Записки программиста, обо всем и ни о чем. Но, наверное, больше профессионального.

.java.policy


Проверил, работает. Но не обошлось без гамака: нужно, чтобы пользователь явно разрешил доступ к файлам, записав в файл .java.policy нечто вроде
grant {permission java.io.FilePermission "${user.home}/-", "read"; };

private void testReadFile(String filename) {
/* .java.policy
* grant {permission java.io.FilePermission "${user.home}/-", "read"; };
*/
RandomAccessFile file = null;
try{
file = new RandomAccessFile(filename, "r");
byte[] buf = new byte[1024];
int cnt = 0, pos = 0;
while(true){
cnt = file.read(buf);
if(cnt == -1 || cnt == 0){
break;
}
pos += cnt;
}
file.close();
}
catch(IOException ex){
this.log("testReadFile, IO error ["+ex.getMessage()+"]");
}
catch(Exception ex){
this.log("testReadFile, error ["+ex.getMessage()+"]");
}
} // private void testReadFile(String filename) {
