Hi,
Does the MQSeries classes for Java(MQ Base Java) and MQSeries classes for Java Message Service(MQ JMS) use the 13 Message Queueing Interface(MQI) calls internally to request the services from the Queue Manager...??
--Thanks

The MQSeries Base Java classes use JNI to jump from java over to the C MQI libraries. Whether they jump into the regular APIs or some sort of hybrid isn't really discussed anywhere.
When using a client connection, the Base classes connect directly to the listener rather than JNI'ing to C and then over to the listener.
JMS is a different kind of beast and you don't have the one-to-one kind of mapping between JMS calls and MQI calls. |

| I would say that the answer depends. You use them when you need to. If you are using JMS, you would probably never do it since it would be an extension from the standard and make your code not portable. What are you trying to do? |
