To fix this issue JavaBeans as widget component
(I am learning Java and Java beans)
code :
ZoneId z = ZoneId.of( "Africa/Tunis" ) ;
LocalTime lt = LocalTime.now( z ) ;
ZoneId z = ZoneId.systemDefault() ;  // Get JVM’s current default time zone.
LocalTime lt = LocalTime.now( z ) ;
String input = "23:01:23" ;
LocalTime lt = LocalTime.parse( input ) ;
Locale locale = Locale.CANADA_FRENCH ;
DateTimeFormatter f = DateTimeFormatter.ofLocalizedTime( FormatStyle.MEDIUM ) ;
package org.example;

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.time.DateTimeException;
import java.time.LocalTime;
import java.time.ZoneId;
import java.time.format.DateTimeFormatter;
import java.time.format.FormatStyle;
import java.util.Locale;

 * Hello world!
public class App extends JFrame
    ZoneId zoneId;
    LocalTime localTime;
    JTextField timeZone;
    JLabel displayTime;
    DateTimeFormatter formatter;

    public App ( )

    private void initUI ( )

        setTitle( "Simple example" );
        setSize( 300 , 200 );
        setLocationRelativeTo( null );
        setDefaultCloseOperation( EXIT_ON_CLOSE );

        // Widgets
        this.zoneId = ZoneId.systemDefault();
        this.timeZone = new JTextField( this.zoneId.getId() , 20 );
        this.localTime = LocalTime.now( this.zoneId );
        Locale locale = Locale.CANADA_FRENCH;
        this.formatter = DateTimeFormatter.ofLocalizedTime( FormatStyle.MEDIUM );
        this.displayTime = new JLabel( this.localTime.format( this.formatter ) );

        this.timeZone.addActionListener( new ActionListener()
            public void actionPerformed ( ActionEvent event )
                System.out.println( "The entered text is: " + timeZone.getText() );
                    zoneId = ZoneId.of( timeZone.getText() );
                    localTime = LocalTime.now( zoneId );
                    String output = LocalTime.now( zoneId ).format( formatter );
                    displayTime.setText( output );
                catch ( DateTimeException e )
                    System.out.println( "BAD INPUT - The user gave an invalid time zone: " + timeZone );
        } );

        // Arrange
        JPanel panel = new JPanel();
        panel.add( this.displayTime );
        panel.add( this.timeZone );
        this.add( panel );

    public static void main ( String[] args )

        EventQueue.invokeLater( ( ) -> {

            var ex = new App();
            ex.setVisible( true );
        } );

wish of those help What you are doing is wrong!
You are binding the form with a list of Users instead of the User object.
code :
 public ModelAndView getUserList(ModelMap model){
    List<User> userList = userService.getUserList();        
    ModelAndView model = new ModelAndView("userList");
    model.addAttribute("userList", userList);
    model.addAttribute("user", new User());
    return model;

STS reports error in bean config for java.sql.Date property

will be helpful for those in need At this time, I can only see 3 situations where the code "would work", in the order of their likeliness to happen:
the parent bean where the property is injected is defined with scope="prototype" or lazy-init="true" and is not accessed at all the runtime classpath contains an implementation of java.sql.Dateshadowing the original that particular context xml is not used in the application
code :
Could not instantiate bean class [java.sql.Date]: No default constructor found; nested exception is java.lang.NoSuchMethodException: java.sql.Date.<init>()

Does a non-Bean Managed Property NOT update in Target Bean with change in the Property in Source Bean in JSF? The same m

will help you Apparently you're referencing the target bean's property directly instead of the target bean itself.
The below is indeed wrong:
code :
private String otherBeanProperty;
private OtherBean otherBean;

how to store date from html form using datepicker in bean class property(java.util.Date)

By : plksf mnrt
Date : March 29 2020, 07:55 AM
wish of those help The problem is that when you use the Materialize framework, they create the date as a string instead of the Date object. You need to take the string and convert it to a Date object if that's how you want to store it.
To do this in Java, you can use the DateFormat object first like this:
code :
String strDate = "06/04/1992";
DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
Date date = dateFormat.parse(strDate);


// Output
Thu Jun 04 00:00:00 CDT 1992
String newDateObjectAsString = dateFormat.format(date);

// Output
String strDate = "06/04/1992";
DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
Date date = null;
try {
    date = dateFormat.parse(strDate);
} catch (ParseException e) {

String newDateObjectAsString = dateFormat.format(date);

var parts ='04/03/2014'.split('/');
//please put attention to the month (parts[0]), Javascript counts months from 0:
// January - 0, February - 1, etc
var mydate = new Date(parts[2],parts[0]-1,parts[1]);
