How to send form input values and invoke a method in JSF bean
(1 answer)
Closed 5 years ago.
I have a JSF project, and I am trying to do a login page, in my project I have a managed bean that has a validate method for the username and password, and I have a bean class with setters and getters which has the user info that get filled for a database eg.(username, password, isActive, Full name), my question is how can I call the user info in JSF el expression in my xhtml pages if they are not in the managed bean?
Here is my java bean:
#Table(name="students_info")
public class User {
#Column(name="std_record_id")
private int id;
#Column(name="std_id")
private String userId;
#Column(name="first_name")
private String firstName;
#Column(name="web_password")
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
And here is my MBLogin:
#ManagedBean
#SessionScoped
public class MBLogin {
User user = new User();
LoginDAO loginDao = new LoginDAO();
public String validteStudent() {
boolean valid = loginDao.validateStudent(user.getUserId(), user.getUserId());
if (valid) {
HttpSession session = SessionUtils.getSession();
session.setAttribute("username", user);
return "student";
} else {
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_WARN,
"Incorrect Username and Passowrd", "Please enter correct username and Password"));
return "login";
}
}
}

Answer 1

Add a getter for the user:
#ManagedBean
#SessionScoped
public class MBLogin {
User user = new User();
LoginDAO loginDao = new LoginDAO();
public String validteStudent() {
boolean valid = loginDao.validateStudent(user.getUserId(), user.getUserId());
if (valid) {
HttpSession session = SessionUtils.getSession();
session.setAttribute("username", user);
return "student";
} else {
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_WARN,
"Incorrect Username and Passowrd", "Please enter correct username and Password"));
return "login";
}
}
public User getUser() {
return user;
}
}
Then in your xhtml you can call it like this:
#{user.id}, #{user.firstName}
