JSP pass variable from jsp request form to java back to jsp

How do I pass form info from jsp to java to jsp again.

I have this jsp form that when I submit it, it is passed to another jsp page directly that displays those info. But then I want to process those information first in a java file before passing it again to jsp.

I do something like this in jsp..

  <form method="POST" action="process.java" >
     ....
  </form>

then on process.java I use request.setAttribute("data") to stored the processed data. But how do I redirect it back to an html view file? Sorry new user here.

Sorry this should be really a common question but i just want a simple answer for it.

You can use redirect in HttpServletResponse:

response.sendRedirect("next.jsp"); // next.jsp is your next jsp you want to show

By the way, your Java has to extend Servlet API interface to be invoked.

You need to POST your form data to a servlet which is mapped to particular URL for example /process and container will delegate that request to mapped Servlet
