Problèmes à la compilation avec NetBeans
Bonjour,
Je suis actuellement entrain de programmer un projet JEE avec une base de données Derby. Le projet fonctionne, mais à la compilation, NetBeans m'affiche une série d'erreurs ou l'on me parle de fuites de mémoires et des drivers de derby qui m'inquiètent quelque peu :

Je précise également que NetBeans plante régulièrement.
Quelqu'un aurait une solution à ce problème?
Je précise que je me connecte à la base de données Derby avec ce bout de code dans l'init d'un de mes servlets :
Code:
1
2
| Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();
connection = DriverManager.getConnection("jdbc:derby:"+getServletContext().getRealPath("maBase")+";create=true"); |
Et que je quitte la base de données dans le destroy du même servlet :
Code:
connection = DriverManager.getConnection("jdbc:derby:"+getServletContext().getRealPath("maBase")+";shutdown=true");
Voila,
Merci d'avance!
