java target
The run target invokes the Main application, passing it the WSDL URL of the deployed Web service as its single argument. The classpath element adds the
clientclass directory to the CLASSPATH, using the reference created with the
path task.
10.
Execute the run target to invoke the echoComplexType operation: prompt ant run
If the invoke was successful, you should see the following final output: run:
[java] echoComplexType called. Result: 999, Hello Struct You can use the build-client and run targets in the build.xml file to iteratively
update, rebuild, and run the Java client application as part of your development process.
2.4.1 Sample Java Client Application
The following provides a simple Java client application that invokes the echoComplexType
operation. package examples.webservices.simple_client;
import java.rmi.RemoteException; import javax.xml.rpc.ServiceException;
import the BasicStruct class, used as a param and return value of the echoComplexType operation. The class is generated automatically by
the clientgen Ant task. import examples.webservices.complex.BasicStruct;
This is a simple Java client application that invokes the echoComplexType operation of the ComplexService Web service.
public class Main { public static void mainString[] args
throws ServiceException, RemoteException { ComplexService service = new ComplexService_Impl args[0] + ?WSDL ;
ComplexPortType port = service.getComplexServicePort; BasicStruct in = new BasicStruct;
in.setIntValue999; in.setStringValueHello Struct;
BasicStruct result = port.echoComplexTypein; System.out.printlnechoComplexType called. Result: + result.getIntValue
+ , + result.getStringValue; }
}

2.4.2 Sample Ant Build File For Building Java Client Application
The following build.xml file defines tasks to build the Java client application. The example uses properties to simplify the file.
project name=webservices-simple_client default=all -- set global properties for this build --
property name=wls.hostname value=localhost property name=wls.port value=7001
property name=example-output value=output property name=clientclass-dir value={example-output}clientclass
