Problem with committing in XA mode

Hi Heikki,

I am facing tx timeout problem when committing certain tx in XA mode
using pure postgre jdbc type 4 driver. The tx is issued/started from
within backend deployed on AS BEA Weblogic 10 MP1.
Ive tried the postgresql-jdbc-8.3-603 jdbc driver, the one bundled with
weblogic and also edb jdbc driver.
In all cases, i see this in db server log:

and this in weblogic log:

--

i.e. weblogic is waiting for the commit and then time-outs.

I've also tried the simple XA example as described in
http://archives.postgresql.org/pgsql-jdbc/2007-06/msg00050.php and it
works lie a charm, the problems are only when weblogic backend is used.

Could this be some XA related postgre jdbc issue?
