jms and transaction

[yxyang]

Hello,

What will happene if i let the onMessage() of a MDB with transaction required attribute? In my case, I test in a MDB , its onMessage method calls a sesson bean's method which will throw an exception. So, i expected that a jms message will be left in the queue because of the failure of the onMessage call. However, i cannot find this message. The queue depth is equal to 0.

The default attribute for MDBs is NotSupported are you sure you have Required?

You shouldn't throw an exception from onMessage() you should do

try
{
}
catch (Throwable t)
{
messageDrivenContext.setRollbackOnly();
}

Most likely you will see an error saying there is no transaction when you try to do this.

If following is done, whether the message will be put back into the queue?

try
{
}
catch (Throwable t)
{
messageDrivenContext.setRollbackOnly();
}
