The code that you have found comes from the LayoutDefinitionTag.
This tag should only ever occur on the page that defines the common
layout (not on pages using that layout). Because of this, certain
assumptions are made:
1) Layout JSPs (those using s:layout-definition) are only ever
executed by Stripes, and in fact by the layout-render tag. You
should not be forwarding to those yourself
2) The only way the s:layout-render tag ever executes the layout is
via an INCLUDE
3) Therefore, when used properly, the call to find the include_path
should work just fine
I'm not sure exactly what you're doing differently that is causing
this problem. Can you perhaps show us the JSP that is invoking the
layout?

My reading of the servlet spec shows that, using getAttribute
('javax.servlet.include.servlet_path')-which is the only method
used by
net.sourceforge.stripes.tag.layout.LayoutDefinitionTag.doStart() -
will work only if the include was used. since you should be
able to forward to the jsp page before that page invokes the layout-
definition using include, the above method will have a wrong value
since the parameter will not be there. at this point, it will be
under getAttribute("javax.servlet.forward.servlet_path"); I
therefore think stripes should consider this as well since the
relegation of the control to the jsp can come from anywhere.
I dont know how to fix this though

a short section of my web.xml. the urlRewriter creates the name of
the jsp file requested and forwards to it. Stripes intercepts the
forward to do instantiation before jsp is written

Do you have the URLRewrite filter mapped only to the REQUEST
dispatcher, or does it also kick in on INCLUDEs? It sounds to me
like the Stripes code is expected to only ever be called through an
include, and in this case is not because something is intercepting
in the middle and doing something else. Is that the case? And if
so, is there any need to have the URLRewrite work on anything
except requests coming in from outside the container?

Subject: [Stripes-users] Forwarding to a jsp that uses stripes
taglib from a filter
I have an intercepting filter that rewrites a url and forwards to
the url (URLrewriter http://tuckey.org/urlrewrite/ )
wrk lik
/contact will be retwritten as /contacts.jsp and forwarded to the
jsp. However the jsp throws a very nice NPE. dont know. a little
dig into the stripes
code reveals the execption on this line
// Assuming that the layout definition page is always
included, the following line gets
// the name of the page the tag is sitting on, as per
Servlet 2.4 spec, page 65.
String name = (String) getPageContext().getRequest()
.getAttribute('javax.servlet.include.servlet_path');
what can i do, to get round it. I have attached the stack trace
