Re: about xpcommexception

You need to initialize JavaXPCOM:
	Mozilla.getInstance().initialize(grePath);

and you need to initialize Mozilla:
	Mozilla.getIntance().initEmbedding(grePath, grePath, locationProvider);

You need to provide the 'locationProvider' class.  Have a look at the 
embedding documentation on http://developer.mozilla.org.
