How to add a new XPCOM service baked into LibXUL?

Hi all,

I'm trying to create a new XPCOM service that must be accessible from
within LibXUL (specifically, from within the gfx module). So I'm
basically creating something as "low level" as "@mozilla.org/docshell;
1".

I'm using the config below, which doesn't seem to be working: My tree
compiles fine with the service is not visible from xpcshell when I
referenced it with contract ID (the interface is visible). (Yes, my
service is marked `scriptable`)

1. I am using this directory structure:

    gfx/my_xpcom/Makefile.in    (Just DIRS `public` and `src`)
    gfx/my_xpcom/public/Makefile.in
    gfx/my_xpcom/public/myService.idl
    gfx/my_xpcom/src/Makefile.in    (This file is attached below)
    gfx/my_xpcom/src/MyService.h
    gfx/my_xpcom/src/MyService.cpp
    gfx/my_xpcom/src/MyServiceFactory.cpp    (Mostly copied from xpcom/
sample)

2. I'm using these options for `src/Makefile.in`. These are mostly
written from intuitions and looking around other Makefile.in (Full
file is attached at the end)

    MODULE         = my_service
    LIBRARY_NAME   = my_service
    MODULE_NAME    = my_service
    EXPORT_LIBRARY = 1
    GRE_MODULE	= 1
    LIBXUL_LIBRARY = 1
    IS_COMPONENT	= 1
    FORCE_STATIC_LIB = 1

3. I also included `my_service` as a `COMPONENT_LIBS` in `toolkit/
library/libxul-config.mk`

Any help would be greatly appreciated!

Best regards,
Chris Yuen
