<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form name="TrainerMenu" action="TrainerMenu" method="get">

<h1>Benvenuto in LESSON! Scegli l'operazione da effettuare:</h1>
<input type="button" value="Creazione Nuovo Corso" name="CreateCourse" />
<input type="button" value="Gestione Autorizzazioni"
name="AuthorizationManager" />

</form>
</body>
</html>

Answer

You have several options, I'll start from the easiest:

1- Change the input buttons to links, you can style them with css so they look like buttons:

<a href="CreateCourse.jsp">Creazione Nuovo Corso</a>

instead of

<input type="button" value="Creazione Nuovo Corso" name="CreateCourse" />

2- Use javascript to change the action of the form depending on the button you click:

<input type="button" value="Creazione Nuovo Corso" name="CreateCourse" 
onclick="document.forms[0].action = 'CreateCourse.jsp'; return true;" />

3- Use a servlet or JSP to handle the request and redirect or forward to the appropriate JSP page.
