about COM _Enums

Hi all,

     I encounter problem about how to map COM _Enums
to
Java Enumerations.
     My java stub codes for a dll are generated by
JawinTypeBrowser.
     Please have a look following code:

    public IUnknown get_NewEnum() throws COMException
    {
         return (IUnknown)get("_NewEnum");
    }

    I have no idea how to use this 'IUnknown',
actually
I expect this method will return a type of java
Enumerations.
    I am not family with COM _Enums, anyone pls give
me
a help, thanks a lot!

Best regards,
Ken
