Tim, Basically, I did two things (see attached diff) 1. In connector/src/main/org/jboss/resource/adapter/jdbc/xa/XAManagedConnection.java I added caching of XAResource 2. In server/src/main/org/jboss/tm/XidImpl.java I changed getGlobalTransactionId() and getBranchQualifier() to always return 64-byte arrays. Devid reinterpreted this change slightly, he added xid factory which can be configured to create correct xids (I mean, correct from oracle's point of view).

Re: [JBoss-user] XATxConnectionManager with Oracle?
Thanks for that. Basically I checked out the 3_0_0 branch, and built it, and couldn't even get my non xa application (which works on 3.0.0 final release) working - I was getting NoSuchMethodErrors from the ear deployer. I guess I was doing something wrong and it was late and I was in a rush so I'd thought it might just be easier to patch the files directly onto our working codebase, hence the question.

Re: [JBoss-user] XATxConnectionManager with Oracle?
This may be a little out of the topic, but I thought it won't hurt to have a look too: In my attempts to write a resource adapter I've noticed a strange behaviour (I also posted some messages on this forum about it): When the getConnection is called for the first time, everything works fine. For subsequent calls, the associateConnection() was called by the connection manager befor getConnection being invoked as if a handle to my previos connection was being held over method boundaries (I mention that I closed all connection handle in the same method though). Briefly, the cause was this: when a close() is sent, the managed connection calls close() too. Here a CONNECTION_CLOSED event is sent to the cm listener. JBoss expects the connection handle with the event too (for that use setConnectionHandle for an event), otherwise the connection handle is not properly unregistered by CachedConnectionManager and consequently next run it will appear as a connection held over method boundaries.

Thanks for your work on this. Please post the results when you are satisfied. IMO the entire xa wrapper needs replacing which I unfortunately won't have time for soon. I'm not sure if associateConnection can be implemented easily. You can avoid it being called if you always close connection handles before calling other ejb methods (through home or remote interfaces) (and do not hold connections over method boundaries).
