JBoss, you need the following:

1. JDK 1.4 (for JBoss 4.0.5) or JDK 1.5 (for JBoss 4.2.x)
2. Maven 2.0.4 or later
3. A JBoss installation
4. Jetty-JBoss module in Jetty (this is in the Jetty-src, under contrib/jboss)

It is not possible to build the Jetty-JBoss module with versions of JBoss prior to 4.0.5. For runtime compability, see the #Compatibility Matrix below. Some JBoss 4.0.x versions require jsp-2.0, as the JBoss web console application appears to be incompatible with jsp-2.1.

Building the Jetty-JBoss Module

After checking out the Jetty-JBoss module, go to the command line and cd to its home directory. Run:

 mvn -P[jdk1.4|jdk1.5] -Djboss.home=path-to-jboss -Djboss.version=jboss-version clean install

where:

• path-to-jboss is the location of your JBoss installation and jboss-version is the version number of your JBoss installation.
• building with profile jdk1.4 includes jsp-2.0 in the SAR, and building with profile jdk1.5 includes jsp-2.1 instead.

Another way to build it is to edit the pom.xml. Edit the <properties> section and fill in the values for the <jboss.home> and <jboss.version> properties. Once you set these in the pom.xml, you can do the build with:

 mvn clean install

Installing the Jetty-JBoss Module

1. Delete the Tomcat files. In JBoss 4.0.x, delete $JBOSS-HOME/server/default/deploy/jbossweb-tomcat55.sar; in JBoss 4.2.x, delete $JBOSS-HOME/server/default/deploy/jboss-web.deployer (or from whichever deployment directory you are using).
2. Ensure you have built the Jetty-JBoss module in $jetty.home/modules/contrib/jetty-jboss.
3. Copy the $jetty.home/modules/contrib/jetty-jboss/target/jetty-JETTY-VERSION-jboss-JBOSS-VERSION.sar to your JBoss deploy directory (where JETTY-VERSION is the version of Jetty you are using and JBOSS-VERSION is the version of JBoss).
4. Notice that the JBoss web-console refers to a Tomcat servlet; you might want to comment that out to make it usable. To do so, edit the $JBOSS-HOME/server/default/deploy/management/console-mgr.sar/web-console.war/WEB-INF/web.xml file and comment out this section:

 
 <servlet>
     <servlet-name>Status Servlet</servlet-name>
     <servlet-class>org.jboss.web.tomcat.tc5.StatusServlet<span class="code-tag"></servlet-class>
 </servlet>
 
 <servlet-mapping>
     <servlet-name>Status Servlet</servlet-name>
     <url-pattern>/status</url-pattern>
 </servlet-mapping>

Configuring the Jetty-JBoss Module

By default, Jetty is configured with the following:

• A thread pool containing a minimum of 10 and a maximum of 250 threads
• A SelectChannelConnector on port 8080

This configuration is contained in the META-INF/jboss-service.xml file inside the SAR.

To change the port, add other types of connectors–(SSL, AJP13–configure a request log, or change the thread pool, you need to un-pack the SAR to a temporary directory, edit the META-INF/jboss-service.xml file, repack it and copy the modified SAR to the JBoss deploy directory.

Enabling Statistics

Edit the META-INF/jboss-service.xml file from the SAR (you need to unpack it first). Uncomment the following lines:

 
    <!-- Uncomment for statistics
       <New id="StatsHandler" class="org.eclipse.jetty.handler.StatisticsHandler">
        <Set name="handlers">
     -->
 
     <!-- Uncomment for statistics
       </Set>
      </New>
     -->

Now re-jar the modified SAR. You can use the StatisticsHandlerMBean to retrieve the statistics using the JMX console.

Jetty 7 has a Statistics Servlet that you can configure in the JBoss management webapps instead of the Tomcat org.jboss.web.tomcat.service.StatusServlet servlet.

Using Jetty-SAR and Struts Tiles

If you are using Struts Tiles for your web-application, you should probably edit webdefault.xml in the SAR and change dirAllowed to false. If you do not, when you try to insert a tile value (or override one) with an empty value, Jetty supplies a directory listing for that tile.
