Problemas com meu arquivo XML de configuração do VRaptor

Front-end
#1

Olá pessoal,

estava eu aprendendo a usar alguns frameworks web e me deparei com um problema ao tentar configurar o XML do VRaptor. Veja o que acontece no seguinte código:

<?xml version="1.0" encoding="ISO-8859-1"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"> <servlet> <servlet-name>vraptor2</servlet-name> <servlet-class>org.vraptor.VRaptorServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>vraptor2</servlet-name> <url-pattern>*.logic</url-pattern> </servlet-mapping> </web-app>

na linha 1 aparece: No grammar constraints (DTD or XML schema) detected for the document.
e na linha 2 aparece: cvc-elt.1: Cannot find the declaration of element ‘web-app’.

Bom, ao meu ver esta tudo correto, pois tenho instalado o plugin Amateras e o GEF-ALL(necessário para o Amateras).

a mensagem de erro do tomcat é a seguinte:

[code]description The server encountered an internal error () that prevented it from fulfilling this request.

Alguem sabe o que pode estar errado ai? O que impede meu formulario de ser executado?

OBS: o DaoInteceptor está correto.

Cara, não precisa usar o amateras, usa só o eclipse WTP que já é suficiente.
O erro no xml é que está faltando o DTD ou xml schema, para voce resolver isso inclua deixe seu header parecido com esse daqui:

<web-app version="2.4"
	xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

Note que no seu xml estão faltando os atributos xmlns:xsi e o xsi:schemaLocation.

Bem, agora sobre o Vraptor, me responda a uma questão…

O seu DaoInterceptor está com modificador de classe public?

Abraço

O problema estava em meu xml mesmo, obrigado pela ajuda.

Quando ao resto esta tudo correto, obrigado mais uma vez.
