ear deployment from 4.0.3SP1 doesn't work on 4.2.2.GA

[jamicide]

I have an ear working on v4.0.3SP1 (linux) which I am migrating to v4.2.2.GA (linux).

When I deploy the .ear file to v4.2.2.GA, while trying to deploy a .war contained within the .ear the deployer will throw a ClassDefNotFoundError exception. In an attempt to get this ear working I got around several ClassDefNotFoundErrors by copying some .class files from the .war into a .jar file which is also contained in the .ear.

Following this, I now I get

org.jboss.ws.WSException: Cannot obtain method parameter mapping for message part 'licenseKey' in wsdl operation

as jboss is trying to deploy the .war of the package. At this point I am unsure how to overcome this problem.

Any suggestions on what might be going wrong (with either problem)? Thanks in advance!

Update:

the WSDL error had to do with some incorrect config in my WS .mapping.xml files that version 4.0.3SP1 must not pick up on.

Any thoughts as to the ClassDefNotFoundErrors is still appreciated.
