Question

我有一个由java web start启动器启动的applet，它也已签名。我需要使用此applet在客户端计算机上执行一些文件操作，这样做会引发异常。下面是完整的堆栈跟踪

以下是正在使用的导致问题的代码。（但我不认为它的代码）

listSaveFile.addAll(Arrays.asList(saveFileArr));
System.out.println("" + listSaveFile);

Collection<File> found = FileUtils.listFiles(new File(sFolderPath),
                         new NotFileFilter(new NameFileFilter(listSaveFile, IOCase.INSENSITIVE)),
                                 TrueFileFilter.INSTANCE);

for (File f : found) {
   try {
           FileUtils.forceDelete(f);
       } catch (Exception e) {
            delFlag = false;
            System.out.println("" + e.getMessage());
       }
 }

请帮忙。提前致谢。
