These interfaces will have your application specific business methods. Have a look at http://trailblazer.demo.jboss.com/EJB3Trail/[/url], which provides examples of EJB3 and other stuff. Specifically for a Simple Stateless Bean have a look at [url]http://trailblazer.demo.jboss.com/EJB3Trail/serviceobjects/slsb/index... As far as the NameNotFoundException is concerned, you are using the incorrect JNDI name for looking up the bean. Once you have read through the above mentioned links and successfully deployed the bean, the client can lookup the bean using the JNDI name syntax mentioned in the Session Bean Client section in the second link above.
