Hi Jeff! Thanks alot! I see I'm not the only one up at 4:00AM! I really, really appreciate your help with this. I'll look at that right away. In the meantime, I solved the problem minutes before your email arrived. Apparently, Orion does not like for the create() method on the bean class to not set a value for the primary key. I was leaving them set to null, which was causing the NPE. I replicated this in a small, simple sample that does nothing more than have a servlet create an entity bean (in EJB 2.0, of course). Anyhow, I don't know what the scoop on this is. I'm going to review the spec, since I thought that was legal behavior. Then again, anything seels legal at 4:00AM!!! Thanks again!! I'll let you know what I figure out.
