Hello,

I am using Hibernate version 2-1 and trying out with jBPM on JBoss 3.2.5 and 3.2.6. I am facing a problem looking up the datasource in JBoss ..
Ant Version 1.6.2

After struggling a lot, I have narrowed down the issue to a "ClassNotFoundException" in NamingHelper class. I believe that this could be due to some version mismatch... but was wondering if anybody has run into this issue...

I have tried providing jnpserver and jnp-client jars, but does not seem to resolve the issue...
