Получается такая ошибка, берется null pointer exception
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.setContentType("text/html");
HttpSession session = req.getSession(true);
MessageDAO msg = new MessageOracleDAO();
User user = new User();
try {
if(session.getAttribute("authUser") != null) {
user.setEmail(session.getAttribute("authUser").toString());
session.setAttribute("User_messages", msg.inboxMessage(user));
}
} catch (SQLException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
req.getRequestDispatcher("mailbox.jsp").forward(req,resp);
}
