As this is regarded to cmp/cluster implementations, i thought this 
questions should be posted here :

1 - How are two-phase commit implemented in JBoss? Does it takes 
advantage of oracle implementation of this feature?

2 - When there are a transaction not completed at one node of cluster, 
and it fails, does the client have to rerun the transaction, or the 
transaction is gotten and completed by other node?

The problem is that DBA's here (a bank) knows very well how the 
transaction is done and how to return to a consistent point if there is 
some problem and they are worried about using CMP becouse much of work 
is done behind the scenes. How could I convince them that clustered 
JBoss-CMP is secure and will not be a problem when managing data.
