| <h1 class="topictitle1">Creating a Java bean skeleton from a WSDL document using the Apache |
| Axis run-time environment</h1> |
| |
| |
| |
| |
| <div><p>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.</p> |
| |
| <div class="p"><p>Prerequisites:</p> |
| <ol> |
| <li>If you are using the Apache Jakarta Tomcat servlet |
| container as your server, you must install it, configure an instance of it, |
| and create a Web project targeted to it as described in <a href="ttomcatserv.html">Creating an Apache Tomcat server and Web project</a></li> |
| |
| <li>Create or import a WSDL file into the Web Content folder of the Web project. |
| You can only use a WSDL file that contains a service element.</li> |
| |
| </ol> |
| </div> |
| |
| <div class="section">To create a Web service from a WSDL file using the Apache Axis run-time |
| environment:</div> |
| |
| <ol> |
| <li><span>Switch to the J2EE perspective (<span class="uicontrol">Window > Open Perspective |
| > J2EE</span>).</span></li> |
| |
| <li><span>In the Project Explorer view, select the WSDL file that you created |
| or imported into the Web Content folder of your Web project.</span></li> |
| |
| <li><span>Click <span class="uicontrol">File > New > Other</span>. Select <span class="uicontrol">Web |
| Services</span> in order to display the various Web service wizards. |
| Select the <span class="uicontrol">Web Service</span> wizard. Click <span class="uicontrol">Next</span>.</span> |
| </li> |
| |
| <li><span>Web Services page: select <span class="uicontrol">Top down Java bean Web service</span> as |
| your Web service type, and select the artifact from which the service will |
| be created.</span> |
| <ol type="a"> |
| <li class="substepexpand"><span>Select the stages of Web services development that you want |
| to complete using the slider:</span> <ul> |
| <li>Develop: this will develop the WSDL definition and implementation of the |
| Web service. This includes such tasks as creating the modules which will contain |
| the generated code, WSDL files, deployment descriptors, and Java files when |
| appropriate.</li> |
| |
| <li>Assemble: this ensures the project that will host the Web service or client |
| gets associated to an EAR when required by the target application server.</li> |
| |
| <li>Deploy: this will create the deployment code for the service.</li> |
| |
| <li>Install: this will install and configure the Web module and EARs on the |
| target server.</li> |
| |
| <li>Start: this will start the server once the service has been installed |
| on it. The server-config.wsdd file will be generated.</li> |
| |
| <li>Test: this will provide various options for testing the service, such |
| as using the Web Service Explorer or sample JSPs.</li> |
| |
| </ul> |
| </li> |
| |
| <li class="substepexpand"><span>Select your server: the default server is displayed. If you |
| want to deploy your service to a different server click the link to specify |
| a different server.</span></li> |
| |
| <li class="substepexpand"><span>Select your runtime: the default runtime is displayed. If you |
| want to deploy your service to a different runtime click the link to specify |
| a different runtime.</span></li> |
| |
| <li class="substepexpand"><span>Select the service project: the project containing the project |
| selected in your workspace is displayed. To select a different project and |
| EAR click on the project link.</span> Ensure that the project selected |
| as the Client Web Project is different from the Service Web Project, or the |
| service will be overwritten by the client's generated artifacts.</li> |
| |
| <li class="substepexpand"><span>If you want to create a client, select the type of proxy to |
| be generated and repeat the above steps for the client.</span></li> |
| |
| <li class="substepexpand"><span>Publish the Web service: this will launch the Web Services Explorer |
| to publish your Web service to a UDDI registry.</span></li> |
| |
| <li class="substepexpand"><span>Monitor the Web service: this will send the Web service traffic |
| through the TCP/IP Monitor, which allows you to watch the SOAP traffic generated |
| by the Web service and to test this traffic for WS-I compliance. Alternately |
| you can manually set up a TCP/IP monitor as described in <a href="../../org.eclipse.wst.wsi.ui.doc.user/tasks/tmonitor.html">Using the TCP/IP Monitor to test Web services</a></span></li> |
| |
| </ol> |
| |
| </li> |
| |
| <li><span>Web Services Skeleton Java™ Bean Configuration page: Select the |
| folder where the generated Java will be stored. If you want to review |
| or edit the mappings between packages and namespaces, select the <span class="uicontrol">Define |
| custom mapping for namespace to package</span> check box. Click <span class="uicontrol">Next</span>.</span> |
| </li> |
| |
| <li><span>Web Service Namespace to Package Mappings page: if you selected |
| <span class="uicontrol">Define custom mapping for package to namespace</span> on |
| the previous panel, you can enter your custom mapping pairs on this panel |
| by clicking <span class="uicontrol">Add</span>. Alternately, you can click <strong>Import</strong> to |
| import custom mapping pairs from a <tt class="sysout">.properties</tt> file. |
| The content of the properties file must be of the format <samp class="codeph"><var class="varname">namespace=package</var></samp>. |
| Click <span class="uicontrol">Next</span>.</span></li> |
| |
| <li><span>Web Service Test page: If you selected to test the Web service, |
| select the test facility for the generated Web service. This will open the |
| Web service in the Web Services Explorer. Select the operation you want to |
| test, enter the required information, and click <span class="uicontrol">Go</span>. |
| The result will display in the Status pane. Click <span class="uicontrol">Next</span>.</span> |
| </li> |
| |
| <li><span>Web Service Proxy page: If you have selected to generate a proxy, |
| this page shows the options for the proxy. It lists the folder where the proxy |
| will be generated, and you can optionally create custom mappings between namespaces |
| and packages. Click <span class="uicontrol">Next</span>.</span></li> |
| |
| <li><span>Web Service Client Test page: Use this page to select the following |
| options: </span> |
| <ol type="a"> |
| <li><span>Select your test facility. You can test the generated proxy |
| in the Web Service Explorer, or you can generate a sample Web service JSP.</span> |
| </li> |
| |
| <li><span>If you selected to test the proxy through a JSP, you can select |
| the folder where the JSP will be located, and you can select the methods that |
| will be included in the JSP.</span></li> |
| |
| <li><span>Select <span class="uicontrol">Run test on server</span> to start the |
| server for you automatically.</span></li> |
| |
| </ol> |
| |
| </li> |
| |
| <li><span>Web Service Publication page: If you have selected to publish your |
| Web service to a UDDI registry, use this page to launch the Web Services Explorer |
| and select the UDDI registry to which the Web service will be published. Click |
| <span class="uicontrol">Finish</span>.</span></li> |
| |
| </ol> |
| |
| <div class="section"><div class="p">After the Web service has been created, |
| the following may occur depending on the options you selected: <ul> |
| <li>If you have selected to test the generated proxy using Web service JSPs, |
| the proxy is launched in a Web browser at the following URL: http://localhost: <var class="varname">port</var>/ <var class="varname">WebProject</var>Client/sample<em>BeanName</em>/ <var class="varname">WebServiceName</var>/TestClient.jsp You can use |
| this sample application to test the Web service by selecting a method, entering |
| a value for the method, and clicking <span class="uicontrol">Invoke</span>. The result |
| of the method will display in the results pane.</li> |
| |
| <li>If you have selected to test the Web service using the Web Services Explorer, |
| the Explorer will open. Select the operation you want to test, enter the required |
| information, and click <strong>Go</strong>. The result will display in the Status pane.</li> |
| |
| <li>If you have selected to publish the Web service, the Web Services Explorer |
