I'm not sure what your web controller might be.  You can inject an  
entity manager into a servlet or jsf managed bean using an  
@PersistenceContext annotation; the related annotations for EMF or  
getting an EM into jndi also work the same as for ejbs.  You can't  
get an EM injected into a non-managed object that you create  
yourself, for such an object you would have to look it up in jndi
