If you are using Spring MVC then you put the data in model object and as mentioned by fvu, access the model using JSTL tags, that is the best practise. Google it, you will get many examples – Chaitanya Mar 13 '17 at 10:42

@jithin, yes JSTL and Spring form tags is the right way to use it. – Chaitanya Mar 13 '17 at 10:44

@Chaitanya while using jstl to display an object in jsp do we need to specify the class name or something in the JSP page ? – jithin Mar 13 '17 at 10:48

@jithin, No not required to specify the class in JSP. Follow the answer given by Pascal, you will understand. – Chaitanya Mar 13 '17 at 11:02

Please see @BalusC's excellent answer on the subject:

Basically, accessing POJOs is discouraged because it leads to unmaintainable code. It is much better to use JSTL and Expression Language (EL).
To do that, here's his example:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
...
<table>
<c:forEach items="${products}" var="product">
<tr>
<td>${product.name}</td>
<td>${product.description}</td>
<td>${product.price}</td>
</tr>
</c:forEach>
</table>
