How to invoke a service using a common class interface

[wang feng]

Hi,all
    I has a scenario as below.
    When get a service,I want to use a common service class such as 
'ServiceInvoker'.
    The use of the common class like a class reflect.

ServiceInvoker.java
public interface ServiceInvoker{
        Object  invoke(String methodName,Class[] argType,Object[] args);
}

Calculator example:
CalculatorService calculatorService = 
scaDomain.getService(CalculatorService.class, "CalculatorServiceComponent");
double res = calculatorService.add(3.0, 2.0)

To
ServiceInvoker invoker =  scaDomain.getService("CalculatorServiceComponent");
Object res = invoker.invoke("add",new Class[]{Double.class,Double.class},new 
Double[]{2.0,3.0});

How can I do for this,anyone has advice.
                                
Thanks
Wang Feng
