Sorry, it still does not work.

I have a fully functional, non-precompiled web application in dist/war.

I am trying to transform it into a precompiled web app in place, using 
the following Ant tasks:

<taskdef classname="org.apache.jasper.JspC" name="jasper2">
	<classpath id="jspc.classpath">
		<fileset dir="${env.CATALINA_HOME}/common/lib"><include 
name="*.jar"/></fileset>
		<fileset dir="dist/war/WEB-INF/lib"><include name="**/*.jar"/></fileset>
	</classpath>
</taskdef>

<jasper2
	validateXml="false"
	uriroot="dist/war"
	addWebXmlMappings="true"
	compile="false"
	poolingEnabled="false"
/>

When executing the target that contains the tasks with Eclipse 3.1M4 
(which contains Ant 1.6.2), I just get

BUILD FAILED: C:\eclipse-3.1M4\workspace\myapp\build.xml:86: 
java.lang.NullPointerException

My CATALINA_HOME environment variable points to an installation of 
Tomcat 5.0.28. I am using Windows XP SP2.

Is there anything I can do to debug this problem? Where can I read the 
stack trace of the exception?

Regards,

Andreas
