Re: [aspectj-users] Execution and Call pointcuts
The problem is the target() pointcut. Since you are matching a call join point, the target will be the object on which the method is invoked -- accMgr in your case. However, the type of "s" in advice declaration is MoneyTransfer. So the target() is restricting the selected join points to where the target object is of MoneyTransfer.

The following pointcut fixes that:

pointcut withdrawBefore(MoneyTransfer s, String acc):
  withincode(public void MoneyTransfer.transfer(String)) &&
     call(public void AccountManager.withdraw(String)) &&
        this(s) && args(acc);

Hi Everyone,

I want to pick out a join point that includes a call to an operation from within another operation. The "withincode" join point works fine by itself, but once I add the "call" statement it no longer works. What am I doing wrong?

public privileged aspect MoneyTransferAspect {

pointcut withdrawBefore(MoneyTransfer s, String acc):
   withincode(public void MoneyTransfer.transfer(String)) &&
      call(public void AccountManager.withdraw(String)) &&
         target(s) && args(acc);

before (MoneyTransfer s, String acc): withdrawBefore(s,acc) {

     try {

            System.out.println("before" + acc);
        } catch( Exception e ) { e.printStackTrace(); }
    }
}

public class MoneyTransfer {

   AccountManager accMngr=new AccountManager();

 public void transfer (String acc)
   {
      accMngr.withdraw(acc);
      System.out.println( "MTS: " + acc );
   }
}
