My Object Array is this: [Color [id = 1, CodeColor = Red], Color [id = 2, CodeColor = Green]] and this is my jquery code to go through that array and paint it in an option: function Color (id, codeColor) { this.id = id, this.coDigoColor = codeColor }

        function mostrarColores(){
            $.each(colores, function(color){

                let html = '<option>${color.id}</option>';

                $("#ejemploColor").append(html);
            }); 
        }

        mostrarColores();

When I execute it, it says the following: Can not use 'in' operator to search for 'length' in [Color [id = 1, codeColor = Red], Color [id = 2, CodeColor = Green]]

I recommend that in your controller or servlet in java you establish a list like the following

ArrayList miLista = new ArrayList();
...
request.setAttribute("miLista", miLista);

and already after that in your jsp you run it this way with a foreach, without using JQuery

<select name="database1">
  <c:forEach items="${lista}" var="miLista">
    <option value="${lista}">
        ${lista}
    </option>
  </c:forEach>
</select>

Greetings
