There's an easy way if you don't need hibernate to be working behind the scene (e.g, replacing TopLink as the JPA implementation).
Basically, you just need to initialize hibernate SessionFactory once on startup, and put it somewhere accessible from your business logic code.
On servlet container, usually you would want to attach a ContextLoaderListener and initialize hibernate there and put it in ServletContext. You can then get sessionFactory from your servlets using httpServletRequest.getSession().getServletContext().
Same idea for ejb. I'm not sure how to accomplish that though. Maybe instantiating the sessionFactory in a startup listener and register it on JNDI. I'm not sure, still learning all these EJB stuff.
