Multi-project Web Service Application

public class SimpleErrorMessage
{
    private String  message;

    }
    
    public  String  getMessage()
    {
        return message;
    }
    
    public  void    setMessage( String msg )

        message = msg;
    }
}

When transmitted the result will be marshalled as
