I have another problem.

My webservice is a methode that takes an object of type "Dmex" in the mysql data base (with Hibernate).

public class DmexWs implements IDmexWs {

 SessionFactory sessionFactory = new Configuration().configure ().buildSessionFactory();

 public String getDmex(int id) throws RemoteException {
 CommonManager cm = HibernateEnviron.getCommonManager();

 Dmex dmex = (Dmex)cm.findOneId(Dmex.class, 792);

 return dmex.getDescription();

 }

}

And when I run the client, I have this error:

java.rmi.RemoteException: Call invocation failed with code [Client] because of: JDBC Driver class not found: com.mysql.jdbc.Driver; nested exception is:

Must I put the mysqlConnector jar with my class DmexWs in the .war deployed on the server?
