MuleSource has announced the general availability of Mule 2.1 Enterprise, a new enterprise-class edition of the open source enterprise service bus (ESB), complete with new capabilities and features including premium connectors, support for the Mule RESTpack, and retry policies designed for enterprise deployments.

Mule 2.1 Enterprise is available immediately to MuleSource subscription customers. For a single annual fee, a MuleSource subscription offers a combination of technical support, sophisticated management tools, and reduced total cost of ownership (TCO).

Features available in Mule 2.1 Enterprise include:

Premium connectors - built for high performance and with enterprise-only features, fully certified and supported by MuleSource

• Premium JDBC Connector - support for advanced JDBC functions, such as batch and cursor mechanisms, resulting in over two orders of magnitude (150x) performance improvements for certain use cases
• WebSphere MQ Connector - bi-directional request-response messaging between WebSphere MQ and Mule JMS using native MQ point-to-point, as well as synchronous and asynchronous request-response communications using JMSReplyTo

Mule RESTpack - now supported as part of the core Mule 2.1 Enterprise product, allows developers to create REST-style services, which form the basis for web oriented architecture (WOA), using popular frameworks such as RESTlet and Jersey

Out-of-the-box retry policies - allows creation of self-healing connections, instructing Mule to attempt reconnection based on pre-defined policies, without the need for custom code
