Hi,

We have clients written in C++ using the C++ MQ API and server code listening and responding using the MQ JMS API. No problems as long as we set the targetClient. Can the MQ Series pub/sub capability be used by both clients?? Specifically, we want to be able to publish to a topic using the Java JMS API and have subscribers which are using the C++ API? Is this possible? Any problems doing this? I am assuming the JMS pub/sub is built on top of the MQSeries pub/sub "under the covers".

Yes. JMS pub/sub uses the RFH2 just like 'regular' PUB/SUB, as I understand it.

Your C++ applications will have to be modified to be aware that there is an RFH2 in the message.

As Jeff says, there is no problem with this, and by setting targetClient to
JMSC.MQJMS_CLIENT_NONJMS_MQ, this indicates that no MQRFH2 field is to be produced.
