import java.sql.*;
public class TestJdbc {
public static void main(String[] arg) {
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:mmall", "","");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select name, age from details;");
while(rs.next()) {
String s = rs.getString("name");
int n = rs.getInt("age");
System.out.println( s + "'s age is :" + n);
} catch(Exception e){
System.out.println(e.getMessage());

It has nothing to do with JDBC.
As a guess you are running the MS VM instead of the sun one.
When you type the following it MUST give you a version number. If it gives you nothing then you are running the MS VM.
java -version
