You need: <jsp:useBean id="transaction" class = "com.complusdata.beans.Transaction" scope="session" /> <jsp:setProperty name="transaction" property="email" value="<%=formHandler.getEmail()%>"/> .... Note the final '/>' on jsp:useBean. The way that you had it originally, the properties will only be set if the JSP page needs to create a new instance of "transaction". If it finds one in the session already, the setters are skipped. > > For Question #2 - that's exactly what I needed to know!! > > For Question #3 - hopefully I can get the session scope to work, but then > how would I program that button?
