Orion only supports a partial ejb2.0 spec - an older one at that. I don't believe it supports many-many out of the boxmore ejb2.0 coming up! --- Christoph Sturm [EMAIL PROTECTED] wrote: Hi all!

Hi. You currently need to have your CMR fields as cmr-field in ejb-jar.xml. That should fix your problem.

ejb 2.0 relations in orion 1.4.3 broken ?
The current ATM example uses EJB 2.0 definitions of ont-to-many relationships (account_owner - account) . When I deployed it on orion 1.4.3 it workes quite well until I added some accounts. After shutting down orion and re-login all accounts are lost. A quick look into the hsql file (.script) revealed that there was no INSERT statement for the ACCOUNTOWNER_ACCOUNTS table at all, where the set-mapping between the AccountOwner and Account bean should happen. Any idea, or maybe an example how I can work around it by using orion-ejb-jar.xml ? Thank you in advance, Axel.
Re: ejb 2.0 relations in orion 1.4.3 broken ?
EEK! Axel, I have not yet tried to verify this and am not dure how to work around it, but if you are sure please Bugzilla it as soon as possible. I was just reviewing the bug list and saw that Magnus seems to be making excellent progress in cleaning up the EJB 2.0 persistence manager related bugs. Maybe if you get this one logged quickly, he can throw a fix in for it.

RE: ejb 2.0 relations in orion 1.4.3 broken ?
Title: RE: ejb 2.0 relations in orion 1.4.3 broken ? Hi Alex, well, the ATM needs to be updated a bit. Its descriptor is stuck somewhere between 1.1 and 2.0 during that it has been updated as the 2.0 implementation progressed. Hopefully, I will get time to do this this weekend.
