Jar和java.library.path

Question

I am trying to use DLL's from a specific place from the disk (because I am using JNotify library).

Using Netbeans 7.4, the following happened:

My temporary program only does:

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/ .

When I run it as normal java <jarfile> : It gives main class not set, while I did set it in Netbeans options.

When I run it as java -jar <jarfile> : It gives me my %PATH% variable.

When I run it as java -jar <jarfile> -Djava.library.path=D:/JNotify-dll/ it still gives me my %PATH% variable.

Does anyone have any clue what is going on? I am getting real tired of it.

The MANIFEST.MF generated by Netbeans:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.1
Created-By: 1.7.0_25-b17 (Oracle Corporation)

X-COMMENT: Main-Class will be added automatically by build

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

You need to change the order of your command line arguments:

java -Djava.library.path=D:/JNotify-dll/ -jar <jarfile>
