</head>
<body id="axisoverview"><a name="axisoverview"><!-- --></a>
<h1 class="topictitle1">Creating Web services with the Apache Axis2 runtime environments</h1>
<div><p>This runtime environment is for users who prefer to develop for
the open Apache Axis platform. Both Axis1 and Axis2 are supported by the Web
services tools.</p>
<div class="section"><h4 class="sectiontitle">Apache Axis2 Overview</h4><p>Axis2 evolved from the Apache
Axis1.x architecture and is more flexible, configurable, and efficient, while
retaining the positive aspects of Apache Axis1.x architecture.</p>
<div class="p">The Web
service tools provided with this product support the following specifications
when creating Apache Axis2 Web services and clients:<ul>
<li>SOAP 1.1 and 1.2</li>
<li>WSDL 1.1, including both SOAP and HTTP bindings </li>
<li>HTTP transports</li>
</ul>
The levels of Axis2 currently supported by the tools is 1.2 and 1.3.
Axis2 can be deployed to any server that supports Java™ Servlet 2.2 specification or higher,
including IBM<sup>®</sup> WebSphere<sup>®</sup> Application
Server 6.1, and Apache Tomcat server. For more information on Axis2, refer
to <a href="http://ws.apache.org/axis2/" target="_blank">http://ws.apache.org/axis2</a>. </div>
<p>The
support for Apache Axis2 is limited to validation that the application is
invoking the Axis2 emitters correctly. Support for other Axis2 issues should
be directed to <a href="http://ws.apache.org/axis2/" target="_blank">http://ws.apache.org/axis2</a></p>
</div>
<div class="section"><h4 class="sectiontitle">Installing the Apache Axis2 runtime</h4><div class="p">Unlike creating
Web services in the Apache Axis1.x runtime, before creating a Web service
using Apache Axis2 you must download the Axis2 runtime and install it the
workbench using the Web services Axis2 preferences page.<ol>
<li>Download Apache Axis2 v1.2 or v1.3 from the following site: <a href="http://ws.apache.org/axis2/download.cgi" target="_blank">http://ws.apache.org/axis2/download.cgi</a>.</li>
<li>Follow the instructions in the appropriate Apache Axis2 installation guide: <ul>
<li>Apache Axis2 v1.2<a href="http://ws.apache.org/axis2/1_2/installationguide.html" target="_blank">http://ws.apache.org/axis2/1_2/installationguide.html</a></li>
<li>Apache Axis2 v1.3<a href="http://ws.apache.org/axis2/1_3/installationguide.html" target="_blank">http://ws.apache.org/axis2/1_3/installationguide.html</a></li>
</ul>
</li>
<li>Once the Apache Axis2 runtime is installed, you need to associate it with
the workbench. In the workbench, open <span class="menucascade"><span class="uicontrol">Window</span>
> <span class="uicontrol">Preferences</span> > <span class="uicontrol">Web services</span> > <span class="uicontrol">Axis2
Preferences</span></span>. On the <span class="uicontrol">Axis2 Runtime</span> tab,
browse to the location where you installed Apache Axis2. A message will display
if the runtime is installed successfully.</li>
</ol>
</div>
</div>
<div class="section"><h4 class="sectiontitle">Creating projects for Axis2 Web services</h4><div class="p">The Web
service wizards will automatically add the correct facets to a dynamic Web
project. However if you want to manually create a dynamic Web project enabled
for Axis2 Web service development complete the following:<ol>
<li>Create the service Web project by clicking <span class="uicontrol">File > New > Project
> Dynamic Web project</span>. Enter the following information: <ol type="a">
<li>Project Name: Type a project name</li>
<li>If you are deploying to a Tomcat server, ensure that <span class="uicontrol">Add project
to an EAR</span> is not selected. If you do not clear this checkbox you
will be unable to select the Tomcat server. If you are deploying to WebSphere Application
server you will need to add the project to an EAR.</li>
<li>Target runtime: Select the version of the server to which you will deploy
your Web service. If it is not listed, click <span class="uicontrol">New</span> and
browse to the location where it is installed.</li>
<li>Configurations: Select the default configuration for your server type.</li>
<li>Click <span class="uicontrol">Finish</span>.</li>
</ol>
</li>
<li>Add the Axis2 facet. Right-click your project and click <span class="menucascade">
<span class="uicontrol">Properties</span> > <span class="uicontrol">Project Facets</span> > <span class="uicontrol">Modify
project</span> > <span class="uicontrol">Axis2 Web Services</span></span>,
and click <span class="uicontrol">Finish</span>.</li>
<li>If you have chosen to deploy to a server in which the Axis2 JAR files
will reside on the server (such as WebSphere Application Server), you must
change the classloading for the EAR from PARENT_FIRST to PARENT_LAST. Expand
the EAR associated with your Axis2 project, and launch its deployment descriptor.
On the <span class="uicontrol">Deployment</span> tab, expand the <span class="uicontrol">Application</span> section.
Change the <span class="uicontrol">Classloader mode</span> field to PARENT_LAST and
save your changes.</li>

The Web Service wizard assists you in creating a new Web service, configuring it for deployment, and deploying the Web service to a server. Once your Web service is deployed, the wizard assists you in generating the client proxy and sample application to test the Web service. When you have completed testing, you can publish your Web service to a UDDI Business Registry using the Export wizard.</li>
<li class="ulchildlink"><strong><a href="../topics/taxis2td.html">Creating a Java bean skeleton from a WSDL document using the Apache Axis2 runtime environment</a></strong><br />
The Web service wizard assists you in creating a skeleton bean from an existing WSDL document. The skeleton bean contains a set of methods that correspond to the operations described in the WSDL document. When the bean is created, each method has a trivial implementation that you replace by editing the bean.</li>
