How to fix "UnsatisfiedLinkError"

I'm trying to create Java software that allows me to start a program and control it through ActiveXComponent. In order to use ActiveXCompnent I downloaded a JAR file named "jacob-1.18". When I am in runtime and I try to start the program this exception occurs:
Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no jacob-1.18-x64 in java.library.path
How can I solve this problem?
I tried to follow this solution but the error remains:
UnsatisfiedLinkError with JACOB and jre 1.7
Thanks in advance.

Exception in thread "main" java.lang.UnsatisfiedLinkError: no openalprjni in java.library.path

I'm trying to use Java bindings for the project https://github.com/openalpr/openalpr
When I try to launch the java application i got this exception
Exception in thread "main" java.lang.UnsatisfiedLinkError: no openalprjni in java.library.path
I try to load the library in this way:
System.loadLibrary("openalprjni");
The file named libopenalprjni.so it's in this dir
/Users/mario/Sviluppo/openalpr/src/bindings/java
so i'm trying, with eclipse, to load it with this configuration as a VM argument
-Djava.library.path=/Users/mario/Sviluppo/openalpr/src/bindings/java/ but nothing happens
What i'm doing wrong?

Include the openalpr.dll and the required all other dll files from the binaries to your JRE or JDK bin directory. Then try to compile and run your program.
Worked for me.

for me worked:
System.load("/usr/lib/libopenalprjni.so");

System.LoadLibrary() doesn't find Library

I have a library /home/me/myfolder/mylib.so
and when executing
System.out.println(System.getProperty("java.library.path"));
I get the /home/me/myfolder. But if I try to load it:
System.loadLibrary("mylib");
This error happens:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no mylib.so in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1867)
at java.lang.Runtime.loadLibrary0(Runtime.java:870)
at java.lang.System.loadLibrary(System.java:1122)
at MainClass.main(MainClass.java:11)
Already tried to use mylib.so instead. The library was created from Haskell Code.

On Linux/Unix, I believe it will look for lib<name>.so, so try renaming your library to /home/me/myfolder/libmylib.so, and loading it with System.loadLibrary("mylib");.

Exception in thread "AWT-EventQueue-0"

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no jpcap in java.library.path
is the error I keep getting, do I need to add a path to jcap? or change my configurations?

UnsatisfiedLinkError means that Java cannot find a native library. If you're on Windows, it's looking for jpcap.dll; if it's Linux or OS X, it's probably jpcap.so. You need to set the system property java.library.path to include the directory that contains the library.
For example, if you have jpcap.dll in a directory named C:\MyProject:
java -Djava.library.path=C:\MyProject com.mypackage.MyProgram

Missing file in java.library.path

While compiling a demo from openni i stumbled across this error:

I'm doing this on my mac . And my best guess is that this file libOpenNI.jni.dylib is not in my java.library.path
My question now is: Is this guess right, and how do i add libOpenNI.jni.dylib to my java.library.path in netbeans.
Thx in advance

add this to VM option of the projects
property: -Djava.library.path=/Users/olivierjanssens/Development/Kinect/OpenNI/Lib/
this is where the dylib file
