My webapp is ready but I just wanted to add a little dropdown menu with the username as title. This is my jsp code:

                <i class="icon-user"></i> 
                <%
                    session.getAttribute("name");
                %>
                <span class="caret"></span>

and it sais

session cannot be resolved

9:              <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
10:                     <i class="icon-user"></i> 
11:                     <%
12:                         session.getAttribute("name");
13:                     %>
14:                     <span class="caret"></span>
15:                 </a>

There is a session because I’m logged in.

You can use EL, which is prefered in JSP.

<c:out value="${sessionScope.name}"/>

Or if the name value is HTML safe, you can use

${sessionScope.name}

Make sure the JSP is allow access session.

<%@ page session="true" %>

To use core JSTL, make sure the following code is included.

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
