Is it possible with Glassfish to have a persistence unit that several ejb jars in an ear can share? I've tried a bunch of combinations with persistence.xml in various places: inside the ear itself, inside a "persistence module" ejb jar by itself, etc. But I can't get it to work. Has anybody successfully done this that can explain how? I've done a bunch of googling and haven't found the right clue.
I have successfully done this with JBoss 4, but the same configuration of ear and persistence jar doesn't work in Glassfish [v2.1 (9.1.1) (build b60e-fcs)].
