Hi Tim, Thanks for the response, the Scheduled Delivery Test came in useful. However, i am still having problems setting the DLQ and RedeliveryDelay. Is there something else i should be setting somewhere in a config file to use these values or somewhere in the code to enable these to be used. Just to fill you in on what i am doing, is that i have an MDB reading messages off a queue, if an exception is thrown i am leaving the JBoss container to deal with the rollback, i am not specifically stating rollback as i do not need to use an XA transaction.
