Answer 1

Try getting the object you set in ModelView by using request.getAttribute method. i.e

<% Documents document = (Documents)request.getAttribute("document"); %>

Now as you have document object available in your jsp page you can use it for retrieving any field, in your case 'pub_date'.

<% DateUtil.TimestampToSpecificString(document.pub_date) %>

Don't forget to import Documents class in your jsp page.
