XA transaction -- Linux v Windows

Hello List:

I have an application running in Glassfish using the 9.3-1102 JDBC 41
driver against pgsql 9.3. The install on Linux (Ubuntu) is installed using
the default configuration. Everything runs smoothly.

I installed pgsql 9.3 on my Windows 8.1 workstation (again default install)
but I get errors similar to:

Warning: JTS5031: Exception [java.lang.RuntimeException:
org.postgresql.xa.PGXAException: Error preparing transaction] on Resource
[prepare] operation.
Warning: JTS5068: Unexpected error occurred in rollback
org.postgresql.xa.PGXAException: Error rolling back prepared transaction
at org.postgresql.xa.PGXAConnection.rollback(PGXAConnection.java:418)

Caused by: org.postgresql.util.PSQLException: ERROR: prepared transaction

does not exist
[snip]

Are there any configuration changes required on the Windows version or with
the driver to allow XA transactions?

Thanks,
Dennis
