To my mind EJB's should never be accessed directly from JSP or serlvet. If
you want to build something thats scalable and channel independent then JSP
should handle only basic presentation layer stuff, anything else - EJB's,
business logic etc should be handled elsewhere.
IMHO JSP should just call getters and setters on a class (or bean) that sits
behind the JSP. That bean or class should then invoke other classes or
EJB's as required.
