Solution 1:[1]

You need the jacob-1.14.3-x86 library on your java library path.

On windows, this would be jacob-1.14.3-x86.dll.

This is a binary file which is used by java to run native methods. It's probably required by some library (jar) you're using.

In here you can see not only a jar, but also the binary required by the jar. Pick the one for your platform.

To quote http://www.velocityreviews.com/forums/t143642-jni-unsatisfied-link-error-but-the-method-name-is-correct.html:

There are two things that cause UnsatisfiedLinkError. One is when System.loadLibrary() fails to load the library, the other is when the JVM fails to find a specific method in the library. The text of the error message itself will indicate which is the case...

The error which you describe clearly cannot find the library at all. As the others have said, include it in your Java library path.

The other error—when the library can be found but the method within the library is not found—looks as follows:

java.lang.UnsatisfiedLinkError: myObject.method([Ljava/lang/Object;)V

In this case you either have the wrong method name, or will have to go back and add the method and recompile the code...
