Hi, I am beginer having a servlet code: RequestDispatcher rd=application.getRequestDispatcher("/RequestDisTwo"); rd.include(request,response); is working fine. but instead of include if i am writing : rd.forward(request,response); getting Exception: exception
javax.servlet.ServletException: Servlet execution threw an exception
I havr the feeling there are two things going on here.
Firstly, 'forward' requires all of the response to come from the forward resource. If anything has already been sent to the client and is buffered, the buffer gets cleared first. If the buffer cannot be cleared, an Exception is thrown. This is the initial problem you should solve: make sure nothing is getting sent.
When clearing the buffer, javax.servlet.ServletResponse.resetBuffer() is called. If you check the API, this method has been in the Servlet spec since version 2.3, and Servlets 2.3 have been supported since Tomcat 4.1.36
This is the second issue, and I have the feeling you have an incorrect jee or Servlet JAR on your file system somewhere...
