When I try to do a reverse engineering from jdbc connection, I have a GenericJDBException with an under Exception that ask if MySQL is running.
I don't understand, because MySQL is running on the good default port of my localhost.

Hibernate version:3.0

Name and version of the database you are using:
MySql 4.1.9-max

hibernate.cfg.xml
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
<property name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property>
</session-factory>
</hibernate-configuration>

Obviously not. This exception is being thrown from the driver. Try connecting using an admin tool and the same properties specified. Also check your permission - MySql may be shutting you out based on your host etc.

In fact, it is.
The problem was that I used an older version of MySQL driver.
Thanks
