i've dynmically added a XADataSourceLoader MBean during program execution, and i
was testing the behavior if the connection failed. an exception is thrown
inside jBoss, but it isnt' returned to my application. (the exception is shown
below) unless i've missed something, i correctly handle a SQLException in
EMEDBAdapaterEJB.ejbCreate() any ideas why this is happening?
also, what should be the behavior of jBoss is a connection is lost? is there a
built-in recovery mechanism or a facility to add an application level recovery
mechanism?
thanks,
rob
