302 Getting Started with IBM Data Studio for DB2 Under the covers, Data Studio starts up the WAS CE instance (if it’s not started already). If this is the first time you’ve deployed a data web service, you may get asked if Data Studio should update the DB2 JDBC driver at the application server. You should confirm this message to be sure that the latest DB2 JDBC driver is used. In the next step Data Studio generates the web service runtime artifacts – like the WSDL file, a JAVA EE web application project (WAR) and deploys all artifacts to the application server. For more information on what those artifacts are and how to locate them, see Appendix E. In addition, because you selected the option to bring up the Web Services Explorer automatically, it will come up automatically for testing. We’ll cover testing in the next section. Note: You can also just build the web service runtime artifacts without automatically deploying them to the application server by selecting Build deployable files only, do not deploy to a web server. Data Studio generates the web application project and *.war file for the web service. You can now take the *.war file and use the application server administration tools to deploy the application manually. 10.8.1. The location of the generated WSDL The content of a SOAP message is usually described in the WSDL (Web Service Description Language) document. WSDL is based on XML as well. Data Studio generates a WSDL for each data web service. In fact, the Web Services Explorer requires the WSDL file to be able to communicate with the web service. To locate the WSDL file for yourSimpleService web service, expand the folder XML -> WSDL in your data development project as shown in Figure 10.19.
Chapter 10 – Developing data web services 303 Figure 10.19 – Locating the WSDL file for the SimpleService You will find a SimpleService.wsdl file that represents the WSDL file for your service. You can also retrieve the WSDL document using a URL after the web service was deployed on an application server. The URL is: http(s)://:///wsdl In the case of theSimpleService, the URL would look like this: http://server:8080/WebServicesBookSimpleService/wsdl Explaining the structure of a WSDL document in detail is beyond the scope of this book. You should know that the WSDL contains all the information a web service client needs to start an operation of your web service. This includes the operation names, XML schemas for input and output messages and, service endpoint definitions. Note: Data Studio also includes a WSDL editor. You open the editor by double-clicking the WSDL document.
