jsp:include not working on iP6

[MSD]

Hi,
I have a JSP page(page1.jsp) that uses the jsp:include tag to include another JSP page(page2.jsp) in its body.
The problem I am facing is that when I access page1.jsp without initializing page2.jsp first, the JSP engine throws an error saying include call failed. Here's the corresponding entry in error log :-

[26/Sep/2002:04:25:16] warning (12699): RequestDispatcher: include call failed
[26/Sep/2002:04:25:16] failure (12699): Internal error: servlet service function had thrown ServletException (uri=/page1.jsp): javax.servlet.ServletException: RequestDispatcher: include call failed, stack: javax.servlet.ServletException: RequestDispatcher: include call failed

        at com.iplanet.server.http.servlet.NSServletRunner.Service(NSServletRunner.java:464)
, root cause: 

However, when I access page2.jsp first and then access page1.jsp (in this case, page2.jsp has been initialized), the include call works fine.
I didn't have the same problem on iP4.1, but am now getting it after upgrading to iP6
Maybe there's some configuration that I need to do?
All help appreciated.
Thanx,
Mohammed.

well,
i don't have a solution to ur question but i have question for u instead...
"were u able to use jsp:include in iP4.1?"
i am not able to use it. it simply doesn't allow jsp:include, jsp:forward etc which is standard JSP...
i also observed we have USEBEAN tag instead of jsp:useBean of JSP ...
i dont know if that has anything to do with Service Pack version...
thanks & sorry for the counter question
