urgent - session null

In a application; i have a JSP page which contains a link which points to servlet which serves the image.
Now the problem is when a servlet is called session is null. I am not able to figure out why i am getting the session as null. I am using encodeURL to encode the link (in order to append session id). Also this problem is not consistent. Sometimes it works and other times i get session as null.
Please help.

It sounds like your JSP and the servlet that serves the image are not in the same web application so the session is not shared.

They are a part of same web application. Also i mentioned that it works sometimes but most of the times it gives session is null. Therefore difficult to trace.

There is chance that session is expiring by time
you get to image servlet....
