I am using IBM's Rational Application Developer. I have an ant script that contains the Java2WSDL task. When I run it via IBM, it gives compiler errors unless I include the j2ee.jar file in the classpath via the run tool (it does not pick up the jar files in the classpath in the script). However, I need to be able to call this script programmatically, and it is giving me this error: "java.lang.NoClassDefFoundError: org.eclipse.core.runtime.CoreException" I'm not sure which jars need to be added or where? Since a simple echo script runs, I assume that it is the j2ee.jar or another ant jar that needs to be added. I've added it to the project's buildpath, but that doesn't help. (I also have ant.jar, wsanttasks.jar, all the ant jars from the plugin, tools.jar, remoteAnt.jar, and the swt - all which are included in the buildpath when you run the script by itself.)

Script:

<project default="build" basedir=".">
