IBM MQ classes for JMS architecture

IBM MQ classes for JMS has a layered architecture. The topmost layer of code is a common layer that any IBM JMS provider can use.

IBM MQ classes for JMS has a layered architecture as shown in the diagram Figure 1. The topmost layer of code is a common layer that can be used by any IBM JMS provider. When an application calls a JMS method, any processing of the call that is not specific to a messaging system is performed by the common layer, which also provides a consistent response to the call. Any processing of the call that is specific to a messaging system is delegated to a lower layer. In the following diagram, the IBM MQ messaging provider is shown in the lower layer, together with two further messaging providers (Messaging provider A and Messaging provider B.)

Figure 1. The layered architecture for IBM JMS providers

A layered architecture fulfills following objectives:

To improve the consistency of behavior of the various IBM JMS providers
To make it easier to write a bridge application between two IBM messaging systems
To make it easier to port an application from one IBM JMS provider to another
