Salut à tous,

J'ai un petit problème je pense.
Lorsque que je fais ceci ça fonctionne mais vu qu'il y a ces lignes en commentaires ça ne renouvelle pas le dernier chemin :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

public File fileChooser()
{
	Preferences prefs = Preferences.userNodeForPackage(FileChooser.class);
	FileChooser.lastPath = prefs.get("LastPath", System.getProperty("user.dir"));
	this.setCurrentDirectory(new File(lastPath));
	if (this.showOpenDialog(null) == JFileChooser.APPROVE_OPTION)
	{
		final double ratio = 0.009900990099009901;
		ZipSecureFile.setMinInflateRatio(ratio);
 
		File file = this.getSelectedFile();
		//file = this.getCurrentDirectory();
		//prefs.put("LastPath", file.getAbsolutePath());
		//file.setWritable(true);
 
		return file;
	}
	return null;
}

Et si j'enlève les // alors j'ai un Exception :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Ce qui correspond à :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

InputStream is = new PushbackInputStream(new FileInputStream(file));

Bonjour,
le message d'erreur indique que le fichier n'est pas trouvé à cause d'un problème de droits :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

java.io.FileNotFoundException: M:\H2O (Accès refusé)

Le fichier est il sur la partition principal de ta machine, es tu le propriétaire du fichier ?
Tu peux essayer de lancer ton application en tant qu'administrateur voir si ça fonctionne.

Salut,

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
File file = this.getSelectedFile();
file = this.getCurrentDirectory();
prefs.put("LastPath", file.getAbsolutePath());

Forcément, ta variable file servant à référencer le fichier sélectionné, et vu que tu l'écrase avec le dossier courant, tu perds le fichier sélectionné. Ensuite, le reste du code, qui fait un new FileInputStream(file) va essayer d'ouvrir un dossier comme si c'était un fichier, ce qui est impossible, voire absurde.

Si tu veux mémoriser dans les préférences le dossier du dernier fichier sélectionné :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
File file = this.getSelectedFile();
prefs.put("LastPath", file.getParentFile().getAbsolutePath());

En effet c'est absurde, en tout cas pour ton code, MERCI, ça fonctionne...
