When I launch the first persistence example from the mdk by exporting the project in eclipse (I have to work offline, i.e without synchronisation), I always get following error:

I think it comes when there is a getTransactionManager() call.

Do I have to configure something special to make it work ?

Has someone else ever had that kind of error before ?
