Creating Service Client with WSDL Document
This section provides a tutorial example on how to create a ServiceClient object with a given WSDL document, a service name and a port name defined in the WSDL document.
Before looking at other Axis2 class, let's take a closer look at how to create a service client object from an existing WSDL document using this constructor method:
org.apache.axis2.client.ServiceClient client = new ServiceClient(null, wsdlURL, serviceQName, portName) // "null" indicates a default ConfigurationContext object to be used // "wsdlURL" specifies a WSDL document using a new URL(wsdlUrlString) // "serviceQName" specifies a service within the WSDL document // using a new QName(tns,serviceName) // "tns" specifies the target namespace of the Web service // "portName" specifies a port within the service using the port name
Now let's write a test program, Axis2ServiceClientHello.java, to create a service client with my hello WSDL document, which is located at http://www.herongyang.com/Service/Hello_WSDL_11_SOAP.wsdl.
/** * Axis2ServiceClientHello.java * Copyright (c) 2009 by Dr. Herong Yang, herongyang.com * All rights reserved */ import java.io.PrintStream; import java.net.URL; import javax.xml.namespace.QName; import org.apache.axis2.client.ServiceClient; import org.apache.axis2.context.ConfigurationContext; class Axis2ServiceClientHello { public static void main(String[] args) { PrintStream out = System.out; // Setting initial values ConfigurationContext config = null; String wsdl = "file:///C:/herong/Hello_WSDL_11_SOAP.wsdl"; String tns = "http://www.herongyang.com/Service/"; String serviceName = "helloService"; String portName = "helloPort"; try { // Creating a dynamic service client with a given WSDL ServiceClient client = new ServiceClient( config, new URL(wsdl), new QName(tns, serviceName), portName); // Printing ServiceClient object information out.println(); out.println("ServiceClient object information:"); out.println(" client: "+client); out.println(" client.getAxisConfiguration(): " +client.getAxisConfiguration()); out.println(" client.getAxisService(): " +client.getAxisService()); out.println(" client.getOptions(): " +client.getOptions()); out.println(" client.getServiceContext(): " +client.getServiceContext()); out.println(" client.getTargetEPR(): " +client.getTargetEPR()); } catch (Exception e) { e.printStackTrace(); } } }
Compilation and execution of this program are described below:
C:\herong>\local\jdk\bin\javac -Djava.ext.dirs=\local\axis2\lib\ Axis2ServiceClientHello.java C:\herong>\local\jdk\bin\java -Djava.ext.dirs=\local\axis2\lib\ Axis2ServiceClientHello log4j:WARN No appenders could be found for logger (org.apache.axis2.description.WSDL11ToAxisServiceBuilder). log4j:WARN Please initialize the log4j system properly. ServiceClient object information: client: org.apache.axis2.client.ServiceClient@1 client.getAxisConfiguration(): org.apache.axis2.engine.AxisConfiguration@148bd3 client.getAxisService(): helloService client.getOptions(): org.apache.axis2.client.Options@e80842 client.getServiceContext(): org.apache.axis2.context.ServiceContext@17653ae client.getTargetEPR(): null
