Native Library xxx.dll already loaded in another classloader

[eranhauser]

Hi,

I am using Jboss 4.0.3 and I am trying to use my lkgrt.dll.
I call the dll from a jar file inside my ear file and I get the following:
java.lang.UnsatisfiedLinkError: Native Library C:\WINDOWS\lkgrt.dll already loaded in another classloader.
How can I over come this problem?
To load the dll I am using:
public class Lkgrt {

static {
System.setProperty("java.library.path", "c:\\windows");
System.loadLibrary("Lkgrt");

}
...
}

any idea? please help
