Senhores…

Estou migrando um projeto do vraptor para o mavem, e estou tendo alguns problemas…

Quando acesso um endereço mapeado pelo controller acontece o seguinte erro:

17:28:01,285 DEBUG [VRaptor ] VRaptor received a new request 17:28:01,333 DEBUG [DefaultRequestExecution] executing stack DefaultRequestExecution 17:28:01,382 DEBUG [ToInstantiateInterceptorHandler] Invoking interceptor ResourceLookupInterceptor 17:28:01,383 DEBUG [DefaultResourceTranslator] trying to access / 17:28:02,160 DEBUG [VRaptor ] VRaptor ended the request 17:28:04,505 DEBUG [VRaptor ] VRaptor received a new request 17:28:04,508 DEBUG [DefaultRequestExecution] executing stack DefaultRequestExecution 17:28:04,519 DEBUG [ToInstantiateInterceptorHandler] Invoking interceptor ResourceLookupInterceptor 17:28:04,519 DEBUG [DefaultResourceTranslator] trying to access /clientes 17:28:04,523 DEBUG [DefaultResourceTranslator] found resource [DefaultResourceMethod: ClientesController.listaClientesController.lista()] 17:28:04,530 DEBUG [ToInstantiateInterceptorHandler] Invoking interceptor FlashInterceptor 17:28:04,534 DEBUG [ToInstantiateInterceptorHandler] Invoking interceptor InterceptorListPriorToExecutionExtractor 17:28:05,587 DEBUG [InstantiatedInterceptorHandler] Invoking interceptor HibernateTransactionInterceptor 17:28:05,589 DEBUG [InstantiatedInterceptorHandler] Invoking interceptor InstantiateInterceptor 17:28:05,648 DEBUG [ToInstantiateInterceptorHandler] Invoking interceptor ParametersInstantiatorInterceptor 17:28:05,652 DEBUG [AsmBasedTypeCreator ] Trying to make class for ClientesController$lista$560765530$1 17:28:05,667 DEBUG [ParanamerNameProvider] Found parameter names with paranamer for ClientesController.lista() as [] 07/06/2010 17:28:05 org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet default threw exception java.lang.StringIndexOutOfBoundsException: String index out of range: 0 at java.lang.String.charAt(String.java:686) at br.com.caelum.vraptor.vraptor2.Info.capitalize(Info.java:62) at br.com.caelum.vraptor.http.asm.AsmBasedTypeCreator.typeFor(AsmBasedTypeCreator.java:85) at br.com.caelum.vraptor.reflection.CacheBasedTypeCreator.typeFor(CacheBasedTypeCreator.java:54) at br.com.caelum.vraptor.http.ognl.OgnlParametersProvider.createViaOgnl(OgnlParametersProvider.java:112) at br.com.caelum.vraptor.http.ognl.OgnlParametersProvider.createRoot(OgnlParametersProvider.java:108) at br.com.caelum.vraptor.http.ognl.OgnlParametersProvider.getParametersFor(OgnlParametersProvider.java:90) at br.com.caelum.vraptor.interceptor.ParametersInstantiatorInterceptor.getParametersFor(ParametersInstantiatorInterceptor.java:83) at br.com.caelum.vraptor.interceptor.ParametersInstantiatorInterceptor.intercept(ParametersInstantiatorInterceptor.java:68) at br.com.caelum.vraptor.core.ToInstantiateInterceptorHandler.execute(ToInstantiateInterceptorHandler.java:54) at br.com.caelum.vraptor.core.DefaultInterceptorStack.next(DefaultInterceptorStack.java:65)

Eu acho que é alguma coisa com a estrutura de arquivos do maven. A estrutura do projeto está assim:

src
–main
----java
------… ClienteController
----webapp
------WEB-INF
--------jsp
----------clientes
------------lista.jsp

Alguma sugestão?

EDIT =: achei que quem tinha feito o post era o lavieri, mas foi o lucas mesmo!

Lucas_Cavalcanti 8 de jun. de 2010

vc não precisa gerar um pom do vraptor, o vraptor já está no maven!

só colocar no pom da sua aplicação:

<dependency>
    <groupId>br.com.caelum</groupId>
    <artifactId>vraptor</artifactId>
    <version>3.1.2</version>
</dependency>

(talvez vc tenha que remover o jar q vc instalou na mão)

Lucas_Cavalcanti 8 de jun. de 2010

se isso não funcionar, vc pode detalhar um pouco mais o que tá acontecendo: qual url vc chamou e quais lógicas são executadas por ela?

mario.fts 8 de jun. de 2010

Cara funcionou, eu pensei que só tinha até a versão 3.1.1, pela demora que costuma ser pra subir projetos no repositório, nem tinha pesquisado.

Deve ser alguma dependencia q eu usei pro vraptor que tava dando pau.

Obrigado mais uma vez Lucas!
