Both are type 4 (ie thin) drivers, the XA version means it supports distributed transactions ie it can join in with transactions from other databases or other transactional protocols using two phase commit (2PC)

XA database drivers are useful in EJBs since the transaction demarcation can span several types of transaction and you still need to provide an all-or-nothing guarantee.
