The Servlet container currently does not give you direct access to any NoServer functionality. You can finesse it by backing or fronting with a NoServer app.
Our Servlet container is a very lightweight 2.5 container that has JSP and JNDI support and you interface with the persistence natively (i.e., JDBC).
We will be releasing build pack support for PaaS apps very soon that will allow you to choose the stack (i.e., Jetty, Node. Thin, etc.) and services (i.e., Postgres, Mysql, Cassandra, etc.) you want.
NoServer has some very power features that would be very interesting in a PaaS context and I need to discuss this with Gary (the NoServer creator) to see what's doable.
Hope this helps.
