"Issue with reflections"

Hello,
I have a JBoss server running with a certain JAVA_HOME. I have a pub sub JMS application
running in eclipse. I do some looks using reflections in the JMS application. The JMS
application doesnt throw any error while looking up with reflections but when the server
is running it fails to retrieve the class name. The following is the reflection error.
java.lang.reflect.InvocationTargetException
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source)
at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source)
at java.lang.reflect.Constructor.newInstance(Unknown Source)
Is this an issue with the JVM? I`m assuming tht whenever I run an application from eclipse
its using a different JVM. Also if not is it tht JBoss and the application from ecipse are
referring to the same jdk which is causing the problem? Thanks for reading this post. Any
help is appreciated.

Hi,
what is the exact jdk your are using?
what is the full stacktrace you get? i.e.
how does your code that "dies" look like?

Hi,
you problem is right there :) there is antlr missing from your classpath :)
you can add it by adding dependancy to module org.antrl via manifest.mf or
jboss-deployment-structure.xml
