Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection( "Jdbc:Odbc:mydb", "","");
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select * from users");
while (rs.next()) {
System.out.println(rs.getString("uname") + " "
+ rs.getString("pwd"));
}
} catch (Exception e) {
System.out.println(e);
} finally {
if(con!=null){
try {

try {
stmt.close();
stmt = null;
} catch (SQLException sqlEx) {
sqlEx.printStackTrace();
}

The Exception say it all.
Also look at the method signature and parameters for getConnection method.
