Can I call getRequestDispatcher more than once?

Question

All,
Does a servlet allows getRequestDispatcher to be called than once?
This is what I'm trying to do. While the server is processing data, I want to forward the user to a temporary page to display "Processing Data". Once
the server got the result, then I want to forward the user to the separate page to display the data. But before forwarding to the second page, I flushBuffer() and reset() the response object. WHen reset(), I got IllegalStateException. How can I fix this? Here is my code snippet:
1. Forward to first page:
getServletContext().getRequestDispatcher(
"/ProcessingNoticePage.jsp").forward(request, response);
2. Flush out and reset:
if(response.isCommitted())
System.out.print("\nresponse is committed");
response.flushBuffer();
System.out.print("\nResetting response");
response.reset();
System.out.print("\nComplete reset");
3. Forward to second page:
getServletContext().getRequestDispatcher(
pageName).forward(request, response);
I got the IllegalStateException on the reset() in step #2. Thanks.

Answer 1

What do you mean by refresh?
The servlet is actually calling another object. THat objects call other objects to perform server side processing that talks over RMI/IIOP. This process might take more than 30 seconds. So in the mean time, I made the servlet forwarding to a temp page to let the user know that data is being processed. Once all the results are back, I set the result to the request obj. and then forward to another JSP page. This (second) JSP page will display the data.
