How to get jersey logs at server?

I am using jersey for a REST WS. How do I enable jersey logs at server side?

Long story:
I get a clientside exception – but I don’t see anything in tomcat logs [It doesn’t even reach my method]. Since the stack trace is saying “toReturnValue” it did get something from server. But I don’t know what the server said.

Exception in thread "main" java.lang.IllegalArgumentException: source parameter must not be null
