how can i get the session attribute in desired type

Question

from another java application, i had already set my attribute to this:

     HttpSession session = request.getSession(true);
     session.setAttribute("SessionUser", userName);

I'm not sure how to parse a specific attribute into a string.

String query = "SELECT title, first, last, email FROM member WHERE email="+**??**;

Answer 1

String username = (String) session.getAttribute("SessionUser");

Answer 2

You seem to be only adding the user's name into the session attribute.

Try setting the entire User object (whatever is the domain object in your case) as follows:

session.setAttribute("SessionUser", userObj);

Then fetch the object using:

UserObj userObj = (UserObj) session.getAttribute("SessionUser");

and then use it in your query, something like this: (assuming you have a getEmail() in the UserObj)

String userEmail = userObj.getEmail();
String query = "SELECT title, first, last, email FROM member WHERE email="+ userEmail;

Answer 3

if userName attribute is a String object, then you can call it with

String userName= (String)session.getAttribute("SessionUser");
String query = "SELECT title, first, last, email FROM member WHERE email="+ userName;

or it's bean? then;

UserBean user = (UserBean)session.getAttribute("SessionUser");
String query = "SELECT title, first, last, email FROM member WHERE email="+ user.getUserName();
