Exceptions thrown after a jsp:include

Question

Hi all,
          At the beginning of my JSP, I can't use the JSP include directive because I
          need to do a specific include from another webapp servlet context. Thus I
          wrote my own include tag <mytag:include page="" context=""/> where I use
          RequestDispatcher.include().
          But then I am facing the following problem with this JSP :
          [myjsp.jsp]
          <mytaglib:include page="" context=""/>
          <mytaglib:stgElse/>
          if the second tag <mytaglib:stgElse> is throwing a JspException, and if I
          use the error handling system of the webapp :
          [web.xml]
          <error-page>
          <exception-type>javax.servlet.jsp.JspException</exception-type>
          <location>/web/en/pf/error.jsp</location>
          </error-page>
          I get : "java.lang.IllegalStateException: Cannot forward a response that is
          already committed"
          because it tries to do a forward after an include which needed a flush of
          the buffer previously, what means the response was already comitted.
          Thus the question is : how to handle exceptions coming after an include was
          done, that is to say after a flush of the buffer has already been committed
          Thanks for any help.

Answer 1

In the doc, it states:
sendRedirect
If the response has already been committed, this method throws an
IllegalStateException. After using this method, the response should be
considered to be committed and should not be written to.
In other words, you must not do anything before or after with the response.

Friends,
How do I do a redirect either through HttpServletResponse.sendRedirect ()or
<jsp:forward /> in a JSP that does a <jsp:include /> at the top.
I am getting a IllegalState exception.
Thanks
