I followed some tutorials to make the audio play automatically when certain conditions are met. However, the audio does not play automatically. Here is my code.
Parts_Request_Display_Servlet.java
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession();
User usr = session.getAttribute("currentSessionUser") != null ? (User) session.getAttribute("currentSessionUser") : new User();
if (!(UserBean.is_supervisor(usr) || UserBean.is_schedule(usr))) {
response.sendRedirect("/hdi.jsp?err=AccessDenied");
return;
}
ArrayList<Parts_Request_Display_Data> slist = new ArrayList<Parts_Request_Display_Data>();
NumberFormat nfi = NumberFormat.getInstance();
try {
slist = new Parts_Request_Display_Beans().GetRequestFormDisplayList();
} catch (SQLException e) {
e.printStackTrace();
}
