You will probably want to use Tyrex for now. Both the jboss tm and tyrex can use XAResources from Oracle and other xa capable resource managers, and follow the xa 2pc protocol (at least as far as it is comprehensible). However, the jboss tm does not log transactions, so there is no automated recovery. The jboss tm also does not currently support distributed transactions, although this should be coming soon in jboss 4. If you have a homogeneous deployment this would not be relevant, however.
