JDBC Driver for MySQL database which should support JDBC2.0 function

Question

Hi, Guys,
I'm using JDK1.3 and mm.mysql-2.0.4-bin.jar in Windows NT. When I run following program, I got the error: java.sql.SQLException: ResultSet not updatable. (the function rs.last() is working).
Based on the documentation, mm.mysql-2.0.4-bin.jar driver should support JDBC2.0 function, but in fact, it's not. So, what's wrong or where is the correct driver?
Thank you in advance anyway!
import java.sql.*;
import java.sql.ResultSet.*;
import java.util.*;
public class BridgeMysql{
public static void main (String[] args) throws Exception {
String sTable = "test";
try {
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
Connection conMysql = DriverManager.getConnection("jdbc:mysql://localhost/myDatabase?user=user&password=password");
Statement st = conMysql.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
ResultSet rs = st.executeQuery("Select * from "+sTable);
//rs.last();
rs.moveToCurrentRow();
System.out.println("Table "+sTable+" contains "+String.valueOf(rs.getRow())+" rows");
rs.close();
st.close();
conMysql.close();
catch (Exception e)
System.out.println(e);

Thought I might add something interesting I found.
You need to include the field in your primary key. I only have one field in the key so I dont know how it works if you have more than one key.
Makes sense considering Mark stated that you need the primary index defined. Looks like you need the fields as well from the select statement.
Can anyone comment on why this is?
