Release Note : WSO2 Enterprise Service Bus 3.0.0

May 3rd 2010

The WSO2 ESB offers a new lean approach to creating an SOA by adding monitoring, management and virtualization to your existing service interactions. Its innovative design leads it to be one of the highest performance, lowest footprint, and widest interoperability integration systems available.

WSO2 ESB 3.0.0 is developed on top of the revolutionary WSO2 Carbon platform an OSGi based framework that provides seamless modularity to your SOA via componentization. This release also contains many new features and a range of optional components (add-ons) that can be installed to customize the behavior of the ESB. Further, any existing features of the ESB which are not required to your environment can be easily removed using the underlying provisioning framework of Carbon. In brief, WSO2 ESB can be fully customized and tailored to meet your exact SOA needs. You can download this distribution from New Features in this release

Other Key Features
  • Proxy services - facilitating synchronous/asynchronous transport, interface (WSDL/Schema/Policy), message format (SOAP 1.1/1.2, POX/REST, Text, Binary), QoS (WS-Addressing/WS-Security/WS-RM) and optimization switching (MTOM/SwA).
  • Non-blocking HTTP/S transports based on Apache HttpCore-NIO for ultrafast execution and support for thousands of connections at high concurreny with constant memory usage.
  • Built in Registry/Repository, facilitating dynamic updating and reloading of the configuration and associated resources (e.g. XSLTs, XSD, WSDL, Policies, JS configurations ..)
  • Easily extendable via custom Java classes (mediator and command)/Spring configurations, or BSF Scripting languages (Javascript, Ruby, Groovy, etc.)
  • Built in support for scheduling tasks using the Quartz scheduler.

  • WS-Security, WS-Reliable Messaging, Caching & Throttling configurable via (message/operation/service level) WS-Policies
  • Lightweight, XML and Web services centric messaging model
  • Support for industrial standards (Hessian binary web service protocol/ Financial Information eXchange protocol and optional Health Level-7 protocol)
  • Enhanced support for the VFS (File/FTP/SFTP), JMS, Mail transports with optional TCP/UDP transports and transport switching among any of the above transports
  • Support for message splitting & aggregation using the EIP and service callouts
  • Database lookup & store support with DBMediators with reusable database connection pools
  • WS-Eventing support with event sources and event brokering
  • Rule based mediation of the messages using the Drools rule engine
  • Transactions support via the JMS transport and Transaction mediator for database mediators
  • Internationalized GUI management console with user/permission management for configuration development and monitoring support with statistics, configurable logging and tracing

  • HTTP GET requests performed on an endpoint that has a trailing '/' character, do not work properly
  • SOAP tracer does not work when the message relay is activated
  • The sequence editor and the built-in XML editors do not work properly on Google Chrome
