Untatisfiedlink loading wacom stu-520

Question

I´m working with a pad wacom stu520, i built an applet to get images from wacom pad, but suddenly i became to recieve following error on java console

Exception in thread "AWT-EventQueue-1" java.lang.UnsatisfiedLinkError:               C:\Users\hbernal\AppData\Local\Temp\jna8619986156059459306.tmp: Acceso denegado

I´m loading dll´s with this code snipet

static{
    try{
        System.load("zlib1.dll");       
        System.load("libeay32.dll");                        
        System.load("STUTabletCore.dll");       
    }catch(Exception e){
        e.printStackTrace();
    }
}

I use on my lib jna.jar, jSTUTablet.jar, commons-io-2.1.jar, commons-codec-1.6.jar, i´m using java SDK 1.6.0_37 on Eclipse Kepler.

Thanks in advance

What is the HTML used to load the applet? Can we visit the page? Shouldn't `System.load("zlib1.dll");` be `System.load("zlib1");`? — Andrew Thompson, Jul 13 '13 at 04:41
no matter whether applet is run inside JSF page or run alone, same problem is present — Hernan Bernal, Jul 15 '13 at 13:51
*"no matter whether applet is run inside JSF page or run alone, same problem is present"* If I'd asked "Is it the same behavior when launched with JSF or without?" (which I didn't) that might be a valid & useful reply. I was interested in seeing the class-path as understood by the browser.. — Andrew Thompson, Jul 15 '13 at 13:56

Thanks Andrew:

Finally i found the issue, jna was creating tmp files into a folder where my user haven´t permissions, i have two solutions

change java.io.tempdir
request permissions for my user

Both of them worked like a charm

See ya
