JTA transaction on 2 datasources....

Hi all,

I've got a problem using two cmp entity beans of different containers in
one transaction. The containers have different  datasources. A session
bean starts the transaction. The isolation level of all beans is
TRANSACTION_REPEATABLE_READ. Both entity beans have the transaction
attribute TX_SUPPORTS. The invoked method of the session bean has
TX_REQUIRES_NEW. Always the session bean wants to create an entity bean in
a different container an exception occurs. The jdbc driver is
"com.ibm.db2.jdbc.app.DB2Driver" and jta is enabled. If both containers
have the same datasource (and the tables are moved to the other
collection) all works fine.

Has anyone an idea why the JTA two phase commit doesn't work?


Thanks

Mattias
