Erros Http redirecionados para um Controller. Como fazer?

Assuntos Gerais
#1

Gostaria de saber como é possível redirecionar erros http para um Controller do meu sistema.

Já ví muitas perguntas dessa no forum, mas no final as pessoas acabavam indo para páginas estáticas ou então só conseguiam redirecionar o erro 404.

Preciso executar códigos nos erros 403, 404 e 500

Controller

@Resource
@Path("/error/")
public class HttpErrorController {
	private final Result result;

	/**
	 * @param result
	 */
	public HttpErrorController(Result result) {
		this.result = result;
	}

	@Path("page-not-found")
	public void pagenotfound() {
		//código aqui
	}

    // outros erros

}

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

	<error-page>

		<location>/error/page-not-found</location>
	</error-page>

	<filter>
		<filter-name>vraptor</filter-name>
		<filter-class>br.com.caelum.vraptor.VRaptor</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>vraptor</filter-name>
		<url-pattern>/*</url-pattern>
		<dispatcher>FORWARD</dispatcher>
		<dispatcher>REQUEST</dispatcher>
	</filter-mapping>
</web-app>

esse do 404 funcionou? se sim, funciona da mesma maneira pro erro 500 ou 403

#3

Não funcionou não.

Só funciona se eu colocar a página de erro no webcontent. Sem controller.

#4

tenta mudar a declaração do vraptor pra:

<filter-mapping>  
        <filter-name>vraptor</filter-name>  
        <url-pattern>/*</url-pattern>  
        <dispatcher>FORWARD</dispatcher>  
        <dispatcher>REQUEST</dispatcher>  
        <dispatcher>ERROR</dispatcher>  
    </filter-mapping>

senão o erro não passa pelo vraptor

#5

Sabe se tem como pegar esses erros via um Interceptor?

#6

Olha a exceção que acontece se eu colocar o vraptor com o error dispatcher.

#7

estranho… dá erro dentro do tomcat… chega a executar seu controller?

#8

Não. Dá essa exceção e aparece a página 404 do tomcat. Acho que é do tomcat.

#9

problema é que cai aqui:

br.com.caelum.vraptor.resource.DefaultResourceNotFoundHandler.couldntFind(DefaultResourceNotFoundHandler.java:41)

que é chamado quando nenhum controller registrado trata a url… tem certeza que tá caindo na url certa? o caminho colocado na error page é o mesmo que tá no controller?

Vou tentar colocar /inwebpartners/error/page-not-found para ver se é isso, sei lá.

Será que está indo para o localhost:8081/error/page-not-found ?

#11

geralmente a url é a partir do contexto já
