DLL - création - Stabilité

Bonjour à tous,

Alors voilà, j'ai un gros soucis de dll...

J'ai développé un programme assez conséquent qui a un moment donné utilise une DLL ou SO selon l’environnement.

J'utilise JNA pour ma manipulation de librairie sous NetBeans avec un Win 7 - 32bit.

Mon .h en c contient une enum, un union, une structure contenant des foncions de pointeur que j'implémente cotés java et que je passe en paramètre dans deux fonction implémenté en C.

Je fais des testes et cela fonctionne. Je sais utiliser des fonctions écrite en Java et les passer en paramètre d'une fonction C.

Ensuite je le fais dans mon application et là, la JVM(si je ne me trompe pas) crash à tous les coups.

Je fais plusieurs choses avant de charger et manipuler la dll...

Je vais juste vous mettre mon .h et .c et aussi l'équivalent en Java.
Mettre toute mon application ne servirait à rien ^^... Peut-être voir mon bordel :p.

Header h:

Quand je crée la librairie dynamique, j'utilise sous Windows MinGW32 comme compilateur et je fais la commande :
'gcc -Wall -shared a.c a.def -o MyProtocol.dll'

Est-ce que c'est bon comme cela?
Est-ce que mon code C est sufissant ou dois-je rajouter des précisions?
Avez-vous une idée pq cela ne fonctionne pas?

Je suis preneur de tous avis :/

Un grand merci à vous :).

Bon gros problème.

Je dois charger par ma classe ManagementProtocol en tout premier avant de charger comme je le fais dans mon main le controleur et ensuite lui passer ma classe ManagementProtocol...

l'ennuie, c'est que se sont les utilisateurs qui choisissent quels protocoles ils veulent charger...

Une petite aide?


EDIT: Problème trouver dans mon code :).
