Mysql connection with JDBC

Question

I have followed the advice given here for several
other people and have successfully set up a connection
to a MySQL database. I can successfully test the
database connection from the Connection Wizard.
However, I am having trouble accessing this same
connection from my code. When executing the following
piece of code:
try
          Class.forName("org.gjt.mm.mysql.Driver");
I get a ClassNotFoundException.
The advice in the JDeveloper "help" is not that clear.
I have tried registering this driver with the project,
by configuring the connection as a library and adding
this library into the "Project Settings". I've also
added in the database connection in Tools->Preferences.
Finally, I've tried using File->Import->Existing Sources
and choosing the library I created for the mysql Jar
file. None of this works... am I following the correct
procedure, or is there something I've missed?

Answer 1

the mysql jdbc driver : org.mm.mysql.Driver (you can find it on www.gjt.org)
the url : jdbc:mysql://host:port/dbname
obtain a connexion:
Class.forName("org.mm.mysql.Driver");
Connection conn = DriverManager.getConnection(url, "username", "password");
