Re: Classpath Issues with Log4J?

Ok, the data provided does really help me.
Jetty doesn't contain a log4j file and cargo doesn't reference any
org.apache.log4j classes. I am guessing the webapp contains the log4j
jar within its web-inf/lib directory and the webapp tries to reference
log4j and the error gets thrown? Any more data you can provide?
 

Absolutely!  I'll be more than happy to give you tons of information.  I just didn't want to flood the list, initially.  :-)

Yes, the log4j jar is in WEB-INF/lib.  It is version 1.2.14.  It appears to me that the exception is thrown by Jetty as it begins the process of initializing the web context for the embedded application.  (I am trying to run this in embedded mode.)  A larger chunk of the exception stack is included below.  One of the first things that happens when the context initializes (in our app) is that we initialize logging the way we want it to work.  However, I don't see that class/method in this stack.  So, I'm not sure if we've even gotten that far along, yet.

If I can provide anything else, please just let me know.  It might take a bit of time - I'm working on other things, right now, so have to recreate the environment that causes this exception.  It's easy to create, though, and I don't mind helping track down a problem, if I can.
