UserManagement

accesses the

UserBean

entity by looking up

UserBean

 s home

interface as follows:

package com.rickhightower.auth;

import javax.naming.Context;

import javax.naming.InitialContext;

import javax.naming.NamingException;

public class UserManagementBean implements SessionBean {

private LocalUserHome getUserHome() throws NamingException {

Context initial = new InitialContext();

return (LocalUserHome) initial.lookup("java:comp/env/ejb/LocalUser");

}

Notice that the

getUserHome()

method is a private helper method that returns a

reference to the

UserBean

 s home interface (

LocalUserHome

). In order for the

UserManagementBean

to have access to the

UserBean

 s home interface the

following had to be added to the

UserManagementBean

 s deployment descriptor

within the session element as follows:

...

ejb/LocalUser

Entity

com.rickhightower.auth.LocalUserHome

com.rickhightower.auth.LocalUser

userEntity.jar#UserBean

...

Notice that the ejb local ref defines the reference to the

UserBean

. (The

UserBean

is

contained in an

.jar

file called

userEntity.jar

that I will cover in detail in

Compiling and

packaging your application

on page 31 .)
