Flow in my project works like this. When user request one web page, action method searchPm will execute. This calls populatePm method in service call. Then it will call some dao methods. I have JavaBean as a property in action class. This java bean get populated in service(dao) and return from the service class to action class. The same JavaBean got the List property which is populated in service class.
The above is my flow. But I have another doubt. I think I didn't understand struts properly. If validation fails, does it calls the action method or just execute method. I think it shouldn't call any of those, because while editing the form assume you have changed some form values. And submit the form but validation fails and you will see the same form with error messages and changed values as well not the old values. Is that right. Correct me if i am wrong.
