[jboss-user] [JCA/JBoss] - Problem with RA & inbound transaction -> MDB -> CMPs

[matterbury]

I have an EJB of 5 entity beans and 5 corresponding session beans. The only methods are to create an instance of an entity (it is a toy test case). All 5 entities must be created together due to FK constraints (each is created by invoking the 'create' method on the corresponding session bean). It works fine when invoked in a UserTransaction from a remtoe Java client program.

I also have an RA and MDB that implement JCA inbound transactions. In response to requests, the RA creates an XID and creates an execution context in which the MDB is invoked, which invokes the EJBs methods.

At the end, the RA tries to end (+ prepare + commit) the transaction, but this is failing because arjuna tries to update one of the created records but cannot find it, despite it logging earlier that it INSERTed it and that it found it using SELECT (I hand check each FK constraint in the SB's create method).

AFAIK this means that the end is being executed in the wrong thread/context as otherwise it should find it (again).

So, my questions are: is there any other reason the update could fail? how might I track down what's going wrong (I have turned on arjuna's DEBUG but it doesn't give enough detail for this)?

FWIW, the actual exception is:
