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

RE: NullPointerException at ActionServlet.java:1003 using JRun4; work OK under Tomcat/JWSDP1.2
Posted by Tim Lucia <ti...@yahoo.com>.
I have solved this myself. It appears that JRun4 considers
"tim.web.xml" as part of "web.xml", and so it tried to load a config
file that did not exist.
(Any Struts developers reading?? -- Would it be possible in a future
release of Struts to actually say "resource not found:
/WEB-INF/module/struts-config-module.xml" rather then
NullPointerException?)
