Is Test a servlet class? or just a simple class?
Servlet solution (so you need the session in a doGet or doPost or doX method:

HttpServletRequest httpRequest = (HttpServletRequest) request;    //the request variable should be part of your method input variables. 

HttpSession session = httpRequest.getSession();

In other classes, where you don't have such a request variable, you can try:

FacesContext facesContext = FacesContext.getCurrentInstance();

HttpSession session = (HttpSession) facesContext.getExternalContext().getSession(false);   //false in the end, or you create a new session
