netbeans jar构建文件无法打开

Question

I have build my project using OpenCV. When I run my project through netbeans it runs fine.. but when I create its jar file via Clean and Build it doesn't open. it displays a message in output screen when it is build that is..

 To run this application from the command line without Ant, try:
 java -jar "C:\Users\Rafi Abro\Documents\NetBeansProjects\WebCam\dist\WebCam.jar"

I also tried to open my project through this command..

 java -jar WebCam.jar

but it displayed error below:

 Exception in thread "main" java.lang.UnsatisfiedLinkError: no opencv_java2410 in
 java.library.path
    at java.lang.ClassLoader.loadLibrary(Unknown Source)
    at java.lang.Runtime.loadLibrary0(Unknown Source)
    at java.lang.System.loadLibrary(Unknown Source)
    at javaanpr.Main.main(Main.java:154)

please can anyone help me through out this problem..

Thanks

Answer 1

This is because you have included VM option path in netbeans. and Netbeans Automatically calls it whenever it is executed.

now when you are trying to run command. ie

java -jar WebCam.jar

there is not path defined in command, thatsy you are getting that error..

try this command:

java -Djava.library.path="C:\OpenCV\opencv\build\java\x86" -jar WebCam.jar

hope this will help you.!
