Is it possible to send a List with jsp?

Question

Java

There is an object of type Resource. Its fields are: id, title, List, Date, Status. The Author object has its own fields, which we also output to jsp. How to display everything on jsp is clear, the question is how, when sending a POST request to a servlet, collect the List back and send it as a sheet. Is it possible? Preferably without Spring.

Answer 1

JSON

Answer 2

For example, there is a form

<form ...>
  <input name="lastName" value="Ivanov" />
  <input name="firstName" value="Ivan" />

  <input name="lastName" value="Petrov" />
  <input name="firstName" value="Petr" />
</form>

In a servlet, a request from such a form without frameworks can be processed like this

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

  // тут будит lastNames = {"Ivanov", "Petrov"}
  String[] lastNames = request.getParameterValues("lastName");

  // тут будит firstNames = {"Ivan", "Petr"}
  String[] firstNames = request.getParameterValues("firstName");

  List<Author> author = new ArrayList<Author>();

  for (int i = 0; i < lastNames.length && i < firstNames.length; i ++)  {
  
    author.add(new Author(firstNames[i], lastNames[i]));
  }
}

something like this...
