| <h1>Welcome to Apache Axis2/Java</h1> |
| |
| <h2>09th January 2006 - Apache Axis2/Java Version 1.1.1 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, built 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. The new architecture on which 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 the 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 their functionality for features such as |
| security and reliability. The <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/rampart/1_1/security-module.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.</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 services and 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 and |
| 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 support composability and can |
| also support 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> |
