Problem Apache (Kein Zugriff auf Festplatte)

[firestone84]

Hey Leute


also ich habe auf einem Apache Tomcat 5.0.18 eine Javaapplikation laufen .
In diesem Java Programm rufe ich ein externes Programm auf welches hinterher Daten auf der Festplatte speichern soll.

Die Daten werden aber nicht gepeichert

habe auch mit einem einfachen Aufruf

FileWriter out; 			
try{
	out = new FileWriter("C:\\Temp\\test.txt");
	out.write("test");
	out.close();		
}catch(IOException e){
	System.out.println("Fehler");

versucht in eine Datei zu schreiben aber selbst das funktionier nicht .
Wer kann mir helfen

Bitte

Die Java Virtual Machine ermöglicht Zugriffsrechte auf Systemressourcen einzuschränken z.B. Zugriff auf das Dateisystem, Klassen, Sockets oder Attribute der JVM. Diese Einstellungen gelten für alle Anwendungen innerhalb einer JVM.

Die Einstellungen für Tomat findest Du in der Datei $CATALINA_HOME/conf/catalina.policy

Noch mehr Informatioen findet Du hier
http://tomcat.apache.org/tomcat-5.0-...ger-howto.html

Da ich leider nicht so die Ahnung habe poste ich hier einfach mal die Datei

also ich habe einen Windows XP Rechner und Apache Tomcat darauf laufen und möchte das wenn ich meine Java anwendung starte das in die Verzeichnisse C:\Personalausweis\ und C\ geschrieben werden darf also am besten die ganze Partition C ist am einfachsten

hier mal meine catalina.policy

// You can assign additional permissions to particular web applications by
// adding additional "grant" entries here, based on the code base for that
// application, /WEB-INF/classes/, or /WEB-INF/lib/ jar files.
//
// Different permissions can be granted to JSP pages, classes loaded from
// the /WEB-INF/classes/ directory, all jar files in the /WEB-INF/lib/
// directory, or even to individual jar files in the /WEB-INF/lib/ directory.
//
// For instance, assume that the standard "examples" application
// included a JDBC driver that needed to establish a network connection to the
// corresponding database and used the scrape taglib to get the weather from
// the NOAA web server. You might create a "grant" entries like this:
//
// The permissions granted to the context root directory apply to JSP pages.
// grant codeBase "file:${catalina.home}/webapps/examples/-" {
// permission java.net.SocketPermission "dbhost.mycompany.com:5432", "connect";
// permission java.net.SocketPermission "*.noaa.gov:80", "connect";
// };
//
// The permissions granted to the context WEB-INF/classes directory
// grant codeBase "file:${catalina.home}/webapps/examples/WEB-INF/classes/-" {
// };
//
// The permission granted to your JDBC driver
// grant codeBase "jar:file:${catalina.home}/webapps/examples/WEB-INF/lib/driver.jar!/-" {
// permission java.net.SocketPermission "dbhost.mycompany.com:5432", "connect";
// };
// The permission granted to the scrape taglib
// grant codeBase "jar:file:${catalina.home}/webapps/examples/WEB-INF/lib/scrape.jar!/-" {
// permission java.net.SocketPermission "*.noaa.gov:80", "connect";
// };






Wie müsste ich sie jetzt ändern damit ich auf die Verzeichnisse zugreifen darf Sorry für die doofen Fragen aber ich hab da leider keine ahnung von
