JDBC with mysql server

Question

I installed mysql on windows 2000 pro.
and run mysql as standalone (mysqld --standalone).
so what is the default url address of mysql?
is it localhost:3306?
the following is my coding:
public String validateUser(String inputUserid, String inputPwd)
     String returnString = null;
     String dbUserid = "userid"; // Your Database user id
     String dbPassword = "password" ; // Your Database password
     Connection con=null;
     ResultSet rs=null;
     Statement stmt=null;
     try {
     Class.forName("org.gjt.mm.mysql");
     con = DriverManager.getConnection("192.168.0.4:3306",
                              dbUserid ,dbPassword );
     stmt = con.createStatement();
     String sql= "select USERID from USERTABLE where USERID = '"+inputUserid+"' and PASSWORD = '"+inputPwd+"';";
     rs = stmt.executeQuery(sql);
     if (rs.next())
     returnString = rs.getString("USERID");
     stmt.close();
     catch (ClassNotFoundException e){}
     catch (SQLException eee) {}
     try{
     if (con!=null)     
                         {con.close();}
     catch (SQLException ee) {}
     return returnString ;
Got the error : not Suitable Driver!
why? please help!

Answer 1

try {
Class.forName("org.gjt.mm.mysql");
con = DriverManager.getConnection(
"192.168.0.4:3306",
dbUserid ,dbPassword );Try replacing 'org'gjt.mm.mysql' with
'sun.jdbc.mysql.Driver'i don't have the driver of 'sun.jdbc.mysql.Driver, in which package or where to download?
but the driver of org.gjt.mm.mysql is what i downloaded from mysql.com, which should be suitable for jdbc! and I also try Class.forName("org.gjt.mm.mysql.Driver"). it doesn't work as well.!!
please help!!
and what is the default url address of mysql server?
