Default EJB problem

hi
I am new to EJBs. I am developing a J2EE application using NetBeans IDE. My project is deployed successfully, but when I try to run the servlet from the webmodule to retrieve data from the database, I get the error "javax.naming.NamingException: ejb-ref: ejb/CustomerFacadeBean, no ejb-link in web.xml and no jndi-name in jboss-web.xml"

and the output is "No such Entity!"
These are my web.xml and jboss-web.xml files

web.xml:
<?xml version="1.0" encoding="UTF-8"?>
