| <h1>Welcome to Apache Axis2/Java</h1> | |
| <h2>13th November 2006 - Apache Axis2/Java Version 1.1 Released!</h2> | |

| <p>Apache Axis2 is the core engine for Web services. It is a complete | |
| re-design and re-write of the widely used <a | |
| href="http://ws.apache.org/axis/">Apache Axis</a> SOAP stack to build on the | |
| lessons learnt from Apache Axis.</p> | |
| <h3><em>Apache Axis Project in a Nutshell:</em></h3> | |
| <p>Apache Axis is an implementation of the SOAP ("Simple Object Access | |
| Protocol") <a href="http://www.w3.org/TR/SOAP">submission</a> to W3C.</p> | |
| <p>Extract from the draft W3C specification:</p> | |
| <blockquote> | |
| "SOAP is a lightweight protocol for exchanging structured information in a | |
| decentralized, distributed environment. It is an XML based protocol that | |
| consists of three parts: an envelope that defines a framework for | |
| describing what is in a message and how to process it, a set of encoding | |
| rules for expressing instances of application-defined datatypes, and a | |
| convention for representing remote procedure calls and | |
| responses."</blockquote> | |
| <p>This project is a follow-on to the <a | |
| href="http://ws.apache.org/soap">Apache SOAP project</a>.</p> | |
| <p>Please see the <a href="http://ws.apache.org/axis/ref.html">Axis Reference | |
| Library</a> for a list of technical resources that should prove useful on | |
| this project.</p> | |
| <h3><em>Why Apache Axis2:</em></h3> | |
| <p>A new architecture for Axis was introduced during the August 2004 Summit | |
| in Colombo, Sri Lanka. This new architecture Axis2 is based on is more | |
| flexible, efficient and configurable in comparison to <a | |
| href="http://ws.apache.org/axis/java/architecture-guide.html">Axis1.x | |
| architecture</a>. Some well established concepts from Axis 1.x, like handlers | |
| etc., have been preserved in this new architecture.</p> | |
| <p>Apache Axis2 not only supports SOAP 1.1 and SOAP 1.2, but it also has | |
| integrated support for the widely popular <a | |
| href="http://www.xfront.com/REST-Web-Services.html">REST style of Web | |
| services</a>: the same business logic implementation can offer both a WS-* | |
| style interface as well as a REST style interface simultaneously.</p> | |
| <p>Apache Axis2 is more efficient, more modular and more XML-oriented than | |
| the older version. It is carefully designed to support the easy addition of | |
| plug-in "modules" that extend its functionality for features such as security | |
| and reliability. <a | |
| href="http://ws.apache.org/axis2/modules/index.html">Modules</a> currently | |
| available or under development include:</p> | |
| <ul> | |
| <li><a | |
| href="http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=wsrm" | |
| target="_blank">WS-ReliableMessaging</a> - Supported by <a | |
| href="http://ws.apache.org/sandesha/sandesha2/">Apache Sandesha2</a></li> | |
| <li><a | |
| href="http://www-128.ibm.com/developerworks/library/specification/ws-tx/#coor" | |
| target="_blank">WS-Coordination</a> and <a | |
| href="http://www-128.ibm.com/developerworks/library/specification/ws-tx/#atom" | |
| target="_blank">WS-AtomicTransaction</a> - Supported by <a | |
| href="http://ws.apache.org/kandula/">Apache Kandula2</a></li> | |
| <li><a | |
| href="http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=wss" | |
| target="_blank">WS-Security</a> - Supported by <a | |
| href="http://ws.apache.org/axis2/modules/index.html">Apache | |
| Rampart</a></li> | |
| <li><a href="http://www.w3.org/Submission/ws-addressing/" | |
| target="_blank">WS-Addressing</a> -Module included as part of Axis2 | |
| core</li> | |
| </ul> | |
| <p>Apache Axis2 is built on <a | |
| href="http://ws.apache.org/commons/axiom/index.html">Apache AXIOM</a>, a new | |
| high performant, pull-based XML object model that was released two days | |
| ago.</p> | |
| <p>Axis2 comes with many new features, enhancements and industry | |
| specification implementations. The key features offered are as follows:</p> | |
| <ul> | |
| <li><p style="margin-bottom: 0in"><strong>Speed</strong> - Axis2 uses its | |
| own object model and StAX (Streaming API for XML) parsing to achieve | |
| significantly greater speed than earlier versions of Apache Axis.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>Low memory foot print</strong>- | |
| Axis2 was designed ground-up keeping low memory foot print in mind.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>AXIOM</strong> - Axis2 comes with | |
| its own light-weight object model, AXIOM, for message processing which is | |
| extensible, highly performant and is developer convenient.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong><a name="Hot_Deployment"></a>Hot | |
| Deployment</strong> - Axis2 is equipped with the capability of | |
| deploying Web service & handlers while the system is up and running. | |
| In other words, new services can be added to the system without having to | |
| shut down the server. Simply drop the required Web service archive into | |
| the services directory in the repository and the deployment model will | |
| automatically deploy the service and make it available for use.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>Asynchronous Web | |
| services</strong> - Axis2 now supports asynchronous Web services & | |
| asynchronous Web services invocation using non-blocking clients and | |
| transports .</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>MEP Support</strong> - Axis2 now | |
| comes handy with the flexibility to support Message Exchange Patterns | |
| (MEPs) with in-built support for basic MEPs defined in WSDL 2.0.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>Flexibility</strong> - The Axis2 | |
| architecture gives the developer complete freedom to insert extensions | |
| into the engine for custom header processing, system management, and | |
| <em>anything else you can imagine</em>.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>Stability</strong> - Axis2 | |
| defines a set of published interfaces which change relatively slowly | |
| compared to the rest of Axis.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>Component-oriented | |
| Deployment</strong> - You can easily define reusable networks of Handlers | |
| to implement common patterns of processing for your applications, or to | |
| distribute to partners.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>Transport Framework</strong> - We | |
| have a clean and simple abstraction for integrating and using Transports | |
| (i.e., senders and listeners for SOAP over various protocols such as | |
| SMTP, FTP, message-oriented middleware, etc), and the core of the engine | |
| is completely transport-independent.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>WSDL support</strong> - Axis2 | |
| supports the Web Service Description Language, version <a | |
| href="http://www.w3.org/TR/wsdl">1.1</a> and <a | |
| href="http://www.w3.org/TR/wsdl20/">2.0</a>, which allows you to easily | |
| build stubs to access remote services, and also to automatically export | |
| machine-readable descriptions of your deployed services from Axis2.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>Add-ons</strong> - Several Web | |
| services specifications have been incorporated including <a | |
| href="http://ws.apache.org/wss4j/" target="_blank">WSS4J</a> for security | |
| (Apache Rampart), <a href="http://ws.apache.org/sandesha/" | |
| target="_blank">Sandesha</a> for reliable messaging, <a | |
| href="http://ws.apache.org/kandula/" target="_blank">Kandula</a> which is | |
| an encapsulation of WS-Coordination, WS-AtomicTransaction and | |
| WS-BusinessActivity.</p> | |
| </li> | |
| <li><p style="margin-bottom: 0in"><strong>Composition and | |
| Extensibility</strong> - Modules and phases improve support for | |
| composability and extensibility. Modules supports composability and is | |
| able to add support for new WS-* specifications in a simple and clean | |
| manner. They are however not <a href="#Hot_Deployment">hot deployable</a> | |
| as they change the overall behavior of the system.</p> | |
| </li> | |
| </ul> | |
| <p>We hope you enjoy using Axis2. Please note that this is an open-source | |
| effort. If you feel the code could use new features or fixes, or the | |
| documentation can be improved, please get involved and lend us a hand! The | |
| Axis developer community welcomes your participation.</p> | |
