Re: [eclipselink-users] EclipseLink problems with Postgres 9.1 
I use JTA, JBoss container does all the tx managment, I use mix of CMT
and BMT where appropriate. As you can see I did not list any
persistent classes as some documentation might suggest - everything
worked as expected.

Much appreciated,
Vladimir
