I am trying to send redirect to a JSP file after processing my form.

I see execptions in my console -> Cannot forward. Response already committed.Why do I get this error and what should I do to solve this?

    Don't abuse a JSP as controller. That logic belongs in a servlet. – BalusC Oct 01 '12 at 21:50
  • Don't try to forward after sending a response? – user207421 Oct 01 '12 at 22:00
  • I am trying to convert the servlet code to JSP scriptlet. What can I do instead? When I submit it should redirect me to success page. – smiley Oct 01 '12 at 22:37

    Why are you converting a servlet to a JSP? That's a step backwards and falls under "using the wrong tool for the job". – BalusC Oct 01 '12 at 23:09
  • We have a code freeze where we can't deploy class files. While JSP can be easily deployed without getting approvals. I am actually coding a similar page like the existing one.To ensure my code is working, I am rewriting the servelet to a jsp. – smiley Oct 01 '12 at 23:18
  • I am writing a JSP (form) which calls another jsp to process on form submit. It has to redirect to success jsp after the submission is successful. – smiley Oct 01 '12 at 23:22
  • Well, This was a management decision anyways. I would prefer to get some suggestions/answers from you :) – smiley Oct 03 '12 at 06:37
