Problem with Tomcat

[MaRiOs]

Well the time came to test tomcat for first time.
one of our new clients installed a script that connects to a mysql database.

the result he gets its :

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

I think its clear that the problem is in the 1st line :

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
is there any driver for plesk ? or do i have to search it from sun's site and dl/install it ?

I have found info about the connector here :
http://dev.mysql.com/doc/refman/5.0/en/cj-system-requirements.html
and installation instruction but im not sure that it needs install or if ti will damage plesk in any way.

Is there anyone that had used this ?
