[news.eclipse.technology.equinox] How to read file of the bundle in serv

[jeffidea@xxxxxxxxxx (Jeff)]

I deploy my web-bundle in server-side equinox, but how can I read file in 
my bundle? for example, my bundle file structure:
|-conf
|   |-sys.xml
|-lib
|-src
How can I read sys.xml? Must I need to use org.eclipse.core.resources 
bundle?
