convert component to service

[Dhananjay Joshi]

hello,

How can one convert an existing xpcom component into a service.
my base class definition is as follows
#ifndef nsPLE_h__
#define nsPLE_h__
#include "nscore.h"
#include "nsISupports.h"
#include "nsCtlCIID.h" /*file for contract ids*/
/*
 * nsPLE Interface declaration 
 */

class nsPLE : public nsISupports {
public:
  NS_DEFINE_STATIC_IID_ACCESSOR(NS_PLE_IID)
  

  NS_IMETHOD GetGlyphsForText(PRUint32*, PRUint32&, void*, void*) =0;
};
#endif /* !nsPLE_h */


regards,
