Ok I figured out a way to make it all work ... The solution ended up being to put all the commons jar files in the root of the ear, and add them to application.xml as java modules. Looks like it was indeed a classloader issue then ... which would lead me to think that this is a bug. No reason why Struts shouldn't be able to do all of the reflection, especially since this is hardly pushing the envelope. Any thoughts?
