Question

I am trying to use Jetty with ant and for the most part I’ve followed the instructions outlined here. The webapp starts up ok but I still to make a few more adjustments:

• Increase JVM memory (set the -Xms, -Xmx, and -XX:MaxPermSize)
• Enable remote debugging

My ant task is defined as such:

  <target name="jetty" depends="make-webapp">
    <taskdef resource="tasks.properties" loaderref="jetty.loader">
      <classpath>
        <fileset dir="jetty-lib/">
          <include name="eclipse-jdt-core-3.1.1.jar" />
          <include name="jetty-6.1.26.jar" />
          <include name="jetty-ant-6.1.26.jar" />
          <include name="jetty-naming-6.1.26.jar" />
          <include name="jetty-plus-6.1.26.jar" />
          <include name="jetty-util-6.1.26.jar" />
          <include name="jsp-2.1-jetty-6.1.16.jar" />
          <include name="jsp-api-2.1-glassfish-9.1.1.B51.25.p1.jar" />
          <include name="jsp-2.1-glassfish-9.1.1.B51.25.p1.jar" />
          <include name="servlet-api-2.5-6.1.5.jar" />
        </fileset>
      </classpath>
    </taskdef>

    <mkdir dir="target/work" />
    <jetty tempDirectory="target/work">
      <webApp
        name="myapp"
        warfile="target/myapp"
        contextpath="/myapp" />
    </jetty>
  </target>

target/myapp has everything it needs including the WEB-INF/lib and WEB-INF/classes folders.

So how can I increase memory and enable remote debugging with this set up?

This might answer your question: http://ptrthomas.wordpress.com/2006/10/10/how-to-start-and-stop-jetty-from-ant/

Use jvmarg to put the required memory and remote debugging settings.
