connector/txmanager enlistment failure

[Florent Guillaume <fg...@nuxeo.com>]

Hi,

I'm wondering why no exception is raised in the following case:

- TransactionEnlistingInterceptor.getConnection calls
transaction.enlistResource(xares)
- TransactionImpl.enlistResource calls xaRes.start
- there's an XAException during start()
- TransactionImpl.enlistResource catches this, sets the transaction
rollback only, and returns false
- TransactionEnlistingInterceptor.getConnection does not check the
return value of transaction.enlistResource and returns

In the last step I would expect that if false is returned,
TransactionEnlistingInterceptor.getConnection would raise a new
ResourceException for instance (as is the case for other error cases).

Thanks,
Florent

So what happens now is that the client requesting the connection gets one, but it's transaction status is "rollback only"

and what you are suggesting is that the client should get a ResourceException?

I haven't looked at the relevant specs lately, do you know if anything about this situation is described?  Do you know what other connector/tm implementations do?

thanks for the sharp eyes :-)
