Design problem

Hi ,

I want to develop a code which can take care of following senario

We want to develop a form which accepts and processes user request in background

Here is the use case

1)User fills the form information (JSP )
2)Hits on a submit on the form
3)On submition , we will call a servlet which will do validation of the form data and then the servlet will call a status jsp
4)The status jsp will show message , that request is submitted and then will make a call for processing. ( Processing takes about 2 mins)

The problem that I am facing is

Even if I include the process call at the very end of status jsp , still the status jsp appears after the process call is complete.

Basically what should be done so that method calls happens after the jsp is displayed?

You need to do the long-running processing in a separate thread dedicated to that purpose.

It is sorta covered in the JavaRanch Style Guide.
