Problemas com meu arquivo XML de configuração do VRaptor

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:

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:

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:

Note que no seu xml estão faltando os atributos xmlns

si 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.
