Using useBean for authentication

Question

Hi,
I am creating a login page for personalization, After the login the user can access his/her information, so in my authentication.jsp I am making all the properties available to the user. However I have the properties stored in two different beans, so I am using two useBean statements for each bean and for each of the beans properties. So when I try to compile the page I get the following error:
jsp.error.useBean.duplicate
Is it not allowed to use two <jsp:useBean> in the same jsp page?
I have two databases user and education.
snips of my code:
<sql:query var="dbInfo">
Select * from user, education where user_id= ? AND password =? AND user.user_id = education.userid
<sql:param value="${param.userid}" />
<sql:param value="${param.password}" />
</sql:query>
<c:set var="EducationDb" value="{dbInfo.rows[0]}" />
<jsp:useBean id="validUser" class="EducationBean" scope="session" >
<c:set target="${validUser}" property="userid" value="${EducationDb.userid}"
<!-- same for the rest of the properties in the bean and database columns -->
<c:set var="UserDb" value="${dbInfo.rows[0]}" />
<jsp:useBean id="validUser" class="UserBean" scope="session">
<c:set target="${validUser}" property="name" value="${UserDb.name}"/>
<!-- same for all the other properties in the bean and database columns -->
Thanks
