Adding entity in a ManyToMany relation

[fred2210]

Hi,

I have a ManyToMany relation with Entreprise and Tool :
#Entreprise side

@ManyToMany(mappedBy="entreprises")
public Collection<Tool> getTools() {
 return tools;
}

# Tool side

@ManyToMany
public Collection<Entreprise> getEntreprises() {
 return entreprises;
}

The table (Tool_Entreprise) is well created in MySQL.

But I can't add any tool in the entreprise doing (entreprise and tool being initialized) :

entreprise.getTools().add( tool );

No any record is inserted in the table.
(And no error in jboss/hibernate logs)

When I Insert a record manually in the table with the right ids, I can see the result doing entreprise.getTools(); (It works).

How can I add a tool to an entreprise in Java ??

Thanks,
Fred.
