Is it possible you are trying to write to a read only file? From the stack trace you are invoking an insert method.
您是否可能正在尝试写入只读文件？从堆栈跟踪中，您正在调用插入方法。
Also, do you have permissions to access the file? I mean read permissions on the file itself as well as on its parent directory (and its parent and so on).
另外，您是否有权访问该文件？我的意思是对文件本身及其父目录（及其父目录等）的读取权限。

Seems like the java-process lacks permission to read the file. You're problaby running with UAC and all that other annoying stuff MS put into Vista.
似乎 java 进程缺乏读取文件的权限。您可能正在使用 UAC 以及 MS 放入 Vista 的所有其他烦人的东西。
I'd do the following:
我会做以下事情：
- Check the files permissions.
- Run the java-code with "Run as administrator"-option
- Turn off UAC and always run everything with admin-rights
- 检查文件权限。
- 使用“以管理员身份运行”选项运行 java 代码
- 关闭 UAC 并始终以管理员权限运行所有内容

From 1.6.0_14 java does something other way than 1.6.0_13 handling virtual paths (symlinks) and windows vista uses them heavily on program files and documents and settings. Maybe this is your problem.
从 1.6.0_14 开始，java 做了一些不同于 1.6.0_13 处理虚拟路径（符号链接）的方法，windows vista 在程序文件、文档和设置上大量使用它们。也许这是你的问题。
