If what you mean to do is to have a client submit a form, and then if you need to display it again, populate it with the data sent by the client, then you can do it with a combination of JSP-JavaBeans.
Create a JavaBean with instance member names matching the input element names in the form. When the user submits the form, use <jsp:setProperty> tag to store all the data submitted in the JavaBean. If you need to display the form again, use that bean to populate it with the values sent by client earlier.
