You need to call the close method on the Connection which should eventually call the method on the ManagedConnection which in turn should call the ConnectionEvenListerner to close the connection . This goes as per the specs , would it be possible for you share the code I can have a look at how you are doing this ? I don't have knowledge about the bespoke protocol but that should not create any hindrance in understand the skeleton JCA implementation which you would be doing .
