Scott Kurz commented on TUSCANY-1473:
-------------------------------------

This problem looks similar to TUSCANY-1342 which I opened.  I commented there 
that for a remotable interface you can't overload the method names anyway ...  
and WSDL interfaces are always remotable.



> Define component's service with interface.wsdl ,throws 'No matching 
> operation' error.

> I define the component's service with interface.java,the sample runs fine. 
> but when I modify the component's service with interface.wsdl,the sample 
> throws an exception.
> The throwable stack is :
> Exception in thread "main" java.lang.IllegalArgumentException: No matching 
> operation is found: public abstract java.lang.String 
> helloworld.HelloWorldService.getGreetings(java.lang.String)
>       at 
> org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.invoke(JDKInvocationHandler.java:69)
>       at $Proxy10.getGreetings(Unknown Source)
>       at helloworld.HelloWorldClient.main(HelloWorldClient.java:33)
> I look into the code,found the invoke mothod's input type is 'String',but the 
> method which name is 
> operation.getInputType().getLogical().get(i).getPhysical() on the 
> SourceOperation  of the InvocationChain  is always return 'Object' type,so 
> can't find an operation to match.
