<h2>Welcome to Apache Axis2/C</h2>
<p>Apache Axis2/C is a Web services engine implemented in the C programming language. It is based on the extensible and flexible <a href="http://ws.apache.org/axis2/1_2/Axis2ArchitectureGuide.html" class="externalLink" title="External Link">Axis2 architecture</a>. Apache Axis2/C can be used to provide and consume WebServices. It has been implemented with portability and ability to embed in mind, hence could be used as a Web services enabler in other software.</p>
<p>Apache Axis2/C supports <a href="http://www.w3.org/TR/2000/NOTE-SOAP-20000508/" class="externalLink" title="External Link">SOAP 1.1</a> and <a href="http://www.w3.org/TR/soap12-part1/" class="externalLink" title="External Link">SOAP 1.2</a>, as well as <a href="http://www.xfront.com/REST-Web-Services.html" class="externalLink" title="External Link">REST</a> style of Webservices. A single service could be exposed both as a SOAP style as well as a REST style service simultaneously. It also has built in <a href="http://www.w3.org/TR/soap12-mtom/" class="externalLink" title="External Link">MTOM</a> support, that can be used to exchange binary data.</p>
<p>Apache Axis2/C is efficient, modular and is designed with extensibility. The extensible design allows it to support the full WS-* stack with the concept of modules. Apache Axis2/C is the Web services engine that supports the most number of WS-* specification implementations in C, with guaranteed interoperability. This enables using C in Service Oriented Architecture (SOA) implementations, and would be very useful when integrating legacy systems into SOA.
<br></br>
The following WS-* specifications are supported, either as built in modules
or as separate Apache projects: </p>
<ul>
<li><a href="http://www.w3.org/Submission/ws-addressing/" class="externalLink" title="External Link">WS-Addressing</a> - Built in to Axis2/C </li>
<li><a href="http://www.w3.org/Submission/WS-Policy/" class="externalLink" title="External Link">WS-Policy</a> - Built in to Axis2/C </li>
<li><a href="http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=wss" class="externalLink" title="External Link">WS-Security</a> - Implemented by <a href="http://ws.apache.org/axis2/modules/rampart/1_2/security-module.html" class="externalLink" title="External Link">Apache Rampart/C</a> project </li>
<li> <a href="http://specs.xmlsoap.org/ws/2005/07/securitypolicy/ws-securitypolicy.pdf" class="externalLink" title="External Link">WS-SecurityPolicy</a> - Built in to Axis2/C </li>
<li> <a href="http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=wsrm" class="externalLink" title="External Link">WS-ReliableMessaging</a> - Implemented by <a href="http://ws.apache.org/sandesha/sandesha2/c" class="externalLink" title="External Link">Apache Sandesha2/C</a>project
</li>
<li><a href="http://www.w3.org/Submission/WS-Eventing/" class="externalLink" title="External Link">WS-Eventing</a> - Implemented by <a href="http://ws.apache.org/savan/c/" class="externalLink" title="External Link">Apache Savan/C</a>project</li>
