I met the same problem. I solved it with
1) Using XA Datasource
2)Using same data source in every ejb
Hmm - Thank you for your answer.
It seems, that I am in the wrong formum now ...
I am using mysql and I don't know, how to create a XA Datasource with mysql. In docs/examples/jca is only a mysql-sevice.xml, and that didn't describe a XA Datasource.
I will "google" around a little and maybe I will open a new Thread under a new topic in the database topic.
With kind regards,
