[jsr220orm-dev] Fwd: broken persistence :-(

[Scott Menor <smenor@xxxxxxxxx>]

Hello -

I'm  migrating from Hibernate to EJB persistence and was very excited  
to find your project

I've been trying to get the JSR220 M2 plugin to work since august.  
Unfortunately, I've have had a horrible time trying to get it to  
work, so far.

I've followed the online tutorials ( http://www.eclipse.org/jsr220orm/ 
flash_menu.html ) as closely as possible but keep getting exceptions  
like the one at the end of this message.

To make things more frustrating, I actually had the hibernate backed  
EJB persistence working for about 10 minutes this afternoon so I know  
that it *can* work. Unfortunately, I started getting an error about  
not being able to find the par file (even though the path in the  
error actually pointed to it) .

I've reinstalled Eclipse, Hibernate and JSR220 M2 5-6 times on my  
notebook (Mac OS X 10.4.2 / Java 5 ) and 2-3 times on two different  
windows XP machines. The only time a call such as this -

EntityManagerFactory entityManagerFactory =  
Persistence.createEntityManagerFactory("argh");

have worked for me was (briefly) this morning and I have no idea at  
all why it started working or why it stopped again.

I can't offer a procedure to reproduce the issue other than to  
duplicate the procedure offered in the above tutorial.

If you can offer any suggestions, I'd really appreciate them and  
would be happy to give any additional information you may require.

I realize that it's only a milestone release but am hoping that  
someone could help me out (and, ideally, that whatever issues I'm  
facing can be fixed before the final release).

Thanks and best regards,
Scott
