Transfer Process:

1. if you click to connect to the Jsp page, the transfer process is xxx. action request --> action --> Jsp. You must use action before entering the jsp page. Therefore, the component parameter must be blank in action. In this case, the default parameter should be set! When programming so, you should first determine whether the searchobject is empty!

2. If you query through the buttons on the Jsp page, the process Jsp --> action --> result is returned to Jsp. Therefore, the serchobject is not empty and can be processed properly according to the logic!
