Bonjour,

Après quelques recherches sur le forum et dans la FAQ où une méthode est donné, j'aimerais savoir comment vous feriez pour connaitre le type MIME d'un fichier.

J'ai justement utilisé cette méthode, mais pour un fichier audio MP3, cela me renvoie 'unknow' au lieu de "audio/mp3".

Auriez-vous une solution à ce problème ?

Merci d'avance

[tnodev]

salut,

J'ai créé un type enum avec les mime-type associé à leur content type, si cela peut-t'être utile...

yes !! merci je vais regarder ca !!

[sinok]

Bah en java c'ets pas évident, y'a pas de librairies pur qui soit réellement douée pour ça.

Tu as le java activation framework qui fonctionne un peu mieux que la version contenue dans la FAQ et JMimeMagic qui sais déterminer encore plus de types mime mais qui est Buggé (renvoie un OutOfMemoryError sur certains fichiers).

Le plus safe pour moi serait de récupérer une librairie native telle que libsharedmime et de faire les bindings avec JNI et de fournir la version compilée pour chaque OS

[KeKeMaN]

salut,

J'ai créé un type enum avec les mime-type associé à leur content type, si cela peut-t'être utile...

Merci !

Sinon j'ai regardé plusieurs librairies dont une qui me parait pas mal : jmimeinfo.
Je vais voir lors de test plus poussé ...

Merci à tous
