Two connections in one transaction?

I'm using a stateless Session Bean as a facade to some Entity Beans. All transactions are managed by the container.
I want to have access to two connection pools within one transaction. I'm using a DB2 with the and an InstantDB with the org.enhydra.instantdb.jdbc.idbDriver. I know that it must be possible as these drivers support XA-Transactions.
But with my setup I'm getting a java.sql.SQLException that there cannot be two connections within one transaction. Can anyone give me some hints how to setup my JTA properties for this scenario?
Thanks in advance
It is sorta covered in the JavaRanch Style Guide.
