You need to add an PreResultListener to your action:

public class MyInterceptor extends AbstractInterceptor {
  private static final long serialVersionUID = 5065298925572763728L;
    @Override
    public String intercept(ActionInvocation invocation) throws Exception {
      // Register a PreResultListener and implement the beforeReslut method
      invocation.addPreResultListener(new PreResultListener() {
        @Override
        public void beforeResult(ActionInvocation invocation, String resultCode) {
          //dostuff
        }
      });

      // Invocation Continue
      return invocation.invoke();
    }
  }
}

Taken from here.
