Glassfish Error when deploying working GF 2.1 to Glassfish 3 and switching to maven at the same time - Killing me!

Everything builds just fine in Maven and Ant, but will only deploy when building with Ant. It is an EJB jar I am deploying that is @Stateless and has @WebService tags as well

Everything builds just fine in Maven and Ant, but will only deploy when building with Ant.

Then there is a difference somewhere between the EJB-JAR built by Ant and the one built by Maven. But I don't think the stacktrace will help here.

Could you tell us more about the structure of your app? Can you run jar xvf myejb.jar on both of your EJB-JARs and post the output? Can you show the structure of your maven project (e.g with tree myproject)? Can you show the pom.xml?

Also, why did you mention GF 2.1 in the title of the question? Does this have anything to do with the problem? Does the EJB-JAR built by Maven deploy on GF 2.1?
