Get "java.lang.ClassNotFoundException: com.trg.dao.hibernate.GenericDAO" #83

What steps will reproduce the problem?
1. Import generic-dao jars into existing Eclipse Project, configure build-path 
and create necessary classes and interfaces following examples given
2. Try to test created classes deploying de Eclipse Project into Glassfish
3. Get error "java.lang.ClassNotFoundException: 
com.trg.dao.hibernate.GenericDAO" (I made sure the jar containing that class is 
there)

I can't get the jars to work, the project compiles fine all classes and 
interfaces compile just fine. The problem is at runtime when the project gets 
deployed I get the mentioned error (The Project is a Spring based application 
with Hibernate that is currently working fine with my own classes, just wanted 
to test your generic dao library and see if I could replace my persistence 
layer implementation with one based on the generic dao)

The full stacktrace is below:

I'm pretty sure something just went wrong with the Eclipse/Glassfish/project 
configuration somewhere. I would be surprised if this turns out to be a problem 
with the framework itself.
