Re: ClassNotFound Exception with Struts Action
hi Tom,
it's not obvious what your problem could be.
To find out the classpath being used by your app server, you should put
an echo in your app server's batch file at the appropriate point, i.e.
just before it calls javac.
However app servers generally don't include the webapp directories in
the classpath that java uses. It should all be internal.
A frequent error is the spelling. It's case-sensitive.

Re: ClassNotFound Exception with Struts Action

Hi Adam,
Well the problem was basically a lot more trivial. I use JBuilder Enterprise
to build my apps. It has a facility called 'Refactoring'. You can rename
classes, packages etc. and it should rename all references of the object you
rename. It does all the Java things but NOT the XML stuff. So I renamed my
action class but the action mapping in the XML file containing the struts
configuration was not changed! Thats why the class could not be found.
Since I could still not figure out, how to configure JBuilder to write a log
file when tomcat runs in its debugger, I just saw it, when running a
deployed version.

Thought we were on the struts-user list. For app server, read 'tomcat' :)
