Java Business Integration

Last updated

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.

Contents

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:

  1. In-Only: A standard one-way messaging exchange where the consumer sends a message to the provider that provides only a status response.
  2. Robust In-Only: This pattern is for reliable one-way message exchanges. The consumer initiates with a message to which the provider responds with status. If the response is a status, the exchange is complete, but if the response is a fault, the consumer must respond with a status.
  3. In-Out: A standard two-way message exchange where the consumer initiates with a message, the provider responds with a message or fault and the consumer responds with a status.
  4. In Optional-Out: A standard two-way message exchange where the provider's response is optional.

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. [1]

JBI implementations

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.

Java EE SDK also includes the JBI runtime and a BPEL orchestration engine.

Oracle claims its Fusion Middleware comes with JBI implementation. [ citation needed ]

TIBCO ActiveMatrix Service Grid provides a service container framework, based on the JSR 208 and SCA specifications (Service Component Architecture), allowing service containers (Java, Java EE, .net, BPEL) to be added as needed, as composite applications on a common foundation.

Jakarta Enterprise Beans is one of several Java APIs for modular construction of enterprise software. EJB is a server-side software component that encapsulates business logic of an application. An EJB web container provides a runtime environment for web related software components, including computer security, Java servlet lifecycle management, transaction processing, and other web services. The EJB specification is a subset of the Java EE specification.

The Jakarta Transactions, one of the Jakarta EE APIs, enables distributed transactions to be done across multiple X/Open XA resources in a Java environment. JTA was a specification developed under the Java Community Process as JSR 907. JTA provides for:

The Jakarta Messaging API is a Java application programming interface (API) for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem, that can be used to facilitate the sending and receiving of messages between software systems. Jakarta Messaging is a part of Jakarta EE and was originally defined by a specification developed at Sun Microsystems before being guided by the Java Community Process.

<span class="mw-page-title-main">Jakarta EE</span> Set of specifications extending Java SE

Jakarta EE, formerly Java Platform, Enterprise Edition and Java 2 Platform, Enterprise Edition (J2EE), is a set of specifications, extending Java SE with specifications for enterprise features such as distributed computing and web services. Jakarta EE applications are run on reference runtimes, that can be microservices or application servers, which handle transactions, security, scalability, concurrency and management of the components it is deploying.

Enterprise service bus Communication system in a service-oriented architecture

An enterprise service bus (ESB) implements a communication system between mutually interacting software applications in a service-oriented architecture (SOA). It represents a software architecture for distributed computing, and is a special variant of the more general client-server model, wherein any application may behave as server or client. ESB promotes agility and flexibility with regard to high-level protocol communication between applications. Its primary use is in enterprise application integration (EAI) of heterogeneous and complex service landscapes.

Jakarta Connectors is a Java programming language tool for connecting application servers and enterprise information systems (EIS) as part of enterprise application integration (EAI). While JDBC is specifically used to connect Java applications to databases, JCA is a more generic architecture for connection to legacy systems. JCA was developed under the Java Community Process as JSR 16, JSR 112 and JSR 322.

GlassFish is an open-source Jakarta EE platform application server project started by Sun Microsystems, then sponsored by Oracle Corporation, and now living at the Eclipse Foundation and supported by Payara, Oracle and Red Hat. The supported version under Oracle was called Oracle GlassFish Server. GlassFish is free software and was initially dual-licensed under two free software licences: the Common Development and Distribution License (CDDL) and the GNU General Public License (GPL) with the Classpath exception. After having been transferred to Eclipse, GlassFish remained dual-licensed, but the CDDL license was replaced by the Eclipse Public License (EPL).
