Response Already Committed

Question

          I frequently get errors in the Weblogic log file (actually a nohup.out file) with
          the following error:
          <Sep 16, 2002 4:39:25 PM CDT> <Error> <HTTP> <[WebAppServletContext(5997858,esn,/esn)]
          Servlet failed with Exception
          java.lang.IllegalStateException: response already committed
          What does the mean?
          thanks
          Ryan
          

Answer 1

jsp:include does an implicit flush. If your JSP does an jsp:include and the
          included JSP attempts the redirect then you should see the exception (per
          JSP 1.1 spec).
