I have a JTable displaying the content of a table in MYSQL database. I am able also to add a record in my JTable and my database.. The edit and delete operations are only possible in my JTable (the changes are not diplayed to my database). I want to add hibernate code in my buttons events so the changes can be displayed to MySQL database.
Any help will be appreciated.
Here's the class concerned:

Output:
Editing
By default, DefaultTableModel will make all the cells editable, just double click the cell you want to change and it will enter "edit" model.
To save the values back to the database will depend on what approach you want to take, you could override the setValueAt of the TableModel method and push the changes when this method is called, personally, I'd add a Save button and push the changes as a batch
Deleting
This is a little more difficult. The problem is, once you remove one row, all the indices for all the other selected items will change...
A better solution would be devise a hibernate bean/data class and load this via Hibernate. You could then use a custom implementation of the TableModel, extending from something like AbstractTableModel, which would give you management control of the content.
You would then, get all the objects that are selected (this would be a method in your custom TableModel, something like getValueAt(int row) which returned the hibernate object at the specified row) and then pass this to some kind of delete method (ie removeValue(TBiens bean)), firing the appropriate event notifications...
I finally succeeded in deleting and editing rows from my JTable and database.

So I am trying to build a CRUD app, I am able to perform all the operations in a console app and now I want to use the same methods in my GUI application. I have setup all the necessary fields and a table, the add button works and I can implement the others too! my question is how to work with the JTable?
Here is the code for my window builder. You can see that I have set columns for the tables too.
this is what the GUI looks like

This is the actionlistener code
btnStock.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
OrderExample window = new OrderExample();
}
});
I've tried to set window to visible but it just gives me an error.
The class OrderExamplehas all of its functionality in its (static) main method which is never been called by your Actionlistener implementation.
You could simply add the call to OrderExample.main to your Actionlistener implementation, but you should better first move the content of main to a non static method (e.g.: init) and call that.
I am trying to build a quiz app and I managed to build the database. I created a GUI using the card layout to switch between panels and I tried to retrieve the questions and options from from the database to a JtextArea with no success. My question is how do I get the visual components (jtext area,jbutton to display the content from the database) I want them to automatically set the text according with the question number.
this is my code

Since you didn't mention your code, its difficult to give you a short precise example. I would recommend you to go through this tutorial which retrieves information (name and number) and display it in JTextArea.
Extracting the key points from the tutorial below:
Database connection establishment and fetching information
String url = "jdbc:mysql://localhost:3306/";
String db = "databasename";
String driver = "com.mysql.jdbc.Driver";
String user = "xxxx";
String pass = "xxxx";
Connection con = null;
PreparedStatement pstatement = null;
Class.forName(driver).newInstance();
con = DriverManager.getConnection(url + db , user, pass);
pstatement = con.prepareStatement("SELECT name, phonenumber FROM tablename");
con = DriverManager.getConnection(url + db, user, pass);
ResultSet rs = pstatement.executeQuery();
while(rs.next()){
String name = rs.getString(1);
int phonenumber = rs.getInt(2);
}
Set text in JTextArea
Then use setText method of JTextArea to set the text. For example, recordTextArea.setText(name + " " + phonenumber);.
Im trying to filter my Jtabke using my Jcomboox but i cant do it and in the :
http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#sorting
it only says how to filter using search txt field or sort using headers but not how to use a JComboBox change event to filter a JTable is there a simple code to do this??
EDITED
GOT iT WORKING
This is my Code:
public class Sql extends JFrame{
JTable table = new JTable();

st = conn.createStatement();
rs= st.executeQuery("SELECT DISTINCT Nombre_Pdv FROM VENTA_PLATILLOS");
while(rs.next()){
comboBox.addItem(rs.getString(1));
}
}
catch(Exception e){
e.printStackTrace();

Try this, using a TableRowSorter, fill the table with some numbers and filter it ...

import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.RowFilter;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableRowSorter;
public class TableFilter extends JFrame {
private JTable table;
private DefaultTableModel model;
private TableRowSorter<DefaultTableModel> sorter;
public TableFilter() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
initComponents();
pack();
setVisible(true);
}
public static void main(String args[]) {
new TableFilter();
}
private void initComponents() {
JPanel panel = new JPanel();
final JComboBox<String> comboBox = new JComboBox<>(new String[]{"","1","2","3"});
JButton button = new JButton("filter");
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
RowFilter<DefaultTableModel, Object> rf = RowFilter.regexFilter(comboBox.getSelectedItem().toString(), 0);
sorter.setRowFilter(rf);
}
});
panel.add(comboBox);
panel.add(button);
table = new JTable(model = new DefaultTableModel(3,3));
sorter = new TableRowSorter<DefaultTableModel>(model);
table.setRowSorter(sorter);
add(panel,BorderLayout.SOUTH);
add(new JScrollPane(table));
}
}
Fill the table with some numbers
filter it
