The Java solution to application integration in a heterogeneous environment is the J2EE Connector architecture. The architecture provides a standard way to connect to legacy and non-Java systems. As you will learn, the architecture enables EIS providers to create a single resource that permits any J2EE application server to access the EIS. In addition, the architecture defines a standard API that allows you to program against any supported EIS by using a standard set of API calls.
Today's lesson discusses and uses version 1.5 of the Connector architecture.
Overview of the Architecture
The J2EE Connector architecture defines two categories of contract—system and application.
The system contract defines the relationship ...
