| <h2>Introduction</h2> |
| <br></br> |
| <p> |
| This document is one of a series of tutorials to |
| demonstrate the use of the Web Services tools in the Web |
| Tools Platform Project using the <b>WTP 1.0 M9 drivers</b>. |
| </p> |
| <p> |
| This tutorial shows how to create a simple top-down Web |
| service from a WSDL file. The WSDL file in this scenario |
| calculates the area of an rectangle. |
| |
| </p> |
| <br></br> |
| |
| |
| <h2>Set Up</h2> |
| <br></br> |
| <p> Before creating the Web service, there are two |
| prerequisites: </p> |
| <ol> |
| <li> |
| <a href="InstallTomcat.html">Install Apache Tomcat</a> |
| </li> |
| <li> |
| <a href="CreateWebProject.html"> |
| Create a dynamic Web project |
| </a> |
| called |
| <tt>AreaProj</tt> |
| . |
| </li> |
| |
| </ol> |
| |
| |
| |
| <h2>Create a top down Java bean Web service</h2> |
| |
| <ol> |
| <li> |
| Import the file |
| <a href="resources/AreaService.wsdl">AreaService.wsdl</a> |
| into AreaProj/WebContent. |
| </li> |
| |
| <li>Select the <b>AreaService.wsdl</b> file.</li> |
| |
| <li> |
| Open File -> New -> Other... -> Web Services -> Web |
| Service. |
| </li> |
| <li>Click <b>Next</b></li> |
| <li> |
| In the Web service type combo, select |
| <b>Top down Java bean Web Service</b> |
| . |
| </li> |
| |
| <li> |
| Select |
| <b>Overwrite files without warning</b> |
| . Result: |
| </li> |
| |
| <br/> |
| <img border="0" |
| SRC="resources/td1.jpg" /> |
| <br/> |
| |
| <li> |
| Click |
| <b>Next</b> |
| . Result: |
| </li> |
| |
| <br></br> |
| <img border="0" |
| src="resources/td2.jpg" /> |
| <br></br> |
| |
| <li> |
| Click |
| <b>Next</b> |
| to get to the |
| <b>Service Deployment Configuration Page</b> |
| . Result: |
| </li> |
| |
| <br></br> |
| <img border="0" |
| src="resources/td3.jpg" /> |
| <br></br> |
| |
| <li> |
| If you want to choose a server different |
| from the one defaulted by the wizard, click the |
| <b>Edit</b> |
| button to: |
| <a href="SelectServer.html"> |
| select a server |
| </a> |
| </li> |
| <li> |
| Click |
| <b>Finish</b>. |
| </li> |
| <li> |
| It will take about one minute for the wizard to assemble |
| the Web service projects, start Apache Tomcat and deploy |
| the projects to Tomcat. Once finished, the Java |
| implementation file |
| <b>AreaServiceSOAPImpl.java</b> |
| will appear in the browser view. Fill in the expression |
| <b>parameters.getHeight()*parameters.getWidth()</b> |
| as the return value for the <tt>calculateRectArea</tt> method and save the file. |
| </li> |
| |
| <br /> |
| <img border="0" |
| SRC="resources/td4.jpg" /> |
| </ol> |
| <p> |
| Follow the instructions at |
| <a href="WebServiceClient.html"> |
| Creating Web Service Client |
| </a> |
| to create a Web service client that you can then use to test this Web service. |
