Add values to arraylist use JSTL

Question

is it possible to add values to an ArrayList instead of using a HashMap

something like:

Answer 1

JSTL is not designed to do this kind of stuff. This really belongs in the business logic which is (in)directly to be controlled by a servlet class.

Create a servlet which does like:

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    List animals = new ArrayList();
    animals.add("Sylvester");
    animals.add("Goofy");
    animals.add("Mickey");
    request.setAttribute("animals", animals);
    request.getRequestDispatcher("/WEB-INF/animals.jsp").forward(request, response);
}

Map this on an url-pattern of /animals.

Now create a JSP file in /WEB-INF/animals.jsp (place it in WEB-INF to prevent direct access):

    ${animal}

No need for jsp:useBean as servlet has already set it.

Now call the servlet+JSP by http://example.com/context/animals.
