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!
