Web services are applications that use open, XML-based standards and transport protocols to exchange data with clients. We shall discuss the new clientjar option in the wsimport tool or the wsimport ant task which is used to generate JAX-WS portable artifacts from a service wsdl.
Subsequently, we use the web service artifacts to invoke the web service from a web service client. Deepak Vohra is consultant and principle a member of the NuBean software company.

In the Installation Type window, select Typical Installation. Ports and must be available. For example, if the Oracle database XE is installed and running, the database needs to be stopped. Click on Next: The directory does not need to be created prior to specifying the Installation Directory: Select the Enable Update Tool to enable the update tool.
The installation of GlassFish Server 3. If the domain creation fails with the error: The start-domain command gets invoked: The Admin Port is The Oracle GlassFish Server is now installed and configured. Click on Exit: The server can be accessed at http: As we already installed the standalone version of the Oracle GlassFish Server, deselect the checkbox for the GlassFish Sever and also deselect the checkbox for the Apache Tomcat server. In the License Agreement window, select the checkbox to accept the agreement and click on Next.
The Summary of the installation is then displayed. Click on Install: When the installation completes, click on Finish. We need to install the following JDK and software as discussed in the previous chapter: This chapter has the following sections: Specifically, wsimport generates the following artifacts: The WSDL location is saved in the generated artifacts and the JAX-WS runtime fetches the metadata, which is useful if the endpoint policy or the service definition has changed.
In the absence of the runtime fetch of the metadata, the clients would need to be regenerated if the endpoint policy or the service definition have changed. What is new in Java 7 wsimport?
By including the generated JAR file in the classpath of the web service client, there is no need to fetch the WSDLs from the endpoint each time a service instance is created, thus saving on network overhead. WebService annotation—the web service endpoint. A web service may optionally consist of a Service Endpoint Interface SEI that is implemented by the service endpoint implementation class. A web service implementation class must not be abstract or final. Business methods of the implementation class that are to be exposed as operations to a web service client must be public, must not be static or final, and must be annotated with the WebMethod annotation.
Downloading the example code You can download the example code fles for all Packt books you have purchased from your account at http: Uncheck the checkbox Create Main Class, and click on Finish: The Java platform for the project should be set to Java 7. To do this, right-click on the project node and select Properties. The JDK 1. Select File New File.
The implementation class contains a method hello that takes a String parameter for name and returns a Hello message containing the name. The implementation class is listed as follows: The SEI declares public methods that clients may invoke on the service. As we specified, an explicit SEI with an endpointInterface element in the WebService annotation in the implementation class, we must include a SEI with public methods made available on the service.
The service endpoint interface HelloWS contains the hello method annotated with the WebMethod annotation: WebMethod; import javax.
The HelloWSService. Defines abstract operations. Also describes the data formats for the messages defined by the portType element.
To learn more about WSDL refer to http: The tns namespace prefix defines the http: The schema has elements hello and helloResponse. The hello element is of type tns: The helloReponse element is of type tns: The schema for the element is listed as follows: Creating the deployment descriptors The web.
The following listener and servlet classes are configured in web. Listener class com. The web. HelloWebService com. The sun-jaxws.
The deployment descriptor has root element endpoints and one or more endpoint elements, each of which represents a port in the WSDL. The sample sun-jaxws. Attribute Value Description name fromwsdl The endpoint name. HelloWSImpl Specifies the implementation class. Required element.
Should be the same as the url-pattern in web. Copy the sun-jaxws. Creating a client class Create a client Java class hellowsclient. Obtain a proxy to the service from the service using the getHelloWSPort method: The Java client class is listed as follows: HelloWSService ; hellows. A build file fragment may be used for specifying deployment targets.
Create a deploy-targets. Specify properties for the GlassFish Server directory, the build directory, the. Create a "deploy" target to deploy the web service WAR file to the autodeploy directory of the GlassFish Server domain.
Deploying to the GlassFish Server is essentially copying to the autodeploy directory. The deploytargets.
Create a build. The build. In the build.
Property java. In build. Build the web service WSDL to generate web service artifacts using the wsimport task. Compile the web service implementation class. Create a WAR file from the web service classes and deployment descriptors. Compile the client class HelloWSClient. Run the web service client. Specify the targets in build. Target Description setup Build the required directories.
WsImport class, which defines the wsimport task: The new —clientjar option is not needed for the web service to get deployed on the GlassFish Server. In the build-server-wsdl target, run the wsimport task to generate the web service artifacts from the web service WSDL.
Also, compile the web service implementation class: In the server target invoke clean, build-server-wsdl, create-war, and the deploy target from the deploy-targets. Building the client Next, we demonstrate the new —clientjar option in wsimport to generate a JAR file for the web service portable artifacts and WSDLs to be made available to the JAXWS runtime when the web service is invoked from a client.
In the generate-client target, run the wsimport task and specify the JAR file to package the generated artifacts and WSDLs using the clientjar attribute. In the wsdl URL, clientjar is the WAR file name for the deployed web service and hellows is the servlet pattern to invoke the web service servlet as specified in web. As the JAR file is to be made available to the client at runtime, specify the package name the same as the package for the client class: In the client target compile the client class using the javac task with the JAR file generated using the —clientjar option in the classpath: Running the client Next, we run the client class in the run target using the java task with the JAR file generated using the —clientjar option in the classpath: We shall run the build.
Deleting directory C: Created dir: Generating code Compiling code Compiling 1 source file to C: Building war: Copying 1 file to C: Right-click on the client target and select Run Target: Archiving the generated artifacts in to C: Right-click on the run target and select Run Target: The client class runs and the web service gets invoked to generate a Hello message as shown in the following screenshot: Hello John Smith.
