Unsafistied link error help [message #718946]

Hi I am trying to build a program and am getting the runtime error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: mywrapperclass.nativemethod()V

So my earlier problem was trying to specify where to load a custom dll from, I got around this by placing the .dll in the System32 folder.

Now my problem is when I call a native method in the wrapper class from my main it gives this runtime error. I have looked around on many forums and blog/websites and haven't been able to fix this. Debug and my browsing have me led me to thinking that the problem lies in the project not being able to find the native methods within the dll.

I have been beating my head against a wall for a week trying to build this simple program.. I know a fair amount of Java, but have never worked with interfacing and am still new to eclipse.

Thanks in advance
