Java EE (Java Enterprise Edition) General Discussion

I have a jsp to log in new users. Once a user logs in, I set a userId session attribute in my login servlet.

session.setAttribute("userId", userId);

If the login is valid, I flow to a second servlet to retrieve information based on that user. However, when I try and access the session userId, I get a null value.

userId = (String) session.getAttribute("userId");

Any ideas why I might be losing session information in my second servlet?

Thanks!
