java.lang.IllegalStateException: Response already committed

[Rajul Konkar]

Hi All,

I am getting following error while accessing my web application deployed in IBM Websphere,
can anybody tell me whats the problem, thanks in advance.

java.lang.IllegalStateException: Cannot forward. Response already committed.
at com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.forward(WebAppRequestDispatcher.java:161)java.lang.IllegalStateException: Cannot forward. Response already committed.

What i found is :

The java.lang.IllegalStateException: Response already committed
exception is thrown by the HttpServletResponse interface during the response
generation process . If the response has been
committed, you cannot execute any method that is related to
HttpServletResponse object modification. For example, if you have written
something in the response buffer, you cannot forward a page using the
RequestDispacher interface methods.

Thanks
Rajul

That can happen in a few different ways, but often means the app tried to redirect after the response has been written.

Without any real information it'll be impossible to know why that's happening.
