using a native dll in java

Hey people

i am using eclipse and i tried to use jacob to run the following code,
which links java to this scripting language called autoit.

package core;
import com.jacob.com.*;
import com.jacob.activeX.*;
import java.util.*;
import java.io.*;

public class Index {

    /**
     * @param args
     */
    public static void main(String[] args) {

        try{
               Runtime.getRuntime().exec("regsvr32.exe /s AutoItX3.dll");
            } catch (IOException ex){
               ex.printStackTrace();
            }
            ActiveXComponent AutoIt3 = new
ActiveXComponent("AutoItX3.Control");
            AutoIt3.invoke("Run","notepad.exe");

    }

}

I set the parameters in run>arguments>vm arguments

-Djava.library.path=<G:\mainpath\AutoItX3.dll>
-Djava.library.path=<G:\mainpath\jacob.dll>

and i added the jacob.jar file to the classpath

But i still get a runtime error,

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jacob 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 com.jacob.com.LibraryLoader.loadJacobLibrary(LibraryLoader.java:
57)
    at com.jacob.com.JacobObject.<clinit>(JacobObject.java:150)
    at core.Index.main(Index.java:20)

Oh.. and placing the dll's in the c:/windows/system folder doesnt help
and i also added the dll to the java/jre/bin/ext and that doesnt help
iether

I have been searching the net , trying to figure out whats going wrong
please could you help me out

thanx
