Request Dispatcher question

Question

Hi all,
I have a simple question based on RequestDispatcher.
When we dispatch a file in our servlet, where should we place RequestDispatcher --- Within try block or after try, catch block as defined in this program
Please see the coding/program---------------
// import all necessary packages
public class SimpleServlet extends HttpServlet
public void doGet()throws ServletException,IOException
try
Here I am retrieving data from database and then store them into bean,and doing some coding.
This Servlet will call MyJsp.jsp file.
dispatch="/jsp/MyJsp.jsp";
Should we define RequestDispatcher here ?
catch
// OR here---------
RequestDispatcher dispatcher=request.getRequestDispatcher(dispatch)
dispatcher.forward(request,response);
} // end doGet() method
} // end class
Thanks

Hi,
It`s better to use outside try{}catch{} block if you forward to a page based on some condition like..
try{
if(i.equals("soemthing")){
dispatch="/jsp/MyJsp.jsp";
else{
dispatch="/jsp/Error.jsp";
catch{}
RequestDispatcher dispatcher=request.getRequestDispatcher(dispatch)
dispatcher.forward(request,response);
OR if u`r going to forward to a single page whatever be the condition then you can use Dipatch inside the try{} block itself.
