Hello,
What do you mean by "handle?"
Basic functionality is....
You can obtain the current HttpSession object from the request object through:
HttpSession session = request.getSession(true);
specifying "true" will create a new session if one does not already exist.
You can put stuff into and get stuff out of your session thusly:
session.setAttribute("key", value);
session.getAttribute("key");
The key in the set method has to be a String, but the value can be any object.
Thus you can get your session and its attributes anyplace you can access the request object. (mostly on a JSP or in a Servlet).

It is sorta covered in the JavaRanch Style Guide.
