在我的代码中有对 FileConnection 方法的调用（open、create、mkdir、delete）；所以当启动应用程序时，会有一些问题问我应用程序想要从设备中读取文件。因此，我在正在使用的手机内部搜索是否有用于签署应用程序的证书，然后我在 Java 目录下找到了这些证书。以下是列出的“受信任的证书”：

那么我可以使用其中之一吗？如果是这样，我该如何使用它？

这些是您设备上安装的证书颁发机构的根证书。您需要使用来自这些机构的代码签名证书对您的代码进行签名。这是威瑞信的链接http://www.verisign.com/code-signing/sun-java/index.html

另请阅读有关MIDP 安全性的信息。
