# Generating a Java client proxy and a sample application from a WSDL document using the Axis2 runtime environment

The Web Service Client wizard assists you in generating a Java™ bean proxy and a sample application. The sample Web application demonstrates how to code a proxy file.

Prerequisites:

1. You must have installed the Apache Axis2 runtime environment as described in: Creating Web services with the Apache Axis2 runtime environments
2. 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: Creating an Apache Tomcat server and Web project
3. Discover and import a WSDL document into the Web project. You can only use a WSDL file that contains a service element.

To generate a Java client proxy and a sample application from a discovered WSDL document:

1. Switch to the Java EE perspective (Window > Open Perspective > Java EE).
2. In the Navigator view, select the Web project in which you want to generate a sample application.
3. Click File > New > Other. Select Web Services in order to display the various Web service wizards. Select the Web Service Client wizard. Click Next.
4. Web Services page:
   1. Enter the URI to the WSDL, WSIL, or HTML file that will be used to generate the client.
   2. Select the type of proxy to be generated
   3. Select the stages of Web services development that you want to complete using the slider:
      - 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 and Java files, as well as copying the Axis JARs..
      - 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.
      - Deploy: this will create the deployment code for the service.
      - Install: this will install and configure the Web module and EARs on the target server.
      - Start: this will start the server once the service has been installed on it. The server-config.wsdd file will be generated.
      - Test: this will provide various options for testing the service, such as using the Web Service Explorer or sample JSPs.
   4. Select your server: the default server is displayed. If you want to deploy your client to a different server click the link to specify a different server.
   5. Select your runtime: ensure the Apache Axis2 runtime is selected.
   6. Select the client project: the project containing the project selected in your workspace is displayed. To select a different project and EAR click on the project link. 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.
   7. 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 Using the TCP/IP Monitor to test Web services
5. Axis2 Client Web service configuration page: Use this page to select the following options:
   1. Service Name: accept the default.
   2. Port Name: accept the default.
   3. Databinding Name: only the Axis2 Databinding Framework (ADB) is supported at this time.
   4. Custom package name: You can change the package name in this field.
   5. Client mode: You can choose if the client is synchronous, asynchronous, or both.
   6. Generate test case to test the service: If you select this, the Axis2 emitter will generate JUnit testcases matching the WSDL provided to the client. These JUnit testcases will be generated to a newly added source directory to the client project called test.
   7. Generate all types for all elements referred by schemas
   8. Namespace to package mapping: Use this table to review or edit the mappings between packages and namespaces.
6. Web Service Client Test page: Use this page to select the following options:
   1. Select your test facility. You can test the generated proxy in the Web Service Explorer, or the Universal Test Client.
   2. Select Run test on server to start the server for you automatically.
7. Click Finish. If you have selected to test the proxy, the test client will open in a browser window.

The generated Java bean proxy provides a remote procedure call interface to the Web service. The sample Web application demonstrates how to code the proxy file.

Once you have generated your Java client proxy, you may test the methods of the Web service through the proxy using Web Services sample JSPs or the Universal test client.

- 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: port/ WebProjectClient/sampleBeanName/ WebServiceName/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 Invoke. The result of the method will display in the results pane.
- 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 Go. The result will display in the Status pane.
