Session attribute access and converting to int?

Question

I have stored user id in Session using following command in Servlet:

HttpSession session = request.getSession();
session.setAttribute("user", user.getId());

Now, I want to access that user id from another Servlet:

HttpSession session = request.getSession(false);
int userid = (int) session.getAttribute("user"); // This is not working

OR

User user = new User();
user.setId(session.getAttribute("user")); This ain't possible (Object != int)

Question:

1. How can I cast to int and send the id to DAO for SELECT statement

Answer 1

I'm not good at JAVA but I used to do it like
Integer.parseInt(session.getAttribute("user").toString())

Try once, but just be sure to check null for session.getAttribute("user") before calling toString
