this is getting absurd, it's a been a week now, and the site is down
compeletly ,
i'm searching for a problem we've been having about opening multiple XA Data
sources for oracle, (opening the second hands jboss and throws an meta-aware
exception, this happens in jboss 4.2)
all the issues that relate to this problem found in google are in
jboss.orgwhich i cannot enter.

Agreed.
Even though I work for a company with paid support for JBoss EAP
jboss.orgis a crucial resource.

thanks, i've read only half of it and i'll explain why. we had not gotten to
actually recovering from a transaction for simple reason that we are unable
to actually create one. as soon as we begin a transaction, we get 2
different jdbc data sources to oracle under a stateless session ejb, when
we use the 2nd getConnection jboss hangs for a half a minute, and then bombs
with unable to enlist data source exception. we tried to walk though the
debugger and it seems somethings during the lock of a transaction, (we used
jboss 4.2.0 which uses jbossjta 4.2.3 sp3 which we didn't have the source
code for, so now we are trying jboss 4.2.3 which uses jbossjta 4.2.3 sp7
which we do have sources for)
before the exception occurs we see 2 warnings from arjuna i18logger about
multiple threads, it seems the transaction is aborting (but never got to the
code that actually aborted it).
the same code worked btw on websphere 6.1
i've seen somewhere that you could use a property called something like
allowMultipleResources in jbossjta.properties file , but that didn't work as
well.
this reminded me of the case in jboss 3.2.5, we used spring 1.2.8 to get jta
transaction, but each time we actually got a transaction it was already
"dead" because of a time out,even though we just got it from begin
transaction method.

If you're getting the multiple last resources message, then you're not
using XA resources. The allowMultipleLastResources setting is a very
dangerous thing to use and I would not recommend enabling it.
All that said, I don't understand why there'd be any long timeouts with
all of this....

no getting multiple resource message, but exactly the warnings he
http://www.jboss.org/feeds/post/transaction_timeouts_and_ejb3_jpa was
getting, ("invoked while multiple threads active within..") but i have no
idea why it's aborting the transaction, maybe because the 2nd getConnection
takes somewhat longer (don't know why, this could be the real problem,)
