hi friends, I'm getting following exception on WebSphere 3.5.2 WebAppInvoker X Unexpected internal engine error while processing request java.lang.IllegalStateException: ERROR: Cannot set header. Response already committed. This particlar exception is coming randomly. I'm sure that I'm not updating PrintWriter object after closing. According to Servlet APIs, this exception comes if you use Servlet Redirection. And I'm not using servlet redirection also. Can u please help me out in this matter? What could be the reason behind this problem? I have some code related to HttpSession in my servlet? Is there any specific care that I have to take while using HttpSession? Waiting for ur replies. Thanks and regards Nilesh
either response.sendRedirect or a RequestDispatcher forward command will give this illegal state exception if you've written anything (this includes 'blank' hard returns in JSP's) to the output stream.
you say you haven't redirected, but what about forwarding?
