i'm developing swing application using netbeans 6.5. one of my form this error happen.
Inside showCutomerData method there is a table and i assign values for table fields, and it happen using therad it show below
/// table
public void showCutomerData(int states) {
try {
CustomerQuery custQue1 = new CustomerQuery();
ResultSet rs1 = null;
String data[][] = new String[custQue1.customerCount(states)][2];
rs1 = (ResultSet) custQue1.viewCustomer(states);
int x = 0;
while (rs1.next()) {
data[x][0] = rs1.getString("customerNo");
data[x][1] = rs1.getString("customerName");
x++;
}
String tableHeader[] = {"Customer No ", "Cutomer Name"};
DefaultTableModel model = new DefaultTableModel(data, tableHeader) {
@Override public boolean isCellEditable(int x, int y) {
return false; } };
tabViewCus.setModel(model);
TableColumn colou1 = tabViewCus.getColumnModel().getColumn(0);
TableColumn colou2 = tabViewCus.getColumnModel().getColumn(1);
} catch (Exception ex) {
JOptionPane.showMessageDialog(null, ex);
//System.out.println(ex); }
}
here is thread code and call above method every 1 seconds.
//theard
public void run() {
while (true) {
try {
showCutomerData(1);
} catch (Exception e) {
System.out.println(e);
} try {
Thread.sleep(1000);
} catch (Exception e) {
System.out.println(e);
}
}
}
so after executing this code below exception throws,
