I'm having trouble writing an empty field because it's being formatted with SimpleDateFormatt ..

Writing the console generates an error

    java.text.ParseException: Unparseable date: ""

Servlet

    private void gravarProximo(HttpServletRequest request, HttpServletResponse response) {
    try {
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm");
        SimpleDateFormat sdf2 = new SimpleDateFormat("dd/MM/yyyy HH:mm");


        OrdemServico c = (OrdemServico) request.getSession().getAttribute("ordemServico"); 

                c.setDataOpen(sdf.parse(request.getParameter("dataOpen")));
                c.setDataClosed(sdf2.parse(request.getParameter("dataClosed")));

Can anyone help me with how to make it write even if the field is empty?

In the database there is no null ...

jsp servlet

Your problem is not time saved in the bank.

The exception java.text.ParseException: Unparseable date: "" refers to the parse you try to make of an empty%%.

It is very simple to solve this, just check first if the string is empty:

private void gravarProximo(HttpServletRequest request, HttpServletResponse response) {
  try {
      SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm");
      SimpleDateFormat sdf2 = new SimpleDateFormat("dd/MM/yyyy HH:mm");
      OrdemServico c = (OrdemServico) request.getSession().getAttribute("ordemServico"); 

      String dataOpen = request.getParameter("dataOpen");
      if(dataOpen != null && !dataOpen.isEmpty()){
           c.setDataOpen(sdf.parse(dataOpen));
      }
      String dataClosed = request.getParameter("dataClosed");
      if(dataClosed != null && dataClosed.isEmpty()){
           c.setDataClosed(sdf2.parse(dataClosed));
      }

You can now save your ServiceObject object normally.
