Olá pessoal. Estou iniciando meus estudos com VRaptor 3 e me deparei com um problema. Ao testar algumas possibilidades de envio de valores para a view, o mesmo não teve sucesso ao enviar valores primitivos (int, long, float, double…). Quando tentava acessar a view, estourava uma exception. Fiz alguns testes e conclui que o problema é o Tomcat 7, pois em versões anteriores do Tomcat a execução obteve total sucesso. Minha dúvida é a seguinte: a EL 2.2 existente no Tomcat 7 não permite a realização do parse de primitivos na view?
Só para constar, vou postar minha classe e o trecho do jsp:
package br.com.caelum.goodbuy;
import br.com.caelum.vraptor.Resource;
@Resource
public class FirstResource {
public int valor() {
return 100;
}
public String ola() {
return "Ola Mundo";
}
}A impressão do valor no jsp:
<body>
O valor existente no resource é: ${int }
</body>E aqui segue a stacktrace:
