vRaptor - br.com.caelum.vraptor.core.DefaultResult.use(DefaultResult:69)

Front-end
#1

Olá, boa tarde.

Estou iniciando os estudos no framework vRaptor e adquiri o e-book da Casa do Código sobre o mesmo.

Pois bem, seguindo com o sugerido no e-book, criei um novo Dynamic Web Project no eclipse, inclui todas as libs do vraptor-3.5.3-distribution.zip no WEB-INF/lib.

Copiei o web.xml do projeto pronto do e-book(livraria-projetos-criados.zip) e retirei os SiteMeshFilter.

Quando rodo o projeto e tento acessar algum método via navegador, há o erro:

Desde já agradeço.

vc chegou a criar algum controller?

Boa noite!

Sim, criei o LivrosController e o formulario.jsp, conforme e-book.

Segue meu web.xml

Só para checar:

o seu WEB-INF/lib tem os jars do spring, do guice e do pico, certo?

se sim, remova todos os jars do spring e do pico e tente de novo, por favor.

#5

Olá, boa noite.

Obrigado pela atenção.

Seguindo suas orientações, removi os jars do spring, guice e pico, contudo, há apenas o 404 no navegador e o erro abaixo no console.

Era pra deixar os do Guice =)

#7

Olá, Lucas.

Deixando os guice, continua o 404 e o erro no console é este.

Será que não é algo com relação ao Deployment Assembly ou o Build Path? Pois só copiei e colei os jars no WEB-INF/lib, nada mais.

Agradeço a atenção.

precisa do jar do javax.inject também.

Lucas, o erro no console ao acessar a página, agora, foi esse:

Mesmo erro que estava encontrando no início.

#10

se vc está com o jar jsp-api.jar ou standard.jar no WEB-INF/lib, tente removê-los

qual servidor vc está usando?

#11

Não há nenhum desses dois jars.

Tomcat 7.

#12

se vc subiu pelo eclipse, tenta dar um clean no projeto e no servidor…

isso tem cara de conflito de versão de classes…

verifique se vc tem tb o jar da jstl no WEB-INF/lib, se tiver, tire.

veja se vc está compilando o projeto na mesma versão do java que vc tá rodando o servidor.

LinkageError geralmente acontece por causa disso.

#13

Olá, Lucas.

Após todas as modificações solicitadas eu dei um clean no servidor.

A jstl não está no lib.

Estou usando a JDK 7 update 21.

#14

Não entendo o porque de não funcionar.

O Blank Project funciona perfeitamente.

Vou continuar seguindo o e-book e o utilizando como base.

Obrigado pela atenção.

#15

Da uma olhada aqui também tive o mesmo problema, e estou postando a solução aqui pra que mesmo muito tempo depois outras pessoas também há encontrem.

Quero agradecer pelo que foi explorado aqui neste tópico. Vendo a resposta e diante da mesma dificuldade com o vraptor-blank-project-3.5.3, coloquei as libs:

org.springframework.aop-3.0.0.RELEASE.jar org.springframework.asm-3.0.0.RELEASE.jar org.springframework.aspects-3.0.0.RELEASE.jar org.springframework.beans-3.0.0.RELEASE.jar org.springframework.context-3.0.0.RELEASE.jar org.springframework.core-3.0.0.RELEASE.jar org.springframework.expression-3.0.0.RELEASE.jar org.springframework.web-3.0.0.RELEASE.jar

Deu certo, funcionou.

Obrigado!
