Your test case worked as you described.
I send you an ear app which you can deploy in a jboss-4.2.x, Postgresql must be defined as <jndi-name>pgsql</jndi-name>
in xa-datasource inside jboss's deploy dir.
You can go to the app by hitting: http://localhost/xabug and looking at the directions there.
Again, thanx for caring, and lets see if you can figure smth out off this.
