[jira] [Commented] (FELIX-4589) Problem with forwarding from one
servlet to another
[ https://issues.apache.org/jira/browse/FELIX-4589?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14079005#comment-14079005 ]
J.W. Janssen commented on FELIX-4589:
-------------------------------------
Hmm, not sure what might cause this, given that [1] does several tests wrt request dispatching. Perhaps the issue is in the Http Bridge...?

> Affects Versions: http-2.3.0

> 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.
