The problem is in Mac OS.

问题出在Mac OS上。

No, the problem is not having permission to write to the Library directory of userxyz. Java WebStart is usually more than sufficient, but you should at least follow the approach recommended in Technical Q&A QA1170: Important Java Directories on Mac OS X. Note the distinction between user preferences, user data and application support, each of which is rooted in System.getProperty("user.home"). Note also that, java.util.Preferences uses ~/Library/Preferences/your.qualified.name by default. In addition, there's no reason to use hidden file names.

不,问题是没有权限写入userxyz的Library目录。 Java WebStart通常绰绰有余,但您至少应该遵循技术问答QA1170中推荐的方法:Mac OS X上的重要Java目录。请注意用户首选项,用户数据和应用程序支持之间的区别,每个用户首​​选项都植根于System .getProperty( “的user.home”)。另请注意,java.util.Preferences默认使用〜/ Library / Preferences / your.qualified.name。此外,没有理由使用隐藏文件名。
