I would suggest amending the following text above:

If a durable subscription is being used, then JMS requires that subscriptionName be set. In the case of a MDB the subscriptionName is normally given a name unique to the MDB, to distinguish it from other MDBs and other applications subscribed to the same topic. It is therefore proposed that the EJB specification state that if the subscription is durable and subscriptionName is not set then the container will automatically set subscriptionName to the name of the MDB.

Reopening to update the spec for UniqueMDBName. java:comp namespace is shared in a WAR file, so the current thinking is to use a new method on MessageEndpointFactory. When the API is added in JCA MR, EJB spec needs to be updated.

Adjusted to match the latest JMS spec (including subscription scope removal)

Could you please clarify what must happen, if a durable subscription is specified but subscriptionName is not specified? Is the MDB container required to set a unique subscriptionName?

Another question, depending on the response to the above. May the MDB container set a unique subscriptionName, if the subscriptionName is not provided?

Thank you,
Scott
