Jersey Rest Services + mySQL Database : No suitable driver found

I'm developping Jersey services using a mySql Database. I have a maven project which gathers all of this and it works pretty well on my linux. However a coworker is trying to use it under windows and accessing any services will fail with : java.sql.SQLException: No suitable driver found for jdbc:mysql://[hidden_ip_adress_for_topic]:3306/riskdb?zeroDateTimeBehavior=convertToNull We are both using netbeans in which the mySQLConnector is included (according to my invastigations). Our poject is made of 2 modules : Services and Library. In the library there is all the stuff for database managment. And If I try the library's functions, it works well, I can get data from database ! But as soon as I run Glassfish, An internal error 500 with "driver not found" appears. Maybe I didn't understand what is the SQL-connector... Have you got any hint for me ? Thanks !
