title: How to get jersey logs at server?
body: <p>I am using jersey for a REST WS. How do I enable jersey logs at server side?</p>
  
  <p>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.</p>
