HELP: no further JDBC access is allowed within this transaction

[Ming Xu]

Could anyone give me some comments on this exception? In our design, one
session bean is used to access some entity beans. Each bean will ask for a
db connection from a pool when it needs data from database, and then return
the connection back to the pool immediately after accessing database.

The transaction attribute for session bean is TX_REQUIRES_NEW. and for
entity bean is TX_REQUIRED.

java.rmi.RemoteException: The coordinator has rolled back the transaction.
No further JDBC access is allowed within this transaction.
