Well, I think this is all IBM's fault. If I remember correctly, IBM
implemented support for version 0.91 of Java Server Pages in WebSphere AS.
The thing is that the servlet API didn't provide support for some methods
which that version of the specification requires, such as the callPage()
method. So IBM used Sun's internal classes (which you are not supposed to
use, but everyone does that). I recommend you switch to a product which
supports standard Servlet API 2.1 and JSP 1.0, such as JRun or JavaServer
Web Development Kit, or wait until WebSphere supports it. For now I think
you might be able to find it in JSDK 2.0, but I'm not sure. I recommend you
switch to a product based on the final version of the specification.

Hi Petr,
This is the piece of code that I am trying out.It is given in
Websphere 2.0 Documentation.
It uses this class com.sun.server.HttpServiceRequest/Response.
Can you please tell me how do I go about executing this.
Thanks in advance,
