I've had a similar problem using Orion as the application server and I've
been trying to solve it for a while with no luck.

I know the required jar's are in the classpath because it can find the
classes with no problem, however when I try to load a resource from the same
jar it can't find it.  Trying to figure out the class loading of a J2EE
server is a nightmare.  FYI - The only way I was able to solve the problem
up till now was either to put the classes in the server's classpath, or to
put the jar's in the the WEB-INF/lib directory if they are only used by the
web application (though this doesn't solve the problem when it comes to
MBean usage.)
