NullPointerException at ActionServlet.java:1003 using JRun4; work OK under Tomcat/JWSDP1.2

[Tim Lucia]

All,

I have a struts application using modules which deploys fine under
JWSDP1.2/Tomcat (5, I think), but when I deploy it under (trial edition
of) JRun4, I get 

java.lang.NullPointerException
        at
org.apache.struts.action.ACtionServlet.parseModuleConfigFile(ActionServl
et.java:1003)
.
.
.

Peeking at the source, it looks like it's trying to read a config file,
presumably for my module.

Anyone seen this before?  How did you overcome this problem?

Thanks,
Tim
