NPE in StandardHostValve.invoke

[Peter Nabbefeld <Pe...@gmx.de>]

Hello,

I've Tomcat and Apache httpd using mod_jk2. The catalina log file contains
the following error message:

2003-10-04 16:09:03 CoyoteAdapter An exception or error occurred in the
container during the request processing
java.lang.NullPointerException

BTW: Tomcat is running from the JOnAS-3-3-Tomcat bundle (including Tomcat
4.1.27).

I would think, that there is some wrong configuration in server.xml. After
checking the source code, I think that 'context.getLoader()' is null (the
context is checked right before, and 'Thread.currentThread()' should never be
zero). Perhaps I've not the appropriate rights for anonymous access? Any idea?

Kind regards

Peter Nabbefeld
