Matthew Lieder commented on JBSEAM-4146:
----------------------------------------

Thanks Marek. I played around with using rewrite-filter a bit but still couldn't get it working -- the code in getActionURL(...) is looking at getRequestServletPath() which isn't affected by the rewrite so it's still /servlet/exception since that's what the user's browser is pointed that.

Basically anything that makes the test case work while still keeping the seam filter enabled over the entire app (the servlets I have make use of Seam) is acceptable to me. I'll try out the latest snapshot build with your fix on this test case as soon as I can and get back to you with my results.

> Pretty easy to reproduce: call a servlet from a Seam webapp that throws an exception, which will result in a Tomcat HTTP 500 error page that ,instead of displaying the servlet's exception, displays a "no file extension in servlet path" exception.
> See the attached testcase.
> I have yet to find a good workaround; only way seems to be to hack Seam's codebase myself. The problem definitely seems to be in org.jboss.seam.mock.MockViewHandler.getActionURL(...), as indicated by JBSEAM-2921.
