Basic useBean question

I put this at the top of my JSP
<jsp:useBean id="userInfo" scope="session" type="hause.user_management.User"/>
Now I get the following error:
javax.servlet.ServletException: bean userInfo not found within scope
What causes this error? (This is the first time I've tried to use the useBean tag in my jsps.)

Replace the type attribute with the class attribute as
<jsp:useBean id="userInfo" scope="session" class="hause.user_management.User"/>
The class attribute instructs the JSP engine to create a new instance of the specified class if an existing one is not found.
For a detailed explanation on the different attributes of the useBean tag, have a look at this chapter.
