Bonjour voila j'ai un big problème, je ne sais pas si ça vient de la part de nouveaux logiciels que j'ai installé sur mon ordi mais d'un jour à l'autre mon appli Web ne veux plus se démarrer.

J'utilise netBeans avec le serveur d'application glassfishV2 voici l'erreur quand je lance :

Code : Sélectionner tout - Visualiser dans une fenêtre à part

Deployment error:
The Sun Java System Application Server could not start.
More information about the cause is in the Server log file.
Possible reasons include:
 - IDE timeout: refresh the server node to see if it's running now.
 - Port conflicts. (use netstat -a to detect possible port numbers already used by the operating system.) 
 - Incorrect server configuration (domain.xml to be corrected manually) 
 - Corrupted Deployed Applications preventing the server to start.(This can be seen in the server.log file. In this case, domain.xml needs to be modified).
 - Invalid installation location.
See the server log for details.

Si vous pouvez m'aider ça serait vraiment sympa parce que je bloque totalement et j'ai tout un programme inutilisable derrière
