The WSO2 ESB team is pleased to announce the release of version 4.0.0 of the Open Source Enterprise Service Bus (ESB).
WSO2 ESB is a fast, lightweight and user friendly open source Enterprise Service Bus (ESB) distributed under the Apache Software License v2.0<http://www.apache.org/licenses/LICENSE-2.0.html>. WSO2 ESB allows system administrators and developers to easily configure message routing, intermediation, transformation, logging, task scheduling, fail over routing and load balancing. It also supports transport switching, eventing, rule based mediation and priority based mediation for advanced integration requirements. The ESB runtime is designed to be completely asynchronous, non-blocking and streaming based on the Apache Synapse<http://synapse.apache.org/> mediation engine. WSO2 ESB 4.0.0 is developed on top of the revolutionary WSO2 Carbon platform<http://wso2.org/projects/carbon> (Middleware a' la carte), 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 http://wso2.org/downloads/esband give it a try. *Brand New Features in this Release* - HTTP relay transport - Pure streaming HTTP transport based on Java NIO for ultra fast HTTP routing - Deployment synchronizer - Easily synchronize the configuration across a cluster of Carbon Servers - Message stores and processors - For advanced enterprise messaging and QoS enforcement (eg: in-order delivery, exactly once delivery) - Mediation templates - The concept of reusable functions to the ESB configuration language - Message broker - Built-in JMS provider/broker powered by Apache Qpid - FTPS support via file transport - Transfer files over SSH connections - Conditional router mediator - Implement advanced and complex routing logic at ease - URL rewrite mediator - Rewrite URLs and URL fragments efficiently - Custom XPath extensions - User defined custom XPath extensions support - New HL7 transport (optional) - Send and receive HL7 messages over MLLP and other transports - New eventing implementation - A powerful event broker with extensive support for WS-Eventing and topic management - Event mediator - Publish events to topics defined in the built-in event broker - LDAP user store - Built-in LDAP service based on Apache Directory Server - Dynamic registry keys and endpoint URL support - Construct registry lookup keys and endpoint URLs dynamically at mediation time *Enhancements in this Release* - Improved Smooks mediator - Enhanced support for service chaining with the receiving sequence support in the send mediator - Improved weighted round robin algorithm for the load balance endpoint - Improvements to caching - Automatic schema imports from the WSDLs added to the registry (for proxy services) - Automatic schema imports from the schema files added to the registry (for validate mediator) - Support for setting properties at the endpoint level - Enhanced Enrich Mediator - Improved support for batch transfers in FIX transport - Validation support for the ESB configuration editor (source view) - Proxy service UI enhancements - Enhanced menu layouts - Local transport for fast in-VM service calls *Key Features of WSO2 ESB* - 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 ultra-fast execution and support for thousands of connections at high concurrency 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. - Load-balancing (with or without sticky sessions)/Fail-over, and clustered Throttling and Caching support - 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 management for configuration development - Integrated monitoring support with statistics, configurable logging and tracing - JMX monitoring support and JMX management capabilities like, Graceful/Forceful shutdown/restart *Bugs Fixed in this Release* This release of WSO2 ESB comes with a number of bug fixes, both in the base framework and the ESB specific components.
