JSP forward not working OK from JSP include

           Summary: JSP forward not working OK from JSP include
           Product: Tomcat 4
           Version: 4.0.4 Final
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Jasper
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: yair.lenga@ssmb.com


My main JSP file include other JSP files, some of them are simply "forward" to
the real context page (also a JSP file). It looks that if page "a" does
"jsp:include" to page "b", which will use "jsp:forward" to different page "c",
then the output of "c" will replace the output of "a".

It looks as if a "forwarded" in an included page will cause the "main" page to
be replaced by the "forMy structure looks like:

Main file "a.jsp"

<h1> BEGIN </h1>
<jsp:include page="a1.jsp" />
<jsp:include page="a2.jsp" />
<jsp:include page="a3.jsp" />
</h1> END </h1>

The small files a1.jsp, a2.jsp, a3.jsp contain:
a1.jsp: <jsp:forward page="a1x.jsp" />
a2.jsp: <jsp:forward page="a2x.jsp" />
a3.jsp: <jsp:forward page="a3x.jsp" />

The files a1x.jsp, a2x.jsp, a3x.jsp contain:
a1x.jsp: <h1> a1x </h1>
a2x.jsp: <h1> a2x </h1>
a3x.jsp: <h1> a3x </h1>

The pages are placed into the ROOT context of a default TOMCAT install. When the
page is fetched I was expecting:
BEGIN
a1x
a2x
a3x
END

Instead, I'm only seeing:
a1x


It looks as if the <page:forward> in "a1.jsp", cause the whole request to be
forwarded to "a1x.jsp". Instead of just forwarding the "a1.jsp" request to
"a1x.jsp", it behave as if the forward request was issues from "a.jsp".

I checked the code with Jrun - and it behaves the way I expect it to be. I'm not
if the specification are clean about this behavior, but this behavior is wrong.
It will cause a JSP page to behave differently if any included page is using the
"jsp:forward" directive.
