Я очень новичок в JApplet и это то, что я сделал это сейчас.Japplet Form получить значение из базы данных
package myform;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import javax.swing.JComboBox;
public class Form extends javax.swing.JApplet {
/** Initializes the applet Form */
public void init() {
try {
java.awt.EventQueue.invokeAndWait(new Runnable() {
public void run() {
initComponents();
}
});
} catch (Exception ex) {
ex.printStackTrace();
}
JComboBox list = new JComboBox();
try
{
String connstr="jdbc:oracle:thin:@localhost:1521/XE";
String uname="epolicia";
String pass="admin";
Class.forName("oracle.jdbc.OracleDriver").newInstance();
Connection connect =DriverManager.getConnection(connstr,uname,pass);
System.out.println("Oracle driver is loaded");
Statement state=connect.createStatement();
ResultSet rs = state.executeQuery("SELECT * FROM ZONE");
while (rs.next()) {
list.addItem(rs.getString(1));
//System.out.println(rs.getString(1));
}
}
catch(Exception ex)
{
list.addItem(ex);
}
}

И я получаю этот выход 
Но значения не отображаются в поле со списком. Мне нужна стоимость, как <option value='<%=rs.getString(1)%>'><%=rs.getString(2)%></option>
Пожалуйста, помогите мне! Заранее спасибо
Я получил его. но можете ли вы сказать мне решение для этого . Я имею в виду, мне нужно, чтобы это было так, где текст combobox будет другим, и это значение будет другим. –
будет возможно или нет .. ?? –
