hi jus a sample code
public class DbUtil {
// Connection instance
private static Connection conn = null;
private Object connection;
public DbUtil() {
     // Connect to the database
dbConnect();
* This method performs the clean up action and closes the application
void exitDbUtil(){
// If connected to database
if (conn != null) {
try {
// Close the connection
conn.close();
conn=null;
catch (Exception ex){      // Trap errors
System.out.println(" Error while Closing the connection: "+ex.toString());
* Creates a database connection object
private void dbConnect() {
try {
String driverName = "oracle.jdbc.driver.OracleDriver";
Class.forName(driverName);
String url = "jdbc:oracle:thin:@" + ConnectionParams.s_hostName +
          ":" + ConnectionParams.s_portNumber +
          ":" + ConnectionParams.s_databaseSID;
// Create a connection object
conn = DriverManager.getConnection(url, ConnectionParams.s_userName,
                         ConnectionParams.s_password);
catch(Exception e){
