Java – change JSP button click

• Java

I have a question

I have three JSP pages The first is a menu with two buttons When I click the first button, I want to open the second JSP page When I click the second button, I want to open the third JSP page

Can you help me? I have to use a servlet (that's not a problem, I know)?

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
  "http://www.w3.org/TR/html4/loose.dtd">
<html>
<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>

Solution

You have several choices. I'll start with the simplest aspects:

1 - change the input button to a link, and you can style it with CSS to make it look like a button:

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

replace

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

2 - use JavaScript to change the operation of the form according to the button you click:

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

Use servlet or JSP to process the request and redirect or forward it to the corresponding JSP page
