Java EE (Java Enterprise Edition) General Discussion

I have the following code:

<%@ page import="java.util.*" %>
<jsp:useBean id="EducationBean" class="java.util.Hashtable" scope="session" />

<%
String swCurrFileName = "swcontrol.jsp";
Enumeration params = request.getParameterNames();
while (params.hasMoreElements()) {
String name = (String)params.nextElement();
EducationBean.put(name, request.getParameter(name));
}
%>

My question is I can't find any documentation on the put command, whats the difference between 'put', and 'putValue', and 'setAttribute'? When I try using the 'putValue' or 'setAttribute' command I get errors.

What I'm trying to do is store form values in a session object across several pages, and on the last page display all the form values from the previous pages.
