Java Database Connectivity (JDBC)

Hi.

I am trying to connect to an db on a hosted Tomcatserver.

I have been told that the MySQL server is working just fine.

When I use this code:

Class.forName( "org.gjt.mm.mysql.Driver" );
Connection conn = DriverManager.getConnection("jdbc:mysql:://db_name","db_user","db_password" );

I get the following error message:

java.lang.ClassNotFoundException: Unable to load class org.gjt.mm.mysql.Driver
