The char '0x0' in 'return code: 500

[Rr Kumaran]

Hi All,

I am trying to expose a EJB as webservice using AXIS 1.2 Final. When deployed my ear/ejb on WSAD - WAS 5.0 and trying to consume the web service using AXIS 1.2 generated stubs I am getting below error on the server side.

Exception in thread "main" java.lang.IllegalArgumentException: The char '0x0' in 'return code:  500
Error 500: The char '0x0' in 'java.rmi.RemoteException: CORBA BAD_OPERATION 0 No; nested exception is:
