Java Business Integration

Java Business Integration (JBI) is a specification developed under the Java Community Process (JCP) for an approach to implementing a service-oriented architecture (SOA). The JCP reference is JSR 208 for JBI 1.0 and JSR 312 for JBI 2.0. JSR 312 was removed from the JCP balloting process on 17 Dec, 2010 by the submitters without being accepted.

JBI is built on a Web Services model and provides a pluggable architecture for a container that hosts service producer and consumer components. Services connect to the container via binding components (BC) or can be hosted inside the container as part of a service engine (SE). The services model used is Web Services Description Language 2.0. The central message delivery mechanism, the normalized message router (NMR), delivers normalized messages via one of four Message Exchange Patterns (MEPs), taken from WSDL 2.0:

To handle functionality that deals with installation, deployment, monitoring and lifecycle concerns amongst BCs and SEs, Java Management Extensions (JMX) is used. JBI defines standardized packaging for BCs and SEs, allowing components to be portable to any JBI implementation without modification.

JBI defines standard packaging for composite applications: applications that are composed of service consumers and providers. Individual service units are deployable to components; groups of service units are gathered together into a service assembly. The service assembly includes metadata for "wiring" the service units together (associating service providers and consumers), as well as wiring service units to external services. This provides a simple mechanism for performing composite application assembly using services.

The following open-source software JBI based ESB implementations are available:

The following ESBs are certified by the JBI/JSR 208 TCK: Open ESB and Petals ESB.

In addition, the Project GlassFish open-source Java EE application server comes with the JBI runtime from the Open ESB project.
