Creating a Simple Web Service and Client with JAX WSCreating a Simple Web Service and Client with JAX WSThis section shows how to build and deploy a simple web service and. The source code for the service is in tut installjavaeetutorial. Figure 1. 6 1 illustrates how JAX WS technology manages communication between a web service and client. Figure 1. 6 1 Communication between a JAX WS Web Service and a Client. The starting point for developing a JAX WS web service is a Java. Web. Service annotation. The Web. Service annotation defines the class as a. A service endpoint interface or service endpoint implementation SEI is a Java interface or class, respectively, that. An. interface is not required when building a JAX WS endpoint. The web service implementation class. SEI. You may specify an explicit interface by adding the endpoint. Interface element to. Web. Service annotation in the implementation class. You must then provide an interface. You use the endpoint implementation class and the wsgen tool to generate the web. JAX WS runtime. Together, the wsgen tool and the Application Server provide the Application Servers implementation. JAX WS. These are the basic steps for creating the web service and client Code the implementation class. Compile the implementation class. Use wsgen to generate the artifacts required to deploy the service. Package the files into a WAR file. Deploy the WAR file. The web service artifacts which are used to communicate with clients are generated by the Application Server during deployment. Code the client class. Use wsimport to generate and compile the web service artifacts needed to connect to the service. Compile the client class. Run the client. The sections that follow cover these steps in greater detail. Requirements of a JAX WS Endpoint. JAX WS endpoints must follow these requirements The implementing class must be annotated with either the javax. Web. Service or javax. Web. Service. Provider annotation. The implementing class may explicitly reference an SEI through the endpoint. Interface element of the Web. Service annotation, but is not required to do so. If no endpoint. Interface is specified in Web. Service, an SEI is implicitly defined for the implementing class. The business methods of the implementing class must be public, and must not be declared static or final. Business methods that are exposed to web service clients must be annotated with javax. Web. Method. Business methods that are exposed to web service clients must have JAXB compatible parameters and return types. See Default Data Type Bindings. The implementing class must not be declared final and must not be abstract. The implementing class must have a default public constructor. The implementing class must not define the finalize method. The implementing class may use the javax. Post. Construct or javax. Pre. Destroy annotations on its methods for life cycle event callbacks. The Post. Construct method is called by the container before the implementing class begins responding to web service clients. The Pre. Destroy method is called by the container before the endpoint is removed from operation. Coding the Service Endpoint Implementation Class. In this example, the implementation class, Hello, is annotated as a web service. Web. Service annotation. Hello declares a single method named say. Hello, annotated. Web. Method annotation. Web. Method exposes the annotated method to web service. Hello returns a greeting to the client, using the name passed. Hello to compose the greeting. The implementation class also must define a. Web. Service. public class Hello. String message new StringHello,. Hello. public String say. HelloString name. Building, Packaging, and Deploying the Service. You can build, package, and deploy the helloservice application using either Net. Beans IDE. or ant. Building, Packaging, and Deploying the Service Using Net. Beans IDEFollow these instructions to build, package, and deploy the helloservice example to. Application Server instance using Net. Beans IDE. In Net. Beans IDE, select FileOpen Project. In the Open Project dialog, navigate to tut installjavaeetutorial. Select the helloservice folder. Select the Open as Main Project check box. Click Open Project. In the Projects tab, right click the helloservice project and select Undeploy and Deploy. This builds and packages to application into helloservice. WAR file to your Application Server instance. Building, Packaging, and Deploying the Service Using Ant. To build and package helloservice using Ant, in a terminal window, go to. This command calls the default target, which builds and packages the application into. WAR file, helloservice. To deploy the helloservice example, follow these steps In a terminal window, go to tut installjavaeetutorial. Make sure the Application Server is started. Run ant deploy. You can view the WSDL file of the deployed service by requesting. URL http localhost 8. WSDL in a web browser. Now you are ready to create a. Undeploying the Service. At this point in the tutorial, do not undeploy the service. When. you are finished with this example, you can undeploy the service by typing. The all Task. As a convenience, the all task will build, package, and deploy the application. To do this, enter the following command ant all. Testing the Service without a Client. The Application Server Admin Console allows you to test the methods of. To test the say. Hello method of Hello. Service, do the. following Open the Admin Console by typing the following URL in a web browser http localhost 4. Enter the admin user name and password to log in to the Admin Console. Click Web Services in the left pane of the Admin Console. Click Hello. Click Test. Under Methods, enter a name as the parameter to the say. Hello method. Click the say. Hello button. This will take you to the say. Hello Method invocation page. Under Method returned, youll see the response from the endpoint. A Simple JAX WS Client. Hello. Client is a stand alone Java program that accesses the say. Hello method of Hello. Service. It. makes this call through a port, a local object that acts as. The port is created at development time. JAX WS portable artifacts based on a. WSDL file. Coding the Client. When invoking the remote methods on the port, the client performs these steps Uses the javax. Web. Service. Ref annotation to declare a reference to a web service. Web. Service. Ref uses the wsdl. Cara Instal Computer Dari Awal. Location element to specify the URI of the deployed services WSDL file. Web.
