我想远程访问文件，我正在使用这个代码：

FileObject destn=VFS.getManager().resolveFile(f.getAbsolutePath());
        LOGGER.debug("Object Created" +destn);
        domain, username, password
        UserAuthenticator auth=new StaticUserAuthenticator(domain, userName, password);
        LOGGER.debug("Authenticator Object Created" +auth);

        FileSystemOptions opts=new FileSystemOptions();
        DefaultFileSystemConfigBuilder.getInstance().setUserAuthenticator(opts, auth);


        FileObject fo=VFS.getManager().resolveFile(remoteFilePath,opts);

在这一行我得到一个例外：

org.apache.commons.vfs2.FileSystemException: Could not create file "file:////172.50.33.115/D$/testfile.txt".

我在 Windows 上运行此代码。它是一个网络应用程序。
