Hi,
I am just learning Java EE, I have created a Persistence entity for a User object, which is stored in the database. I am now trying to create a JSP page that will allow a client to enter a new User object into the System. I am unsure of how the JSP page interacts with the User facade, the tutorials are confusing me a little.
This is the code for the facade:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Add User to System</title>
</head>
<body>
<h2>Add User</h2>
<h3>Please fill out the details to add a user to the system</h3>
<form action="">
<label>Email:</label>
<input type="text" name="email"><br />
<label>Password:</label>
<input type="password" name="name"><br />
<label>Name:</label>
<input type="text" name="name"><br />
<label>Address:</label>
<input type="text" name="address"><br />
<label>Type:</label>
<select name="type">
<option>Administrator</option>
<option>Member</option>
</select><br />
<input type="submit" value="Add" name="add"/>
<input type="reset" value="clear" />
</form>
</body>
This is the code I have to add a new User object within the User facade class:
@Stateless
public class CinemaUserFacade {
@PersistenceContext(unitName = "MonashCinema-warPU")
private EntityManager em;
public void create(CinemaUser cinemaUser) {
em.persist(cinemaUser);
}
I am finding it a little difficult to get my head around the whole MVC thing, getting there but would appreciate it if someone could turn the light on for me!
