I have this code which needs to be migrated from a different Webservice codebase to mine. I did it and when i hit my webservice now, I have a callbackhandler (which i migrated from the other WS) which has the following code, which always returns WSSubject.getCallerSubject() as null. I am totally new to the callbackhandler concept.
The second line in the try block is the culprit. It throws nullpointerexception since Subject is null. Please help me out.
