Don't get hanged up on this servlet question. Just because it's a servlet
doesn't change Java rules. Of course you can instantiate a class in a servlet.
You don't have to import if it's in the same/none package and is in the
classpath

// assuming that Lecturer is a class in a classpath of your servlet engine;
// not necessarily in the servlets directory
public void doGet(HttpServletRequest request,
HttpServletResponse response
)throws ServletException, IOException
{
HttpSession session = request.getSession();
// create new lecturer
Lecturer lect = new Lecturer()
// put it in session context for future use when you come back
// with another request (or for use in JSP)
session.putValue("Lecturer",lect);
sContext.getRequestDispatcher("/LecturerPage.jsp").forward(request,response);
