Hello, my friends. In this video, we'll create a project with Servlet Context and Listeners. Let's start. First, I want to hold person in a list and I want to show all persons in another page. First, let's define a new class as name, Employee. Let's define properties. Name, surname, job, and, age. Generate getters and setters. Now, turn back Servlet in do-post method. I want to hold values in a list. First, define an employee list. Now, we need an instance from employee. Now, set values to the employee. Now, add employee to the employee list. Now, if we try this we cannot see the result is true. Let's show results in console. Now, in do get method I want to add an empty employee list to the ServletContext. First, define ServletContext with getServletContext() and we will set list to context. Done, try. Add, add another one. Let's look at the console. As you can see, there are 2, 1 size. Why? Because we didn't use any listener. 

We need a listener to change ServletContext value. Let's add a listener. New listener, give a name as ContextListener. Next, now select lifecycle of contact servlet. Done, now, we have a listener. Let's adjust for ServletContext. First, get ServletContext value to a new context. Now, get list from context. If list equals null, set a new list to the context. Now, let's turn back Servlet. Now, in this page, we have to change this list creation. We already have a listener so we must create a list from context. Let's try again. Add two employees. Now, let's look at the result. As you can see, we have two employees in Servlet Context. Let's show employees in another page or let's show in first page. First ,we have to get list from Servlet, getServletContext(). Now, we will add a new append, employee names, their name, age, and job. Now, let's use a loop. Done, let's add another button to the JSP. We will redirect page to the first servlet. Let's try, add three employees, go to the other page. As you can see, we have three employees. Now, we have finished this video. In the next video, we will start using AJX. See you in the next video.
