TCP/IP JCA Adapters Contrasted With TCP/IP eWay Adapters

JCA Adapters:

• Are used from within Java EE 5 applications (EJB 3.0) to get connectivity with the external systems.

• Have no dependency on the Java CAPS Repository.

• Allow EJB applications (equivalent to Java Collaboration Definitions) to use the adapter's fine-grained API calls inside business logic

• Are globally deployed and shared among more than one Java EE application.

• Can share a common pool with a fixed set of properties.

• Can easily have configuration properties changed after the project has been built and deployed.

• Use the same code base as eWays.

eWay Adapters:

• Are used in Java CAPS Repository-based projects to get connectivity with the external systems.

• Are usually dependent on OTDs that provide fine-grained API for use in Java Collaboration Definitions where business logic is implemented.

• Are embedded within the .EAR file; the scope of each eWay at runtime is limited to that EAR only.
