servlet and resource injection

With the latest version of Sun Application Server, it didn't appear to support resource injection in servlet (JDBC resources). Is this a version thing? Which version of servlet spec does it support?

Add more info, I was able to inject resource into web service modules, but those web services modules are servlet themselves though... am I correct?
