I searched this error in MathGroup and I see there is one that happened 
to Linux.

It is happening to me in Windows Server 2003 x64.  I am trying to call 
MathLinkFactory.createKernelLink()


        String strArg = "-linkmode launch -linkname 'C:\\Program Files 
(x86)\\Wolfram Research\\Mathematica\\6.0\\MathKernel.exe'";
        KernelLink ml = null;

        try {
            ml = MathLinkFactory.createKernelLink(strArg);
        } catch (MathLinkException e) {
            System.out.println("Fatal error opening link: " + 
e.getMessage());
            return;
        }


And I get the following error.

    Fatal error: cannot find the required native library named
    JLinkNativeLibrary.
    Exception in thread "main" java.lang.UnsatisfiedLinkError:

As pointed out in the link above, calling 
MathLinkFactory.createKernelLink(""); gives the same error.

I see that the JLinkNativeLibrary.dll is in 
Mathematica\6.0\SystemFiles\Links\JLink\SystemFiles\Libraries\Windows-x86-64.  
How can make JLink work without this error?

Thank you.
