No passo 6 (Serviço com XML) da aula 06, o meu navegador apresenta erro HTTP 500. Meu código está assim:
XStream xstream = new XStream();
xstream.alias("empresa", Empresa.class);
String xml = xstream.toXML(empresas);
response.setContentType("application/xml");
response.getWriter().print(xml);O erro aparece assim:
