Hey thanks, I was wondering what could cause this. I guess the thing
that surprises me is that there wern't errors when the webapp started
up. Sounds like something we should plug. Would be good if you could
document this in a JIRA ticket so that it doesn't get forgotten.

Re: java.lang.NullPointerException: Module 'null' not found.
Posted by bue <bu...@gmail.com>.
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.

Re: java.lang.NullPointerException: Module 'null' not found.
Posted by Niall Pemberton <ni...@gmail.com>.
Can you post more information - the relevant parts of your struts
config. Also are you using modules (if so what) and how are you
navigating to your "submit_jsp" - i.e. via an action or directly?
