Exception when using binding.ws instead of binding.sca. Interface contains only methods without
any in/out parameters and return values
---------------------------------------------------------------------------------------------------------------------------------------

                 Key: TUSCANY-2059
                 URL: https://issues.apache.org/jira/browse/TUSCANY-2059
             Project: Tuscany
          Issue Type: Bug
          Components: Java SCA Core Runtime
    Affects Versions: Java-SCA-1.1
         Environment: Windows XP SP2, Intel Core 2 CPU, 2.6, 2GB Ram, jdk 1.5.0_10 
            Reporter: Daniel Stucky


I have the following Java Interface that works with binding.sca:

public interface Gamma
{	
	void start();			
	void doSomething();
	void stop();
}

When I use binding.ws (I let Tuscany create the WSDL interfaces automatically), I get the
following exception (see below):
If I add a parameter (e.g. int x) to any of the methods or I replace any return type void
by a type (e.g. int) it works.
Does WSDL not allow services without any In/Out parameters ?

I also tried it with version 1.2, the exception changed to this:
