Howdy!
I'm new to this list and want to start off saying that digging into
jBoss has been fun stuff! Thanks to all involved for bringing this
product along!!
I have a container managed transaction (CMT) session bean that does a
little money transfer demo. In the transfer method I'd like to roll back
if the "from" account will be < 0.00. I think I should be able to do
this by calling context.setRollbackOnly() but when I use that I get an
error:
[BankBean] javax.transaction.RollbackException: Already rolled back.
If I take the context.setRollbackOnly() call out
InsufficientBalanceException gets thrown but no rollback happens and the
account gets a negative balance.
Could someone please give me a clue?
TIA,
Boz
Here's the whole method:..........................
public void transferToSaving(double amount)
throws InsufficientBalanceException // extends Exception
{
checkingBalance -= amount;
savingBalance += amount;
try {
updateChecking(checkingBalance);
if (checkingBalance < 0.00) {
context.setRollbackOnly();
throw new InsufficientBalanceException();
}
updateSaving(savingBalance);
} catch (SQLException ex) {
throw new EJBException
("Transaction failed due to SQLException: "
+ ex.getMessage());
}
}
Here's a snip of the ejb-jar.xml:...........................
