Java Database Connectivity (JDBC)

When I try to execute following code:

import java.sql.*;
public class ODBCTest
{
    public static void main(String args[]) throws Exception
    {
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        Connection con = DriverManager.getConnection("jdbc:odbc:razer_s","razer","");
        Statement stmt = con.createStatement();
        stmt.executeUpdate("INSERT INTO test VALUES('1','one')");
        stmt.close();
        con.close();
    }
}

I get this exception:
Exception in thread "main" java.sql.SQLException: [unixODBC][Driver Manager]Data source name not found, and no default driver specified.

My configuration seems to be fine because I can browse
my datasource using DataManager. Does anyone have any suggestions?
