Exported ant script -- NoClassDefFound?

Question

I've exported ant script from workshop (wls9.2 eclipse) and I was able to build the app.war (web services) ok.
However I saw message like this:
"assembly: Imput fileset contained no files, nothing to do."
And when I deployed the war to server and tried to access the webservices, it gave me NoClassDefFound error.
Also I noticed that the ".staging" directory has empty "lib" dir under it.
Does anyone know how to fix it?
Here is the generated build.xml and workspace.xml.

Answer 1

It looks a bug to me. The exported ant script does not take care the jar files setup in the classpath in workshop/eclipes and copy them to the WEB-INFO/lib directory.
