Can anyone explain the underlying technical reasons why EJB does not permit
transactions to be demarcated via java.sql.Connection? I know the "what",
but don't have a full understanding of the "why".

Laurel,
You are absolutely right - I was ranting about the XA & distributed
transactions and meant to discuss the java.sql.Connection class and the
UserTrasaction in the same breath, but somewhere along I kinda forgot the
UserTransaction.
The EJB 1.1 spec does state that a BMP enterprise bean cannot call the
Connection.commit or rollback while in the _midst_ of a transaction. or for
that matter even a setAutoCommit.
