JDBC Problem

[ahmedshayan]

I have been trying to connect Database in Java for a quit time now. Following is the code. I have worked with .mdb extension, but this time I am using .accdb extension.
Database File.

import java.sql.*;
class DB{
 static Connection con;
 static Statement sta;
 static void getDBConnection(String path)
{
    try{
        System.out.println("-----Requesting the Connection---------");
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        con=DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ="+path);
        sta=con.createStatement();
        System.out.println("------------Connection Established");
    }
    catch(SQLException e)
    {
        System.out.println(e);
        e.printStackTrace();
    }
    catch(ClassNotFoundException e){
        System.out.println(e);
        e.printStackTrace();
    }
    }
public static Statement getStatement(){
    return sta;
}
public static void disconnectDB(){
    try{
        con.close();
        System.out.print("------Connection closed----");
    }
    catch(SQLException e){
        System.out.println(e);
        e.printStackTrace();
    }
}
}

Item File.

import java.sql.Statement;
import java.sql.ResultSet;
 class item
 {
    public void viewItem()
    {
        int col1Value=0;
        String col2Value=null;
        int col3Value=0;
        double col4Value=0.0;
        double total=col3Value*col4Value;
        DB dbConnect = new DB();
        dbConnect.getDBConnection("ZTBL.accdb");
        Statement statement = dbConnect.getStatement();
         String query = "SELECT * FROM item";
         try
         {
             ResultSet resultSet = statement.executeQuery(query);
             while (resultSet.next())
             {
                 col1Value = resultSet.getInt("Item Id");
                 col2Value = resultSet.getString("Item Name");
                 col3Value = resultSet.getInt("Quantity");
                 col4Value = resultSet.getDouble("Total Amount");
        /* Printing the data on the console */
        System.out.println(col1Value+ "    "+col2Value+"   "+col3Value+"  "+col4Value+"  "+total);
      } //end of while
    }//end of try
    catch(Exception exception)
    {
 	System.out.println("Exception while executing the Query: "+exception);
    }
    finally
    {
        dbConnect.disconnectDB();
    }
    }
 }

and Client file.

import java.sql.Statement;
import java.sql.ResultSet;
public class client
{
    public static void main(String[] args)
    {
            item a = new item();
            a.viewItem();
           // stock b=new stock();
            //b.viewstock();
    }
}

Please guys help me out!
