Olá pessoal estou com um problema estranho aqui …

Tenho uma aplicação básica aqui em que comecei a sofrer com alguns NPE e fui ver o motivo e vi que está havendo duplicidade de chamada no recurso mesmo eu pedido 1 vez só…
ta meio estranho isso nao tem motivo pra ser chamado duas vezes …

por exemplo se eu chamo a url http://localhost:8081/projeto/logpanel/list

ele imprime um sysout que coloquei em um interceptor que o accepts é sempre true

Requested url =>http://localhost:8081/smartoffice/logpanel/list
Requested url =>http://localhost:8081/smartoffice/logpanel/list

está passando duas vezes pelo mesmo interceptor , o que pode estar errado ??

em todo caso vou postar o interceptor

@Intercepts
public class ErrorInterceptor implements Interceptor {
	private Result result;
	private HttpServletRequest request;
	private EmailPanelDao daoEmailPanel;
	private LogPanelDao daoLogPanel;
	private ConfiguracaoDao daoConfiguracao;
	private static Logger logger = Logger.getLogger(ErrorInterceptor.class);

	public ErrorInterceptor(Result result, HttpServletRequest request,
			LogPanelDao daoLogPanel, ConfiguracaoDao daoConfiguracao,
			EmailPanelDao daoEmailPanel) {
		this.request = request;
		this.result = result;
		this.daoEmailPanel = daoEmailPanel;
		this.daoLogPanel = daoLogPanel;
		this.daoConfiguracao = daoConfiguracao;
	}

	public boolean accepts(ResourceMethod method) {
		return true;
	}

	@SuppressWarnings("unchecked")
	public void intercept(InterceptorStack stack, ResourceMethod method,
			Object resourceInstance) {
		
		System.out.println("Requested url =>" + request.getRequestURL());
		
		try {
			stack.next(method, resourceInstance);
		} catch (InterceptionException i) {
			if (i.getMessage().contains("ClientAbortException"))
				logger.warn("ClientAbortException => "
						+ request.getRequestURL() + " => " + i.getMessage());
			else {
				PrintWriter p = null;
				try {
					StringWriter w = new StringWriter();
					p = new PrintWriter(w);
					i.printStackTrace(p);
					String requestedUrl = request.getRequestURL().toString();
					String exception = w.toString();
					StringBuilder params = new StringBuilder("{");
					Enumeration<String> en = request.getParameterNames();
					while (en.hasMoreElements()) {
						String paramName = en.nextElement();
						params.append("<br/> " + paramName + " : "
								+ request.getParameter(paramName) + ",");
					}
					params.append("}");

					daoLogPanel.saveLog(exception, requestedUrl,
							params.toString());

					daoEmailPanel.sendMail(daoConfiguracao.getVariableValue(
							"SYSTEM", "EMAIL_SUPPORT"),
							"ERRO EXECUÇÃO", "URL : "
									+ requestedUrl + "<hr/>" + exception
									+ "<hr/>" + params);

				} catch (Exception e1) {
					e1.printStackTrace();
				} finally {
					if (p != null)
						p.close();
				}
				result.use(Results.logic()).redirectTo(GeneralController.class)
						.error();
			}

		}
	}

O fato dele imprimir o log duas vezes pode ser que seu logger esteja declarando o appender duas vezes. Coloca um sysout para ver se passa duas vezes, ou até um breakpoint.

Outra coisa que você pode verificar é se o filter do VRaptor está sendo declarado duas vezes no web.xml. Também pode acontecer de você estar em um container com Servlet 3, que já registra o filter, e você declara-o novamente no web.xml.

Garcia já é um sysout está passando duas vezes mesmo…

public void intercept(InterceptorStack stack, ResourceMethod method,  
            Object resourceInstance) {  
          
        System.out.println("Requested url =>" + request.getRequestURL());  
        .
        .
        .
}

meu web.xml não tem chamada em duplicidade do filter

E o tomcat que uso é versao 6.0.29 que não implementa servlet 3 ainda … se nao me engano isso só implementado nas versões 7.x

Creio não estar fazendo nada de errado ? alguma ideia ??

o que tem dentro da lógica http://localhost:8081/smartoffice/logpanel/list?

pode ser só a parte do vraptor (que envolve o result)

Bom vamos lá…

@Resource
@Path("logpanel")
public class LogPanelController {

	private LogPanelDao daoLogPanel;

	private Result result;

	public LogPanelController(Result result, LogPanelDao daoLogPanel) {
		this.result = result;
		this.daoLogPanel = daoLogPanel;
	}

	@VerifyAccess

	}

	@VerifyAccess

o ErrorInterceptor é chamado uma única vez. O que acontece é que sua aplicação está fazendo duas requisições pra /logpanel/list, por algum motivo. Por isso tá imprimindo duas vezes.

pq vc quer ignorar /tagria/*? por causa das imagens, css e js?

o ErrorInterceptor é chamado uma única vez. O que acontece é que sua aplicação está fazendo duas requisições pra /logpanel/list, por algum motivo. Por isso tá imprimindo duas vezes.

pq vc quer ignorar /tagria/*? por causa das imagens, css e js?


sim quero ignorar pq ja tenho uma servlet que ja trata recursos desse tipo (imagens,css,js) …

é entendi o que voce diz que numa request ele so chama uma vez…ate ai tudo ok…mas eu num entendo pq esta chamando duas vezes sendo que só é feita uma requisição…
não tenho nada de extraordinario na aplicação…e nem vejo por onde começar … tem alguma dica ?

as imagens, css e js vão passar pelo vraptor, mas ele vai passar pra frente diretamente. A primeira coisa que ele faz é verificar se existe um arquivo que responde pela URL passada, não tem problema deixar o VRaptor filtar essas requisições também.

talvez exista algo no html gerado.
Dê uma olhada se não existe alguma coisa do tipo:

<img src="" .../>
<link href="" .../>
<script src="" ...>

ou também se estiver src=".". Assim toda vez que vc chamar a página ele vai fazer outro request pra ela mesma.

Mesmo arriscando a fúria da galera por ressucitar uma thread tão antiga…

Tive exatamente o mesmo problema. Inexplicavelmente “do dia para a noite” o VRaptor começou a chamar 2x todos os métodos dos controllers. Começou com apenas 1 método, depois foram todos.

Eu tinha algo como:

@Path("/api/entidade/acao/?")
public void acao() {
  // busca coisas no BD
  result.use(Results.representation()).from(resultado).serialize(); // Uso o plugin do vraptor para Gson ;P
}

E sempre acabava em um erro 500 devido a Session do Hibernate estar fechada. Fui investigar e acabei vendo via debug (detesto debug!) que o método estava sendo executado 2x “magicamente” (nem sequer estava na execution stack… simplesmente pulava do nada para dentro do método novamente…)

Depois de muita, muita, MUITA briga, confusão, testes… acabei descobrindo o verdadeiro culpado: O WORK DO TOMCAT!!

Apaguei a pasta /work do Tomcat e tudo voltou a funcionar mágicamente.

-1 Ponto para o Tomcat ;(
