Jar and java.library.path
提问by skiwi
I am trying to use DLL's from a specific place from the disk (because I am using JNotify library).
我正在尝试从磁盘的特定位置使用 DLL（因为我使用的是 JNotify 库）。
Using Netbeans 7.4, the following happened:
使用 Netbeans 7.4，发生了以下情况：
My temporary program only does:
我的临时程序只做：
System.out.println(System.getProperty("java.library.path"));
System.out.println(System.getProperty("java.library.path"));
As VM options in Netbeans I have set: -Djava.library.path=D:/JNotify-dll/. Program outputs: D:/Jnotify-dll/.
作为 Netbeans 中的 VM 选项，我设置了：-Djava.library.path=D:/JNotify-dll/. 程序输出：D:/Jnotify-dll/.
When I run it as normal java <jarfile>: It gives main class not set, while I did set it in Netbeans options.
当我正常运行它时java <jarfile>：它没有设置主类，而我确实在 Netbeans 选项中设置了它。
When I run it as java -jar <jarfile>: It gives me my %PATH%variable.
当我运行它时java -jar <jarfile>：它给了我我的%PATH%变量。
When I run it as java -jar <jarfile> -Djava.library.path=D:/JNotify-dll/it stillgives me my %PATH%variable.
当我运行它时，java -jar <jarfile> -Djava.library.path=D:/JNotify-dll/它仍然给我我的%PATH%变量。
Does anyone have any clue what is going on? I am getting real tired of it.
有谁知道发生了什么？我真的厌倦了。

EDIT:java -jar -Djava.library.path=D:/JNotify-dll/ <jarfile>, but I'd still appreciate an answer.
