Pessoal Estou com uma dúvida aqui em relação a organização e pastas do projetos, mais precisamente dos arquivos .jsp

Tenho a seguinte estrutura:

customer/broker/gridView.jsp
customer/broker/formView.jsp

No meu controller está anotado da seguinte maneira:

@Resource
@Path("/customer/broker")
public class BrokerController

Metodo:

@Get
@Path("/gridView")
public void gridView()

Quando chamo a seguinte url: “customer/broker/gridView” ele não encontra o recurso mostrando o link abaixo.

/einsurance/WEB-INF/jsp/broker/gridView.jsp

isso é algum tipo de configuração ou tenho que montar uma função de resolução de path?

valeu galera!

@Path indica qual URI está referenciando àquele método. Ou seja, seu método BrokerController.gridView() será chamando quando a URI /customer/broker/gridView for acessada.

Após finalizar na action será feito um forward para o JSP /WEB-INF/jsp/broker/gridView.jsp independente do Path usado. Ou seja, o que conta para o nome do JSP é o nome do controller e do método e não o @Path usado.

Obvio, isso é a configuração padrão, e você pode sobrescrever conforme for necessário.

/einsurance/WEB-INF/jsp/broker/gridView.jsp

Não entendi… você tem um link na página que aponta para esse local? Isso não funciona, você sempre deve acessar os JSPs pelas actions, e nunca o JSP direto.

vc precisa que seja essa a estrutura?

customer/broker/gridView.jsp
customer/broker/formView.jsp

não pode mover isso pra:

WEB-INF/jsp/broker/gridView.jsp
WEB-INF/jsp/broker/formView.jsp

djDufu 8 de jul. de 2010

Valeu pelas respostas pessoal.

Lucas a questão é que se eu deixar WEB-INF/jsp/broker/gridView.jsp o projeto ficará muito desorganizado, pois tenho dentro de customer algo em torno de 15 sub categorias entre outras.

na verdade minha sestrutura de paginas ficaria algo assim:

customer
   Broker
   Partner
   Subsidiary
   Channel
Policy
    blablablablabla
    blablablablabla
         blablablablabla
         blablablablabla
Products
Sales

e assim vai.

eu vou supor que vc vai usar o @Path que está na classe do seu controller pra decidir o prefixo dos jsps, vc mude isso se vc quiser…

crie uma classe com o mesmo conteudo dessa, só que com outro nome, num pacote da sua aplicação e anotada com @Component:

github.com

caelum/vraptor/blob/master/vraptor-core/src/main/java/br/com/caelum/vraptor/view/DefaultPathResolver.java

package br.com.caelum.vraptor.view;

import br.com.caelum.vraptor.http.FormatResolver;

This file has been truncated. show original

mude o método getPrefix para

protected String getPrefix(ResourceMethod method) {
    Path path = method.getResource().getType().getAnnotation(Path.class);
    return path.value();
}

daí seus jsps podem ficar relativos à pasta configurada no @Path da classe do controller

Valeu, Lucas.

o return path.value(); está nulo.

Lucas_Cavalcanti 8 de jul. de 2010

bom, retorna “/WEB-INF/jsp” qdo não vier o value então… ou qqer outro path que vc queira que seja o padrão…

o path.value() vai vir uma String[], que são as paths q vc colocou na anotação… usa isso pra retornar o que vc quer…

djDufu 8 de jul. de 2010

Lucas,

a função pathFor retorna getPrefix(method) + folderName + “/” + method.getMethod().getName()

porém a função getPrefix retornará minha nova notação /customer/broker e o foldername retorna o nome extraido do controller obtendo o seguinte resultado:

/einsurance/customer/brokerbroker/gridView.jsp

Lucas_Cavalcanti 9 de jul. de 2010

só remover o folderName…

pode mexer em todas as lógicas de montar os caminhos… só cuidado pra não mexer nas outras lógicas…

vc pode deixar essa classe do jeito que vc quiser

djDufu 13 de jul. de 2010

Cara valeu mesmo,

Fiz várias alterações na classe para tratar diferentes niveis.

Muito obrigado.

abs,

Eduardo Venâncio.
