i am using Struts 1.2.8 + JBoss Portal 2.2.1 SP2. I managed to compiled all source with no error. This error, "No bridge set", appear during accessing the portlet page.

With above my portlet.xml, am i miss out anything important that cause this error?

I'm having the very same problem here.

trying to get the servletcontext within my portlet.

protected void doView(RenderRequest rRequest, RenderResponse rResponse) throws PortletException, IOException, UnavailableException
 {

 ServletContextProvider prov = new JBossServletContextProvider();
 HttpServletRequest hreq = prov.getHttpServletRequest(this, rRequest);
...
}

im getting this error:

oops, wrong stacktrace, the one above was for prov.getServletContext(portlet), basically it should make no difference, any call to the JBossServletContextProvider ends up in the "no bridge set" exception.

ok, this is the right stacktrace:

09:19:13,817 ERROR [ContentPortlet] The portlet threw an exception

hi,
i found a solution for this problem:

as of cvs version 1.89 of /portal-core-sar/META-INF/jboss-service.xml the bridge interceptor has been switched off temporarily.

my solution:
i added the following in line 281 (after SessionPostDispatch) to the file jboss-service.xml

<depends-list-element>portal:service=Interceptor,type=Portlet,name=Bridge</depends-list-element>

restart jboss, then it works. of course I do not know why the Bridge interceptor has been deactivaed, maybe there exist good reasons for doing this?

now i have additional questions:

as said, I use the following code to get the servletRequest

JBossServletContextProvider prov = new JBossServletContextProvider();
HttpServletRequest hreq = prov.getHttpServletRequest(this, rRequest);

imho the returned HttpServletRequest should behave like a standard servlet's HttpServletRequest, but it doesn't! eg: getParameter never returns any parameter values, there are simply no parameters at all; also hreq.getServletPath() returns null.

is this normal behaviour? is there a documentation about what to except when using the JBossServletContextProvider's HttpServletRequest?

thank you very much for any answers!
