public class ServiceRequest{
//do some thing
}

public class MyService{

public void method1(ServiceRequest request,String str);
//many methods that has a ServiceRequest argument
public Object method2();//none Arguments
}

public class MyInterceptor implements Interceptor {

 public MyInterceptor() {
 super();
 }

 public String getName() {
 return "MyInterceptor";
 }

 public Object invoke(Invocation invocation) throws Throwable {
 try{
 MethodInvocation mi = (MethodInvocation)invocation;
 ServiceRequest request = (ServiceRequest)mi.getArguments()[0];
 //I get the ServiceRequest,do some thing ...
 return invocation.invokeNext();
 }finally{
 System.out.println("GoodBy,MyInterceptor");
 }
 }
 }

now i want to make MyInterceptor to intercept the methods that has a ServiceRequest argument of MyService !
how can i write the jboss-aop.xml

Thanks...very much....
