I want the java code

Question

i have created a jsp page in which there are multiple combos and i want
to select data from a table in the database into these combos so i want ur help plz guys help me if u have the answer

Answer 1

JComboBox cbClock = new JComboBox();
//populate combobox
Vector clockv;
clockv.clear();
clockv.add(new CBName("",""));
//use JDBC to create the conn object
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select clock_no, emp_name from tc_clock_nbr where repair_flag = 1 order by emp_name");
while (rs.next()) {
clockv.add(new CBName(rs.getString("clock_no"), rs.getString("emp_name")));
stmt.close();
cbClock.setModel(new DefaultComboBoxModel(clockv));
To get the selected item out of the combo box:
CBName sel = (CBName)cbClock.getSelectedItem();
System.out.println("key =" + sel.key);
System.out.println("decrip=" + sel.descrip);
// class to store info in drop down
class CBName {
public String key;
public String descrip;
public CBName (String key, String descrip) {
this.key = key;
this.descrip = descrip; }
public String toString() { return descrip; }
}
