Question

I want to learn that if I can define user input parameters at bean class and take these input parameters from a controller function with submit button :

for example input
jsp :

<h:inputSecret value="#{control.userObj.pwrd}"></h:inputSecret>
   <h:commandButton type="submit" value="Giris" action="#{control.check}">
</h:commandButton>

“User” bean class :

  private String userName;   (with getter and setter)

“Control” controller class :

 private User userObj;

Answer 1

When using nested bean properties, then you need to prepare it yourself so that JSF can call the setters on it. JSF/EL namely won’t prepare them for you.

public class Control {

    private User userObj;

    @PostConstruct
    public void init() {
        userObj = new User();
    }

    // ...
}

This way #{control.userObj.userName} will work in input fields.
