The functions you mention, NPN_Invoke and NPN_GetProperty, are used in  
the other direction. They are for calling from the plug-in to the  
browser to access properties of objects in the webpage. You don’t  
need to use either of them to export properties and methods from a  
plug-in for access from the webpage.
