Hi
   Can somebody lemme know how can i track the userId and password in related java servlets...or how should I pass the same to further servlets after I login. I am new to servlets so don't have much hold over it..I have been adviced to use beans for the same...but I am again new to the concept of java Beans..can someone guide through..as to how to accomplish the task..?
Thanks in advance for that!!

A simple way is to use session attributes. For example, in one servlet you can set a session attribute like this:

request.getSession().setAttribute("user", "simplyAns");

Then in another servlet, you can retrieve the value like this:

String user = (String)request.getSession().getAttribute("simplyA ns");

If you want to get a bit more complicated, you can look into defining security roles in your web.xml and having the container (e.g. Tomcat) enforce authentication automatically. But I personally find this approach cumbersome and I use something similar to what I laid out above.

    It is very easy to track variables using session option.


          once a session object is set,it is available to all servlets/jsp running in the same context.


    The code for creating session is as foolws:

   HttpSession session = request.getSession(true);

        To create a session object:

      session.setAttribute("obj","wrox");

     Here "obj" is the session object and "wrox" is the value for the session object "obj".

    u can get the session attribute value using in other jsp or servlets:

   session.getAttribute("obj");

    This returns the value for the session object "obj" i.e, "worx".


   Note in JSP session is an implicit object,so by enabling session="true" in the page directive session object is available.

     Try this!
