I'm trying to persist an entity via a simple jsp form but it doesn't work. the exception that appear is : javax.naming.NamingException: Lookup failed for 'java:global/jee-projet-web'.
I'm using glasfish as server.
This is the code of my form:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

I'm sure all the 3 last files are well placed. and now when running my program here is the error in the console:

Thank you for your coming help.

In AddAdmin servlet you have declared
private AdminManager adminManager;
as instance variable. And in init() method you are declaring local variable again with same name that's creating problem
Change
AdminManager adminManager = (AdminManager)context.lookup("java:global/jee-projet-web");
To
adminManager = (AdminManager)context.lookup("java:global/jee-projet-web");
Now, this line assigns the value to adminManager
Root cause is
java.lang.NullPointerException
at servlet.add.AddAdmin.doPost(AddAdmin.java:55)
I guess line number 55 is
adminManager.addAdmin(a); //variable adminManager is not initialized
adminManager is null so, calling any method on null throws NPE
Root exception is javax.naming.NameNotFoundException: jee-projet-web not found
This exception is thrown when a component of the name cannot be resolved because it is not bound.
Please ensure that the name jee-projet-web is already bound.
I guess it is typo mistake missing c in jee-projet-web. It should be jee-project-web.
