I had developed a J2EE application(a EJB module, the client module is a stand alone java application, I don't have any Web modules)
using Websphere Studio Application Developer 4.1, created an EAR file with all the deployed code.I Imported this EAR file (developed on WSAD 4.1) onto WSAD 5.1 and when I try to rebuild this project I get this error message
CHKW6000E: J2EE Web Services validation failed for module com/ibm/etools/commonarchive/impl/ApplicationClientFileImpl incompatible with com/ibm/etools/commonarchive/EJBJarFile. ConnSysTest4.0Client

(ConnSysTest4.0Client is my client project which has a stand alone java program , along with some utility classes.)

I have also tried to develop and build the same above mentioned project on WSAD 5.1 from scratch, and I still get the same error message

could someone please help me out (I am in a crunch right now :-( ), I would be eagerly waiting a response

Thanks
