I had exactly the same error message (with struts distribution 1.3.5 and
Weblogic 8.1sp5).
It turned out that the struts-config.xml file was missing (or at a wrong
place).
After supplying a proper struts-config.xml file in the proper place
(WEB-INF/struts-config.xml)
the error disappeared.
This is the stacktrace as it appeared on the log at the time of the error:
java.lang.NullPointerException: Module 'null' not found.

Hope this helps.
