  • @Begnnier, Why do you need to set a native library? – Perdomoff Dec 23 '15 at 15:58
  • @Perdomoff i read that in the link you sent that i should follow steps one of them set the native libraries –  Dec 23 '15 at 16:03
  • Some Java frameworks depend on native code. Does your application depend on another language? Are you trying to add jars to your project? Help me understand what you're trying to do. – Perdomoff Dec 23 '15 at 16:10

Java:

System.out.println(System.getProperty("java.library.path"));

console:

  • @Begnnier What operating system? – Perdomoff Dec 22 '15 at 20:10
  • i checked it now again , there is no error in spaces –  Dec 22 '15 at 20:39
  • What do you get when you type in your console: echo $LD_LIBRARY_PATH – Perdomoff Dec 22 '15 at 22:45
  • @Begnnier, Read this, you may have not set it yet:[java.library.path – What is it and how to use](http://examples.javacodegeeks.com/java-basics/java-library-path-what-is-it-and-how-to-use/) – Perdomoff Dec 22 '15 at 23:24
  • i read it now and what i got that there is another way to set it by iDE and i'm using eclipse and set it already so should i set it again or not ? –  Dec 22 '15 at 23:49
  • @Begnnier, follow the link and then let's try to get that path you set. – Perdomoff Dec 22 '15 at 23:53

You have to follow the symbolic links.

ls -lah /usr/bin/java
/usr/bin/java -> /etc/alternatives/java

ls -lah /etc/alternatives/java
/etc/alternatives/java -> /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
