Try something like :
=======================================================================
package tavant.aspect;

public aspect MyAspect {
       pointcut myPtCt() : 
       call (public *..*ResponseSDO *..*.*Service(*..*RequestSDO));

       before() :  myPtCt() {
		System.out.println("Going To Call a Service Method");
       }
}
=======================================================================


I wrote a service class :
=======================================================================
package tavant;

public class HelloService {
    public HelloResponseSDO myService(HelloRequestSDO arg) {
	return null;
    }

    public static void main(String[] args) {
	HelloService service = new HelloService();
	service.myService(null);
	System.out.println("Done!");
    }
}

class HelloResponseSDO {
}

class HelloRequestSDO {
}
=======================================================================
and compiling both files with ajc worked for me.

Cheerio,
