           Summary: FacesServlet,init() method throws an exception:
                    NullPointerException
           Product: Tomcat 5
           Version: 5.5.20
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: Servlet & JSP API
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: szczyp@o2.pl


I deploy a simple JSF app in Eclipse + WTP (newest version). JSF is the Sun RI
1.1_01, and I do everything as in the tutorial here:
http://www.eclipse.org/webtools/jsf/dev_resource/JSFTutorial-RC3/JSFTools_tutorial.html
FacesServlet has a property <load-at-startup> set to 1, and when I start the
Tomcat server, I get the exception:

After that I, of course, can't start the application.

After many many downloads of JSF, I tried a different version of Tomcat and the
results are (using the same version of Commonsh (4 jars shipped with JSF, JSF
1.1_01 and JSTL 1.1 latest nightly-build):
- works for 5.5.16
- works for 5.5.17
- crashes for 5.5.20

Works means that the server starts without any errors, and the application
starts and works.
There must be some issue with Tomcat 5.5.20 distribution, haven't tested with
6.x yet.
Thanks.
