There is a requirement to allow an update on MDB selector to be performed without having to redeploy the application. At the moment the only way to change a MDB selector si to update it's deployment descriptor which will force the redeployment of the whole application. This is not a very practical solution particularly if more than one application is involved. It would have been much more convenient if the MDB container would allow to change the MDB selector without a need to redeploy the application. In this case the end user is prepared to accept any consequences in performance that amy be caused by disconnecting and reconnecting MDB session.
