Using IBM MQ classes for JMS in a CICS Liberty JVM server

From IBM® MQ 9.1.0, Java programs running in a CICS® Liberty JVM server can use the IBM MQ classes for JMS to access IBM MQ.

You must be using an IBM MQ 9.1.0, or later, version of the IBM MQ resource adapter. You can obtain the resource adapter from Fix Central (see Obtaining the IBM MQ resource adapter and IBM MQ resource adapter for Jakarta Messaging).

There are two flavors of Liberty Profile JVMs available in CICS 5.3 and later, the types of connection possible to IBM MQ are restricted as follows:

CICS Liberty Standard

The IBM MQ resource adapter can connect to any in-service version of IBM MQ in CLIENT mode
The IBM MQ resource adapter can connect to any in-service version of IBM MQ for z/OS® in BINDINGS mode when there is no CICS connection (active CICS MQCONN resource definition) to the same queue manager from the same CICS region.

CICS Liberty Integrated

The IBM MQ resource adapter can connect to any in-service version of IBM MQ in CLIENT mode.
BINDINGS mode connection is not supported.

For details on setting up and configuring your system, see Using IBM MQ classes for JMS in a Liberty JVM server in the CICS documentation.
