[seam-issues] [JBoss JIRA] (JBSEAM-4146) "no file extension in servlet path" exception whenever a servlet throws an exception

"no file extension in servlet path" exception whenever a servlet throws an exception ------------------------------------------------------------------------------------ Key: JBSEAM-4146 URL: https://issues.jboss.org/browse/JBSEAM-4146 Project: Seam 2 Issue Type: Bug Components: Core Affects Versions: 2.1.1.GA Environment: Java 6, Tomcat 6 Reporter: Matthew Lieder Assignee: Marek Novotny Labels: testcase Fix For: 2.3.0.BETA1 Attachments: SeamTestcase1.zip 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.
