How to retrieve from session object in JSP?

Question

I have a User Object which contains details like Name, Contact Details etc & I am storing this object in a session attribute. How do I save the name and contact details in a String variable in JSP Scriplet?

I tried using

String uname1 = (String) request.getSession().getAttribute(${requestScope['users'].getName()});

and many other combinations But it fails

My JAVA code

user = userDetails.getByUsername(username);

request.getSession().setAttribute("uname", user);

and in JSP I have

<%

String uname = (String) request.getSession().getAttribute("uname");
if (uname != null) {
response.sendRedirect("home.jsp");
}

%>

How Do I extract "name" from "uname" object and store it into a variable to be used for checking null value ?

Answer 1

you could store only the name in the session instead of the User object

user = userDetails.getByUsername(username);

request.getSession().setAttribute("uname", user.getName());

because i see that in the jsp you are expecting a String object, if you want to store a User object than you should expect a User object instead of a string in the jsp

user = userDetails.getByUsername(username);

request.getSession().setAttribute("uname", user);

<%

User user = (User) request.getSession().getAttribute("uname");
if (user.getName() != null) {
response.sendRedirect("home.jsp");
}

%>
