I have followed the person tutorial for struts basic type and
experienced a problem right at the end. Everything works fine on jetty
(mvn jetty:run-war), but with tomcat (mvn cargo:start
-Dcargo.wait=true), I get a null pointer exception when trying to access
editPerson. The list person is fine. It looks like a problem in the view
layer, but I am not even sure the action is accessed as I can see no
debug info when running tomcat from cargo. Naturally this also causes
the canoo web test to fail with a 404 error for the edit person test. My
struts.xml is as in the tutorial. Below is a part of the stack trace:
Is there maybe an issue with Tomcat 5.2.23? It does not look like
anybody else on the list had this issue so it looks like a configuration
issue on my side, but I can't understand why jetty has no problem. I can
live with not using tomcat, but would really like the canoo tests to at
least pass.
Thanks
