Question

I have a main JSP and process JSP. In process jsp I am committing the response and forward the response to a success page.

 request.getRequestDispatcher("success.jsp").forward(request, response);

I am able to commit the response at the server side. Process jsp is also able to forward the response to success JSP.
But the url shows for example: http://process.jsp?param1=value1&parm2=value2

I want my output to display a clean as in url http://success.jsp

Please Note: This works perfectly fine for Java Servlet, i just tried it.
I am using only JSP instead of Java servelet, since this is our project requirement.

Can anyone suggest me a solution for this?

Answer 1

RequestDispatcher#forward() Is supposed to forward both the request and the response objects to another resource within the server. No response goes back to the client when you do a forward() and this is why the client shows the same initial URL.

For the client to show another URL you could use HttpServletResponse#sendRedirect(). This does go back to the client making it do a new request to the URL you want. So change it to:

response.sendRedirect("success.jsp").

Remember not to commit the response before doing this or you’ll get an IllegalStateException

As to why you say that on a Servlet works, I’m not sure why, but is not how forward() is supposed to work, and JSP are compiled to Servlets so in the end they should behave the same.
