Thank you very much for the reply. I should have mentioned on the previous post that I have already looked at this page and was hoping for a clearer explanation of what I should do.
All of the use cases seem to relate to an application and server/default/lib. I just need to set an application to not share classes with the UCL (I think?).
Can anybody verify that what I am saying I need is actually what I need and help me understand what configuration settings are needed? Thank you very much.
