RE: Best practices for shared classloader use?

[Don Asper]

Sorry, I was not clear in my first post.  I want to load the jars containing 
functionality that is common to my web apps using the shared classloader.  I 
anticipate that there can be problems if different versions of the same class 
are on the shared classpath.  I also suspect that any common jars or classes 
will cause a problem if they contain static fields.  Am I correct in this?  Are 
there other problems that typically occur when attempting to share classes?  
What should I watch out for when trying to share functionality between my web 
apps?  Thanks.
