Re: Eclipse, log4j, etc.

The problem may not be directly with the BeanUtils class, but rather a  
class it imports. For all of our installations, we have the following  
commons jars in every webapp's WEB-INF/lib directory:

commons-beanutils
commons-collections
commons-lang
commons-logging

Actually, that's a bit of a lie. For lang, collections, and logging, we  
put them in Tomcat's common/lib directory so that they don't have to be  
everywhere.

<rant>
This is the big problem with using anything in Jakarta commons IMHO:  
using anything requires using almost everything. Since that's the case,  
they need to just package it as one big jar, because the parts aren't  
really separable from the whole. And the Velocity team is actually  
introducing more dependency on commons in the next release, much to my  
dismay.
