Abstract

Systems and methods for providing interoperability of systems are provided. One embodiment may be seen as instantiating a server in a container having instances of Enterprise Java™ Beans (EJB), and accessing the EJB through the local interface of the EJB. Since the EJB is accessed from within the container, the need for translation of messaging protocols at a bridge is removed. The server components are provided access to the EJB logic through the local interface of the EJB.
