Java CAPS combines business process modeling and orchestration, convenient interface design, metadata management, and strong development tools—all in a comprehensive platform built on open standards. OpenESB on the other hand, hosts a set of pluggable component containers, which integrate various types of IT assets. These pluggable component containers are interconnected with a fast, reliable, in-memory messaging bus called the Normalized Message Router (NMR) also referred to as the JBI Bus. Fred Aabedi at Sun, then writes about the meaning behind OpenESB becoming part of CAPS:
The merge of the OpenESB framework and some of JBI components into CAPS 5.2 brings exciting new possibilities to both our existing and new customers in the integration, composite applications, and SOA domains. A consolidated runtime environment based on the world class Glassfish platform allows the interoperability of our classic Java EE based components and new JBI based components. This combination is quite powerful and provides a lot of new options to our customers to solve their integration problems and build killer composite applications. Customers realize this ability to leverage existing proven solutions along with leading edge technologies by taking advantage of the Bi-directional Re-use features (JBI Bridge) that allow interoperability between the Java EE and JBI based components. In addition, standardization on the NetBeans 6.0 platform for all of the Java CAPS tooling gives developers a proven and effective platform on which to develop enterprise solutions.
