Bom dia.
Estou tendo problemas com a implementação do JSTL no meu projeto que, mesmo com as indicações de diversos tópicos no fórum sobre versões que devem ser usadas ( JSTL 1.2 , TomCat 9.0 ) não estou conseguindo prosseguir no curso. De certa forma, os únicos problemas de execução do TomCat são relacionados de alguma forma com o Servlet que faz o Request para o JSP e, consequentemente, o JSP que utilizaria do JSTL. Abaixo, seguem algumas informações referente ao projeto e, desde já, agradeço qualquer ajuda!
OBS: Estou usando o IntelliJ IDEA.
Servlet para listar empresas junto com o Request Dispatcher para o JSP
public class CompaniesListServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException {
PrintWriter out = resp.getWriter();
DataBase dataBase = new DataBase();
out.println("<html><body>");
for (Company company : dataBase.getRegisteredCompanies()) {
out.println("<p>" + company + "</p>");
}
out.println("</body></html>");
RequestDispatcher rd = req.getRequestDispatcher("listCom.jsp");
req.setAttribute("listCom", dataBase.getRegisteredCompanies());
rd.forward(req, resp);
}
}
JSP para a listagem dos objetos do Request
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Companies in system</title>
</head>
<body>
<ul>
<c:forEach items="${listCom}" var="company">
<li>
${company.name}
</li>
</c:forEach>
</ul>
</body>
</html>
