OpenESB


OpenESB is an open source Java Business Integration (JBI) standard-centric Enterprise Service Bus, originally from Sun Microsystems, now Oracle Inc. 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 or can be hosted inside the container as part of a service engine. The services model used is Web Services Description Language (WSDL) 2.0. Open ESB consists of a runtime, a design time, and a management console. The runtime consists of a lightweight JBI core and several components. OpenESB comes with several components for data transformation, orchestration, and connectivity. There is support for HTTP and web services, JMS, databases, MQ Series, SAP, IMS, HL7, and others.
