The WSO2 ESB team is pleased to announce the release of version 3.0.0 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. 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 mediation engine.
WSO2 ESB 3.0.0 is developed on top of the revolutionary WSO2 Carbon platform (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/esb and give it a try.
How to Run
- Extract the downloaded zip
- Go to the bin directory in the extracted folder
- Run the wso2server.sh or wso2server.bat as appropriate
- Point your browser to the URL https://localhost:9443/carbon
- Use "admin", "admin" as the username and password to login as an admin and create a user account
- Assign the required permissions to the user through a role
- If you need to start the OSGi console with the server use the property -DosgiConsole when starting the server. The INSTALL.txt file found on the installation directory will give you a comprehensive set of options and properties that can be passed into the startup script
- Sample configurations can be started by the wso2esb-samples script passing the sample number with the -sn option (Please have a look at the samples guide for more information, on running samples)

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 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 ..)
- 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

- Endpoint UI does not support selecting already existing endpoints as child endpoints when creating load balance/failover endpoints
- 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
