Subject [jira] [Commented] (FELIX-4589) Problem with forwarding from one servlet to another
Date Wed, 30 Jul 2014 11:59:39 GMT

J.W. Janssen commented on FELIX-4589:
-------------------------------------

Strange, because I tried the same thing with your demo (splitting the caller and forward servlets
in 2 separate bundles) and this works fine when using {{HttpServletRequest#getRequestDispatcher}}.
Would it be possible for you to adapt your demo code to show your failing set up?

> Like in an issue FELIX-2774 (https://issues.apache.org/jira/browse/FELIX-2774) I'd like
to have a several servlet bunles installed with embedded OSGI framework. I'm using servlet
bridge for request's management between sevlets bundles. In order to pass the information
between servlets I want to use request dispatcher to forward (or include) http queries from
one servlet to another. 
> Even when I have two servlets registered in one bundle I cannot make a forwarding from
one servlet to another.
> ServiceTracker
> httpService.registerServlet(TestServlet.SERVLET_ALIAS,	new TestServlet("Test servlet"),
null, null);			httpService.registerServlet(ForwardServlet.SERVLET_ALIAS,	new ForwardServlet("Forward
servlet"), null, null);
> Trying to do the following in a TestServlet doGet method will cause error:
> RequestDispatcher rd = getServletContext().getRequestDispatcher(ForwardServlet.SERVLET_ALIAS);
> rd.forward(req, res);
> For org.apache.felix.http.bridge-2.0.2.jar error will be NullPointerException on 'rd'
variable, for version 2.2.0 the same, but for version 2.3.0 it's going to be endless loop
and stackoverflow error.

project)
