1.Calling JSP in servlet, I tried several ways:
private performTask(HttpServletRequest req,HttpServletResponse res) throws ...
{
.....
// EmpPay is a instance of JavaBean
// way1
((com.sun.server.http.HttpServiceRequest)req).setAttribute("EmpPay",EmpPay);
((com.sun.server.http.HttpServiceRequest)req).callpage("/EmpPay.jsp");
// alternative way2
req.setAttributs("EmpPay",EmpPay);
res.sendRedirect("/EmpPay.jsp");
// alternative way3
req.setAttributs("EmpPay",EmpPay);
getServletContext().getRequestDispatcher("/EmpPay.jsp").forward(req,res);

 I was coding and testing in VAJava,both way1 and way3 were succesfully in VAJava and got correct output from JSP.
 my first question is : which one is Java Standard(pure Java) way as aboved to call JSP in servlet ? Somebody told me the way1 will not be supported in Standard Java.

2. Our deploy environment is WebLogic,I got error information in WebLogic as following:
 Compilation of 'c:\weblogic\...\EmpPay.java failed :
 c:\weblogic\..\_EmpPay.java:110:'try' ????????? 'catch' ?? 'finally' ...

 What I should add to my JSP ? who can provide me a example ?

thanks a lot
