Question

Which method is used to store an object in the session?

Please give me answer from given options.

1. setValue
2. putObject
3. setSession
4. setAttribute

Answer 1

You can use setAttribute method to store an object in the session

HttpSession session = request.getSession();
Object obj = new Object();
session.setAttribute("object", obj);

and after setting your attribute by using session, use following to access it in the JSP,

${sessionScope.object}

or

<%= session.getAttribute("object")%>

Answer 2

The solution is to use: javax.servlet.HttpSession.setAttribute()

HttpSession session = request.getSession(); 
session.setAttribute("sessionparam", paramValue)
