Subject RE: jsp:include semantics?
Date Thu, 06 Feb 2003 14:11:23 GMT
OK, oops, the path should have been relative to the webapp.  But now I'm seeing a different
set of problems.  

My original call is to a servlet /myapp/myservlet/param1/param2.  That servlet forwards to
a jsp /myapp/wrapper.jsp.  The jsp then includes the same servlet that called it, but changes
the path, e.g., 

<jsp:include page="/myapp/myservlet/newparam1/newparam2" flush="true"/>

When I set a breakpoint, in the servlet, it seems as if the request object is the same request
object as the one from the original servlet.  Specifically, the URI doesn't reflect the changes
that were made in the jsp.  It's spooky...

The path you specify as an argument to <jsp:include> has to be context
relative.  If "/mywebapp" is the context path of your webapp, then you
should say:

  <jsp:include path="/myservlet" .../>

instead of:

  <jsp:include path="/mywebapp/myservlet" .../>

In addition, if you're using a web connector (instead of Tomcat
standalone), you'll need to tell it to forward "/myservlet" paths to
Tomcat -- this would also affect a direct requests to your servlet from a
