Summary: Dispatcher.forward and getPathInfo() != null causes
stack overflow
Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: major
Priority: P2
Component: Servlet & JSP API
AssignedTo: dev@tomcat.apache.org
ReportedBy: em...@cs-ware.de
web.xml:
----
<servlet>
<servlet-name>ShowFile</servlet-name>
<servlet-class>submissioninterface.servlets.controller.ShowFile</servlet-class>
</servlet>
<servlet>
<servlet-name>ShowFileView</servlet-name>

<url-pattern>/servlets/ShowFileView</url-pattern>
</servlet-mapping>
----
ShowFile.java contains:
request.getRequestDispatcher("ShowFileView").forward(request, response);
ShowFileView.java:
contains just a hellow-world-output.
Open /servlets/ShowFile/sth in browser and get the stack overflow. Changing
"/servlets/ShowFileView" to "/servlets/ShowFileView/*" didn't help.
