I am working in a project where for an EJB environment for logging the messages we are using Log4j. Here we are using nested diagnostics contexts (NDC)/MDC to differentiate logging requests from different clients. The control flow in my application is as follows :-
Servlet1 --> Servlet2 --> EJB [ 1... n]
Also as usual there are bean to bean calls.
The NDC.push(hostname) is being done in the "doPost(HttpServletRequest req, HttpServletResponse res)" of Servlet 1.
Currently what is happening is, on using NDC/MDC, all the logger stmts in Servlet1 are getting printed properly with correct user name. But the moment control comes in Servelt2 onwards, the user info is getting missed out.Is there someting in particular which needs to be taken care of ??? Or How do we achieve this?
log messages are like this
INFO - [NITIN.pune.tcs.co.in] [ExecuteThread: '11' for queue: 'default'] - Calling CreateRequest ("ServiceCall" , svcName) on the class RequestFactory
INFO - [NITIN.pune.tcs.co.in] [ExecuteThread: '11' for queue: 'default'] - Making a ervice call request inside CreateRequest(String request , String subject) of class RequestFactory
