Saving Edited Data From JTable Into Database

Jul 16, 2014

I've tried everything but in vain..I want to save the data from the table into the database, I can easily connect to the database. All I want is how to get the values from the table. I've tried this method to get the values but its not working because of the contructor error in the BgTableModel class.

Tried Method
public void writeBgEdu() {
int last=gtm.getRowCount();
System.out.println(last);
for( int i=0;i<last;i++) {
if(((String) gtm.getValueAt(i,0))!=null)

Swing/AWT/SWT :: Saving And Loading Data Of Jtable

Apr 6, 2015

I am trying to make a program where a user can enter guests name for a hotel, the JTable includes rows for the name of the tenant, the room number, month etc.

I've made the table, however I am having some trouble in saving the data that I put into the table. I used jtextfield and a jbutton to but data into the jtable. I am trying to save the data, and load it just buy clicking a button.

table.setModel(new DefaultTableModel(
new Object[][] {
},
new String[] {
"Room", "Name", "Month", "Payment"//table rows
}
));

This is my basic table. And what I'm trying to do to save the data is:

DefaultTableModel model = new DefaultTableModel();
private JFileChooser myJFileChooser = new JFileChooser(new File("."));
private void saveTable() {
if (myJFileChooser.showSaveDialog(null) ==
JFileChooser.APPROVE_OPTION ) {
saveTable(myJFileChooser.getSelectedFile());

[Code] ....

When I run my program, I'm able to click on a button, and the dialog box will appear, I'm also able to save the data to a file. However when I click on the retieve data button I made the dialog box opens, the file is there, however when I click it, nothing happens.

Code Not Saving Data To Database

Nov 2, 2014

I have a simple project to save data to the database. I have successfully mapped the java class with the database table. The code displays no error, it runs very well but it does not save to database, instead it catches an exception and prints out "saving failed". The database is a mysql database.

This is the managed bean code. Save.java(name=bean)
 
//imports
 
@ManagedBean(name="bean")
@RequestScoped
public class Save { 
private String username,password,msg;
Session session = null;
Transaction transaction = null;
//GETTERS AND SETTERS
public Save() {

Saving Data Using Java

Sep 18, 2014

So I'm still learning how to save data using Java. I know that saving data is extremely important when it comes to creating video games.

What I have here is this simple program.

Java Code:

import java.util.*;
import java.io.*;
import java.lang.*;
public class Character
{
private Formatter x;
private int roomNum;
private boolean[] visited = new boolean[10];

[Code]...

I'm trying to make sure that after I exit the program, joe starts in room 4, not room 1, and that he has visited rooms 1, 2, 3, 4, and 10. I have the save data created, but how do I save an array of boolean values?

JTable Filled From Database

Oct 9, 2014

Im building a program that tracks overtime for employees. Basically there will be a list of employees. Number will be dynamic as different departments will have different amounts of employees.A user could pick the department from a JCombobox. E.g Quality Control. A Jtable will be populated with the employees from Quality Control.

The problem is this.

The way it will work is the list will be in a specific order. Whoever is at the top of the list will be asked if they want to do overtime. Then they will be moved to the back of the queue. If they do the work or not doesnt matter.How would i go about planning a system like this? Specifically creating a dynamic list that people can be moved up and down and stored persistently. URL...

Swing/AWT/SWT :: Refreshing JTable From Database

May 21, 2014

I want to add a Refresh button to my frame to refresh the data from the database, but I'm not sure how to refresh the data in the jtable. The constructor below initially creates the table and displays the data. Should my button destroy/create the JPanel all over, or is there a single method within the TableModel that will redisplay the data?

class TablePanel extends JPanel {
private Connection con;
private JTable table;
TablePanel() {
try {

Auto Updating JTable From Database

Feb 10, 2015

I'm doing an application which needs a JTable with data from an existing database. I need the table to periodically (I plan to use a Timer) reflect the changes made to the DB (inserting new rows, deleting or updating existing rows) without making the dirty approach of clearing the whole JTable and refilling it again, which is not nice. I need to just add/modify/delete the needed rows, not the whole table.

Swing/AWT/SWT :: How To Get Data From JTextField Over To JTable

Jun 20, 2014

I am trying to get the data entered in a JTextField into a JTable but not clear on how. The LeftPanel is where the button is located and the RightPanel is where the JTable is. I want the actionPerformed to update the row of the JTable but I can't figure out how. There is another class that controls the GUI but did not think it was necessary to include. Also, I am aware that I am getting an error at the addRow line, can't seem to alleviate it.

public class LeftPanel extends JPanel {

private static final long serialVersionUID = -2311952438693382407L;
private RightPanel rPanel;
public LeftPanel(){
Dimension size = getPreferredSize();
size.width = 250;
setPreferredSize(size);

Swing/AWT/SWT :: Refreshing Data In A JTable?

Apr 24, 2014

I have been trying to learn a bit about JTables for a project I want to undertake. I have created a new JFrame in netbeans and added a button. Onclicking the button I want add some data to a JTable model and then output the JTable with the data. When I click the button again I want the same process to happen again and overwrite the previous table being displayed.

I have written the following code below:

import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

[code].....

The problem I have is that when I click the button for a second time the table stays on the screen exactly as it did following the first click. I can see that the data in the model is changing so I am not sure why a new JTable is not drawn.

Capturing User Data Through JTable

Jan 1, 2015

I am developing a quotation generator application using Java. I am using a JTable to capture user input(this input is taken from a database i.e. each cell of the tale will have a combobox where the user can select an input value). when the user is done he/she has to print the quotation as A4 page.

My issue is: Is there a way of doing it besides using the JTable?

Swing/AWT/SWT :: JTable - How To Repaint With Updated Data

Jun 5, 2014

Here's what I would like to happen:

Java/Swing dialog box appears on the user's screenIt allows the user to enter 2 values into labelled text fields (fname/sname)They select a "Click Me" push button which I hope will write the data into the table. But the table does not get refreshed.

If I minimise the dialog box and then open it again, the data still does not appear.

The code I originally built using eclipse/WindowBuilder. I've cut it back and tried to isolate the issue. But I still cannot figure it out.

I've added some diagnostic log messages to ensure that I am seeing the various events I think I need to see and have put code in the action callbacks etc.

import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import java.awt.GridBagLayout;

[Code] .....
