Client Compatibility

Message Queue 3.7 UR1 message brokers and Java clients (applications and components) are two-way compatible with those from Message Queue 3.0.x, 3.5, or 3.6: that is, a Message Queue 3.7 UR1 broker will support a Message Queue 3.0.x, 3.5, or 3.6 Java client, and a Message Queue 3.7 UR1 Java client can connect to a Message Queue 3.0x, 3.5, or 3.6 broker. Expanded Message Queue 3.7 UR1 capabilities are unavailable in such cases, however.

C client programs cannot connect to a Message Queue 3.0.x broker; they are supported only by Message Queue 3.7 UR1 brokers or by Message Queue 3.5 and 3.6 brokers running with a trial or enterprise license.
