I have a combobox that the value is shown instead of Id. id should be then insert into a database. I added a listener to combobox to get the Id. By sysout I can see but how could I insert into database????
here is the code:
public void comboboxpersonneldata() {
comboboxpersonnellist = FXCollections.observableArrayList();
handler = new DBHandler();
connection = handler.getConnection();
try {
rs = connection.createStatement().executeQuery("SELECT num_personnel,nom_personnel FROM personnel");
while (rs.next()) {
// comboboxpersonnellist.add(rs.getInt(1));
comboboxpersonnellist.addAll(new comboboxPersonnel(rs.getInt(1), rs.getString(2)));
}
combopersonnel.setItems(comboboxpersonnellist);
combopersonnel.valueProperty().addListener((obs, oldval, newval) -> {
if (newval != null) {
System.out.println(newval.getNum_personnel());
}
});
} catch (SQLException e) {
e.printStackTrace();
}
try {
rs.close();
connection.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
and the model class:
public class comboboxPersonnel {
int num_personnel;
String name_personnel;
public comboboxPersonnel(int num_personnel, String name_personnel) {
this.num_personnel = num_personnel;
this.name_personnel = name_personnel;
}
public int getNum_personnel() {
return num_personnel;
}
public String getName_personnel() {
return name_personnel;
}
#Override
public String toString() {
return name_personnel;
}
}

So I'm making a simple chat where I'm sending content in the form of objects, in this case my problem is that when I'm sending and Image it just blocking my Client!, here's my shortened code.
I've isolated it mostly to the code below, as I've tested the rest and worked fine, I've also tried debugging this but I just can't seem to find the problem

I had a look for RCP specific information on this problem, but the answers relate to setting an SWT element to null. As you can see I am not setting a value, just calling readAndDispatch().
Any ideas?
Okay what I am trying to achieve here is parsing a json string and separating its fields and assigning them to variables. Next I am creating a builder to send data to the elastic for indexing. But I am getting this error which is really bugging me. I am unable to move forward.

Whenever I update the data within the table, the updated data is not reflected. The updated data is reflected only when I reopen the window.
Kindly help me through.
Thanks in advance.
why voids for DefaultTableModel and JTableHeader are static
remove rows from DefaultTableModel
use DocumentListener instead of KeyListener for RowFilter
why is there initialized two different LookAndFeels
updates to DefaultTableModel must be done on EDT, more in Oracle tutorial Concurrency in Swing - The Event Dispatch Thread
search for ResultSetTableModel, TableFromDatabase, BeanTableModel
rest of issue is hidden in shadowing void or classes, note remove all static declare, there should be static only main class
Hi I was doing a list of online users names using JLabel inside the JTextPane.
I used JLabel because I want the names to be clickable I was able to allign them horizontally using the styleddocument now my problem is
How can I delete the JLabel that was recently inserted ? I tried the remove method of JTextPane but it didnt work. I need to delete the JLabel when a user go offline.
My code:
public static void getUsernames()
{
try{
String query = "SELECT username FROM members WHERE status = 'offline'";
ps3 = con.prepareStatement(query);
rs2 = ps3.executeQuery();
}catch(Exception ex){ex.printStackTrace();}
}
public static void resultGetUsername(JTextPane jtp,StyledDocument sd)
{
try {
while (rs2.next())
{
final JLabel jl = new JLabel(rs2.getString("username"));
final String username = rs2.getString("username");
Border d = BorderFactory.createEmptyBorder(1,10,1,10);
Border d2 = BorderFactory.createLineBorder(Color.BLACK);
Border d3 = BorderFactory.createCompoundBorder(d2,d);
jl.setFont(new Font("Calibri",Font.BOLD,16));
jl.setBorder(d3);
jl.setOpaque(true);
jl.setBackground(Color.ORANGE);
jl.addMouseListener(new MouseListener(){
public void mouseClicked(MouseEvent arg0) {
}
public void mouseEntered(MouseEvent arg0) {
jl.setForeground(new Color(30,144,255));
}
public void mouseExited(MouseEvent arg0) {
jl.setForeground(Color.BLACK);
}
public void mousePressed(MouseEvent e) {
jl.setForeground(new Color(210,105,30));
jl.setBackground(new Color(154,205,50));
}
public void mouseReleased(MouseEvent e) {
jl.setBackground(Color.ORANGE);
jl.setForeground(Color.BLACK);
if(e.getClickCount() ==2)
new OneToOneChat(username);
}
});
Cursor c = new Cursor(Cursor.HAND_CURSOR);
jl.setCursor(c);
jtp.insertComponent(jl);
sd.insertString(sd.getLength(), "\n", SubPanel1.sas);
}
} catch (SQLException e) {
} catch (BadLocationException e) {

You can remove the labels from the JTextPane by using
setText("") or getStyledDocument().remove(0, doc.getLength())
if you need to get the labels this post could help: Get a component from a JTextPane through javax.swing.text.Element?
Then add the labels you want back into the JTextPane
