Question

I’m trying to get started with session-scoped beans in Spring Web MVC 3. I put this line in my dispatcher configuration:

<bean id="userInfo" class="net.sandbox.sessionbeans.UserInfo" scope="session" />

Here is net.sandbox.sessionbeans.UserInfo:

package net.sandbox.sessionbeans;

public class UserInfo {
    public String username;

    public UserInfo() {
        this.username = "Unregistered User";
    }
}

How can I access session-scoped beans inside the JSP files that represent the View part of my application? I tried this…

<p align="right">${userInfo.username}</p>

… but that didn’t give me the expected result, i.e.

<p align="right">Unregistered User</p>

Instead I just get

<p align="right"></p>

What am I doing wrong?

This answer is partially based on some advice that was posted in the question’s comments but was later deleted by the poster. I added this to every JSP page that needs to use the bean:

<jsp:useBean id="userInfo" scope="session" class="net.sandbox.sessionbeans.UserInfo" />

I then found this article detailing how you can use beans in a JSP page.
