****************************

<?xml version="1.0" encoding="UTF-8"?>
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0" xmlns:sample="http://sample" name="Calculator" targetNamespace="http://sample">
<service name="CalculatorService" promote="CalculatorServiceComponent/CalculatorService">
<interface.java interface="calculator.CalculatorService"/>
<binding.ws uri="http://localhost:8181/CalculatorService"/>
</service>

<component name="CalculatorServiceComponent">

<implementation.java class="calculator.CalculatorServiceImpl"/>
<reference name="addService" target="AddServiceComponent"/>
<reference name="subtractService" target="SubtractServiceComponent"/>
<reference name="multiplyService" target="MultiplyServiceComponent"/>
<reference name="divideService" target="DivideServiceComponent"/>
</component>
<component name="AddServiceComponent">
<implementation.java class="calculator.AddServiceImpl"/>
</component>
<component name="SubtractServiceComponent">
<implementation.java class="calculator.SubtractServiceImpl"/>
</component>
<component name="MultiplyServiceComponent">
<implementation.java class="calculator.MultiplyServiceImpl"/>
</component>
<component name="DivideServiceComponent">
<implementation.java class="calculator.DivideServiceImpl"/>
</component>
</composite>
***********************************

My CalculatorClient.java:
*********************

public class CalculatorClient {
public static void main(String[] args) throws Exception {

SCADomain scaDomain = SCADomain.newInstance("Calculator.composite");
CalculatorService calculatorService = ???????????;

// Calculate
System.out.println("3 + 2=" + calculatorService.add(3, 2));
System.out.println("3 - 2=" + calculatorService.subtract(3, 2));
System.out.println("3 * 2=" + calculatorService.multiply(3, 2));
System.out.println("3 / 2=" + calculatorService.divide(3, 2));

scaDomain.close();

Hi,

CalculatorService calculatorService =
scaDomain.getService(CalculatorService.class, "CalculatorServiceComponent");

Have a look at [0] ;-)
