Struts jar
This is driving me insane, first up I had the classic
java.lang.NoClassDefFoundError. Trolling through the archives I found that I
must not have struts.jar in the lib directory of the webserver only in the
WEB-INF directory of the application.
After a few days it goes belly up once again, I cannot figure it out I go
searching my entire machine for struts.jar I find a copy in netbeans/lib/ext
(go figure). I nuke the offending jar. Reinstall resin (the webserver), I
wouldnt run, and then recompile the app. It worked until today, now the
problem has returned.
I have nuked every instance of struts.jar on my machine (except of course
the one in the application lib directory). Everything compiles but it will
not run. The irony is that if I drop one of the war files in the webapps
directory it works (I think this is just to make me feel worse).
The current error is
java.lang.NoClassDefFoundError: org/apache/struts/util/GenericDataSource
but if I take out the load-on-startup it will just be anything from the
org/apache/struts package

Thanks for the help. Keith yes it is a right royal pain in the Java.
I have fired up Tomcat and it works with Tomcat (still wont work with Resin
however), so I am continuing development on Tomcat, knowing full well that
it is to be deployed with Resin as the web server.
As Dr Smith would say, "Oh the pain".

can't help you mate - but full sympathies.
I reckon the laws of cause & effect got a bit fuzzy on the server side.
This multiple class loaders thing is a real pain in java. I reckon it's a
problem in the design of the language. It creates a mighty trap that catches
people again & again. We are in the pioneering days of web development so
much
pain to be endured.
When my app broke but the examples work try:-
1 - copy struts-stub to a new name.
2 - restart the server to deploy it.
3 - move my app into this new app.
It would work. That way I never really found out what was wrong - but never
wasted lots of time learning to be a server guru.
good luck. - Keith
