ComException 0x8000FFFF; E_UNEXPECTED from generated code

Hello,

I have generated Code from an ocx file using CodegenForComfyJ.bat.

When I run the following code...

public class DirectSkinTest {

    public static void main(String[] args) {
        DefaultLibraryLoader.getInstance().addPath(".");

        ComFunctions.coInitialize();

        final _DWbocx lib = Wbocx.create(ClsCtx.INPROC_SERVER);
        lib.setRootPath(new Int16(1));
    }

}

...I get this exception:

Exception in thread "main" com.jniwrapper.win32.com.ComException: COM object method returns error code: 0x8000FFFF; E_UNEXPECTED (Schwerwiegender Fehler)

    at DirectSkinTest.main(DirectSkinTest.java:19)

What's wrong with my code and how can I fix it?

I have the following setup:

Windows XP

ComfyJ 2.7

comfyj.lic, jniwrap.lic, jniwrap.dll and the ocx file are contained in the directory where the application is executed (which I add in the above method).

The generated code and the ocx file from which it was generated are attached to this post.

Thanks in advance,

ASC
