What exactly did you do to "make PGXAConnection serializable"? If you
just add "implements Serializable", you'll get an
NotSerializableException when you actually try to serialize it.

According to that, you need to provide an implementation of
com.arjuna.ats.jta.recovery.XAResourceRecovery. Apparently there's a
simple implementation that looks up the XADataSource implementation with
JNDI. See JBoss Transaction API Programmers Guide, chapter 4, title
"Shipped XAResourceRecovery implementations".
I'm surprised Arjuna/JBoss doesn't just connect to every database listed
in JNDI, or at least all those that were used in the transactions that
need recovery. That's what other app servers do, I believe.
