I got OpenJPA to run with my JPA code.  So we're looking real good.

OpenJPA and the Geronimo JPA spec jar weren't happy.  Our JPA jar had  
some bad signatures and was missing a few exception classes.  I fixed  
those and managed to get OpenJPA to compile and run with our JPA jar  
rather than the CDDL version they use.

For me its:
  - Still missing the some JNDI stuff Dain is working on (mentioned  
earlier in the thread).
  - Need the plugin goop

But when that is there, this should run for ejbs or servlets in 1.1.1  
and maybe 1.1 (should work).

I'm sure we can figure something out.  I'll give it some more thought  
tomorrow, time for bed now....zzzzZZZZ
