Re: [Mav-user] Eclipse, log4j, etc.

[Todd O'Bryan]

I removed commons-beanutils.jar from the Tomcat classpath (which you  
can set in Eclipse using the Preferences pane) and was able to compile.  
It also then ran the Log4jInit code someone suggested I create...of  
course, only after producing the warnings that code was meant to stop  
from appearing in the first place.

And now I can compile, but I get the same NoClassDefFoundError in my  
webapp when I try to access that page.

If ever there was a need for a better mousetrap, we're seeing it...

AFAICS, Tomcat (at least 4.1.18) has its own commons-beanutils.jar in

its server/lib. It could conflict with the one you added to Tomcat
classpath.

The jars in Tomcat's server/lib directory are not visible from
webapps.
However, the jars in common/lib and shared/lib are.


That's it. But exception is thrown by Catalina itself, and not a  
webapp.

So if this: "add commons-beanutils.jar ... to the Tomcat classpath"
means adding commons-beanutils.jar to CLASSPATH in catalina.bat, or
changing CLASSPATH environment variable, or smth similar, a conflict
could be the case. However exception is strange, and the reason could  
be
anything else.

exception from Todd's letter:
