This article describes and compares various options for integrating mainframe applications with new applications--primarily Java™ and J2EE applications--including both point-to-point and Enterprise Service Bus (ESB) based integration options.

Summary

Senior developers, IT architects, and project managers frequently need to integrate existing mainframe applications with new applications that don't run necessarily run on the mainframe. Examples of mainframe applications include CICS and IMS transaction applications; modern applications include J2EE applications and some C++ applications. Modern applications would usually reside on a system other than a mainframe system, such as Windows® or UNIX®, but they could also reside on the same or a separate mainframe system. Because IBM offers a variety of options to integrate your applications, choosing the right approach for a given scenario might seem like a difficult job. This article can help you make the right choice for your environment by reviewing and presening the various choices and their differentiating features in one article.

This article is for senior developers, architects, and mid-level mangers who need to make decisions related to using the various technologies available for integrating mainframe applications. Some knowledge of Java, J2EE, messaging, and transportation protocols is needed.
