Arquivo Discussoes de Programacao e Tecnologia Já baixei a apostila da caleum fj-28, mas não consigo roda na relacionado ao vraptor 3???
os exemplos da apostila relacionado a hibernat consegui fazer mas o vraport não consegui nada.
eu acho que é a configuração do eclipse e tomcat… gostaria que vocês me ajuda a configura eclipse e tomcat junto com os xml que precisa para roda aplicação.
Eu tava com o mesmo problema !
1 - Baixa o Eclipse GAlileu
2 - BAixa o MYDVDS.
3- IMPORTA O PROJETO
vai em novo servidor !
Instala o tom cat em runtime !
Roda !
bom, vc criou um Dynamic Web Project no eclipse?
colocou todos os jars que estão no vraptor-blank-project na pasta WebContent/WEB-INF/lib do seu projeto?
copiou o web.xml que está no blank project pro seu projeto?
configurou algum tomcat? (Preferences >> server runtimes >> new server >> tomcat)
clicou com o botão direito no projeto >> Run As >> Run On Server >> Tomcat ?
Eu já fiz todos os procedimentos que Lucas e outros usurário do forum passou mas mesmo assim não tive exceto, o interessante foi que eu executei da pasta WebContent qualquer arquivo .jsp e abriu normalmente no Firefox, mas dentro da pasta WebContent/WEB-INF/ não consigo executa!!!
agradeço as dicas mencionada.
vai ter que dar ! ou vai ou racha … vamos fazer via logme ou vnc ?
@eu.eu
vc tah acessando as jsps diretamente?
não é assim que funciona… jsps dentro do WEB-INF não são visíveis via web (na verdade nenhum arquivo dentro da WEB-INF)
vc tem que acessar as jsps a partir das lógicas do vraptor, ou seja, se vc tem um controller do tipo:
@Resource
public class BananaController {
public void macaco() {
}
}
vc vai acessar pela url http://localhost:8080/contexto_da_aplicação/banana/macaco e o resultado vai ser o jsp em WebContent/WEB-INF/jsp/banana/macaco.jsp
Deu até fome agora…
bom fiz o teste com vraptor-blank-project-3.1.2, e mostrou a pagina com a messagem "It works!! VRaptor! " ok.
mas quando faço com meu projeto não da certo, lembrendo que copiei todos os .jars para /lib. esta assim meu projeto:
Descobri que esta faltando web.xml....
não colocava o nome da classe:
não estava colocando o nome da classe
<display-name>br.com.caelum.goodbuy</display-name>
mesmo assim não mostar nada????
[color=blue]
meu código e este:[/color]
/src
-->br.com.caelum.goodbuy
-->Mundo.java
Codigo:
package br.com.caelum.goodbuy;
import javax.annotation.Resource;
public class Mundo {
@Resource
public void boasVindas(){
System.out.println("Óla mundo!!!");
}
}
o restante:
WebContent
-->WEB-INF
--> jsp
-->mundo
-->boasVindas.jsp

Pega o mydvds… apaga todas as classes dvd e dvdrental, deixa somente oque for referente a Usuario, pronto tu vai ter uma tela de login e senha, faz teu porjeto apos essa tela…
Obrigado pela dica, mas não quero copia projetos na web e depois reforma para meu projeto.
O que quero e aprende como funcionar a tecnologia vRaptor 3 e contruir aparte do zero “0”
Sim, dessa maneira vc não vai estar copiando nada, somente usando a BASE já configurada e funcional, se mudar o hibernate.cfg.xml para postgresql ou mysql vai funcionar, resumindo, através do mydvds você pode estudar toda a configuração e extrutura de Action do VR3…
Pegando o Projeto em Branco, você vai perder muito tempo, usando o Mydvds, já ajuda você ter bons resultados em dias !
grande abraço !
boa noite.
@eu.eu
vc usou o @Resource errado… o @Resource certo é o br.com.caelum.vraptor.Resource e ele tem que estar anotado na classe…
se ainda assim não funcionar, dá uma olhada se o eclipse tá compilando suas classes pra pasta WEB-INF/classes:
botão direito no projeto >> Properties >> Java Build Path >> Source >> o Default output folder tem que ser a pasta WebContent/WEB-INF/classes do seu projeto…
[]'s
Bom fiz os procedimento que você falou, mas ainda não esta certo???
package br.com.caelum.goodbuy;
import br.com.caelum.vraptor.Resource;
@Resource // fiz alteração que você pedio........
public class Mundo {
public void boasVindas(){
System.out.println("Óla mundo!!!");
}
}
em relação a [color=red]projeto >> Properties >> Java Build Path >> Source >> o Default output folder tem que ser a pasta WebContent/WEB-INF/classes do seu projeto…
[/color]
tava assim:
goodbuy/src
Alterei para :
goodbuy/WebContent/WEB-INF/classes
Obrigado mesmo, em me ajuda a descobri o que estou errando…
não entendi… deu certo ou não?
não…
o que acontece? que url vc tah acessando e o que está acontecendo?
o que tem dentro do seu WebContent/WEB-INF/jsp/mundo/boasVindas.jsp ?
Funcionou tava faltando eu colocar o endereço tipo:
http://localhost:8080/goodbuy/mundo/boasVindas
Só mas uma duvida, pra referencia uma arquivo.jsp tem que ter um classe com o mesmo nome tipo:
Classe --> Mundo.java que faz referencia WEB-INF/jsp/mundo.jsp
outro exemplo:
Classe --> Cadastro.java que faz referencia WEB-INF/jsp/cadastro.jsp
tem que ser assim.
toda .jsp tem que esta dentro da pasta /WEB-INF/jsp ????
Agradeço muito pela ajuda.
não… a regra é:
Classe ClienteController, metodo adiciona ==> URL /cliente/adiciona e JSP: WEB-INF/jsp/cliente/adiciona.jsp
Classe ProdutoController, metodo lista ==> URL /produto/lista e JSP WEB-INF/jsp/produto/lista.jsp
é o nome da classe anotada com @Resource sem a palavra Controller e a primeira letra minuscula, e o nome do método…
e sim, todo jsp tem que estar em /WEB-INF/jsp//.jsp
continua lendo a apostila do FJ-28, que essas coisas são explicadas com mais detalhes
Abraços
Cabe lembrar que o uso dos JSPs dentro de /WEB-INF/jsp/xxx.jsp é uma convenção do Vraptor. Nada impede você de futuramente sobrescrever esse comportamento.
Aliás qualquer componente no Vraptor possui essa facilidade de ser possível alterar seu comportamento.
Obrigado pela explicação. Vou continuar estudando a apostila da Caelum. Só tem um problema agora: depois que deu tudo certo vraptor o hibernate esta mostrando um erro, mas antes o hibernate tava funcionando:
og4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).
log4j:WARN Please initialize the log4j system properly.

ou seja, a classe br.com.caelum.goodbuy.modelo.Produto não existe… dá uma olhada pra ver se é esse mesmo o nome da classe e se ela tá no pacote certo.
Legal as explicações, vai dar uma facilitada aqui nas configurações também !!!
Desculpe a invasão “AGAIN”!
Tambem estou com problemas na mesma etapa, segui os exemplos e ainda não deu certo!
Poderia dar uma olhada no seguinte post?

Preciso de ajuda!
galera, eu to com o mesmo problema, eu não consigo visualizar meus jsp’s, e nem minha mensagem de olá mundo aparece no console . . . . . . . eu copiei as libs (depois de copia meu projeto fico com um ponto de exclamação vermelho) e peguei o web.xml do black-project do VRaptor, mas não deu certo
meu projeto chama Dashboard
minha classe chama Mundo (mesmo exemplo da apostila fj28)
package teste;
import br.com.caelum.vraptor.Resource;
@Resource
public class Mundo {
public void boasVindas(){
System.out.println("Isso é um teste");
}
}
meu jsp chama boasVindas e tá dentro de WEB-INF/jsp/mundo

coloque esse arquivo na sua pasta src:
e veja se aparecem os logs do VRaptor.
tá com uma warning nessa linha:

alguma informação útil nessas saídas???
de acordo com esse log ele só está considerando o IndexController, não olhou pra classe Mundo…
você criou ela no mesmo projeto do blank project?
esse ai é otro projeto, o nome dele é dashboard . . . . . . . . mais eu ainda tenho um projeto chamado blankproject no meu workspace
será que tem alguma coisa a ver com o contexto da minha aplicação???
o estranho é que quando eu tento acessa http://localhost:8080/dashboard/mundo/boasVindas o console não mostra nem o System.out.println(“isso é um teste”) que eu coloquei, não aparece nada mesmo
era pra colocar o log4j.xml no projeto do dashboard
foi lá que eu coloquei, mas continua não aparecendo nada no console, será que a url que eu to chamando é a certa??? existe algum modo além do deploy de muda o modo de chama a aplicação no browser???
o arquivo fica com a seguinte warning
The file cannot be validated as the XML definition “/home/fuckmaster/workspace/Dashboard/src/log4j.dtd (Arquivo ou diretório não encontrado)” that is specified as describing the syntax of the file cannot be located. log4j.xml
não sei se a warning é relevante
esse warning não muda nada…
se não apareceu nada no log, pode ser que ele esteja desconsiderando o seu web.xml…
o web.xml está no lugar certo? os jars estão em WEB-INF/lib? a pasta raiz web está configurada?(WebContent por exemplo) O projeto está dentro do servidor?
se sim, tenta dar cleans nos seus projetos e no servidor e tenta de novo.
Man, funciono \o/ . . . . . . eu tava vacilando, eu criei o projeto com primeira letra maiúscula, então o certo seria chama http://localhost:8080/Dashboard/mundo/boasVindas . . . . . . falha minha, vlw mesmo pela ajuda =D
Mais aproveitando que eu já to aqui, quando eu exportar o arquivo war, eu posso coloca o nome que eu aquise no arquivo, certo?? . . . . tipo oNomeQueEuQuero.war . . . . . . . ai pra chama é só usa http:///oNomeQueEuQuero/meusMetodo
É isso mesmo???
isso
novamente gostaria de um help galera . . . . . . eu consigo acessa minhas jsps agora porém dá erro 500 quando tento enviar minhas informações através do formulario
o formulário é esse ai
<body>
<form action="adiciona">

o meu controller é esse
package Controller;

}
public void remove(Projeto projeto) {
new ProjetoDao().remove(projeto);
}
public List<Projeto> lista() {
System.out.println("isso é um teste");
return new ProjetoDao().lista();
}
}
um detalhe . . . . . . o arquivo persistence.xml está na pasta WEB-INF, isso está certo???
vlw galera
se não falar qual foi o erro (exception) que deu não dá pra gente saber 
o persistence.xml precisa estar na pasta META-INF dentro do classpath (ex pasta src, ou src/main/resources)
Olá, desculpe a demora, vo posta os erros então
esse é o que aparece no console

o erro acontece quando tento fazer alguma operação relacionada ao hibernate, alguma informação útil ai??
Caused by: java.lang.NoSuchFieldError: INSTANCE
qdo dá esse tipo de erro (NoSuchField, NoSuchMethod, etc) geralmente é problema de versão de jar… vc provavelmente está com duas versões do hibernate, ou usando algum projeto do hibernate que precisa de uma versão diferente.
Man, eu reparei em otro vacilo meu . . . . . . . eu não tava instanciando meu Dao, agora o erro mudo

return session.createCriteria(Projeto.class).list();
}
}
e no controller, quem cria o dao? você recebe no construtor?
isso mesmo
package Controller;
import java.util.List;
import modelos.Projeto;
import modelos.ProjetoDao;
import br.com.caelum.vraptor.Resource;
import br.com.caelum.vraptor.Result;
@Resource
public class ProjetoController {
private ProjetoDao dao;
public ProjetoController() {
this.dao = dao;
}
public void formulario() {
}
public void adiciona(Projeto projeto) {
dao.adiciona(projeto);
}
public void atualiza(Projeto projeto) {
dao.atualiza(projeto);
}
public void remove(Projeto projeto) {
dao.remove(projeto);
}
public List<Projeto> lista() {
System.out.println("isso é um teste");
return dao.lista();
}
}
aqui:
private ProjetoDao dao;
public ProjetoController() {
this.dao = dao;
}
vc colocou o dao nele mesmo… precisa receber como parâmetro no construtor.
private ProjetoDao dao;
public ProjetoController(ProjetoDao dao) {
this.dao = dao;
}
o eclipse deve até ter te dado um warning, às vezes é importante ver isso
Putz, agora eu tomei essa exception aqui

deu algum pau na inicialização da classe HibernateUtil… deve estar no log de inicialização do servidor.
se vc está usa o VRaptor vc não precisa dessa classe, de qqer forma… vc pode registrar o pacote do hibernate e receber a Session direto no construtor do dao.
http://vraptor.caelum.com.br/documentacao/componentes-utilitarios-opcionais/
Man, eu to tentando usa o container do Spring, mas eu não sei como que eu configuro o VRaptor pra isso, e também não entendi o que eu tenho que coloca no CustomProvider, tem como dá uma esclarecida nisso ai???
vc não precisa configurar nada… basta ter os jars do spring no classpath…
vc não precisa do CustomProvider, só do context-param do packages com o valor do pacote do hibernate…
chegou a ler a apostila? http://www.caelum.com.br/curso/fj-28-vraptor-hibernate-ajax/
e fazer o curso? http://www.caelum.com.br/curso/online/vraptor/
Realmente eu não fiz o curso online, mas tava tentando acompanha a apostila quando deu todos esses erros . . . . . . . lendo a documentação mais atentamente eu percebi uns vacilos que eu tava cometendo por bobera . . . . . . vo rele tudo e i fazendo passo a passo
vlws 
Estou novamente com problemas . . . . . . eu recomecei meu projeto e acho que agora esta tudo certo, porém ocorrem erros quando tento starta o tomcat
abaixo está o erro e o meu web.xml
um help por favor

geralmente é problema de versão de jar. vê se tem mais de um jar do slf4j (tem que ter um slf4j e um slf4j-log4j)
tem um só de cada . . . . . . será que pode ter alguma coisa a ver com a versão???
e essas partes, não tem problema??

qual é a versão do slf4j que vc tá usando? tenta trocar a versão (ex usar a que vem com o vraptor)
a versão é essa ai, já era a mesma (slf4j-api-1.6.1.jar) mas eu subistitui todos os jars pelos que vem no vraptor, agora mudo o erro:
será incompatibilidade do log4j com a versão do hibernate??
o que eu acho estranho é ele não conseguir iniciar o contexto da aplicação

Blz, agora o problema é que não tem ninguém criando a Session do hibernate…
você pode criar um componente que faz isso, ou usar o que já vem com o VRaptor, no web.xml:
<context-param>
<param-name>br.com.caelum.vraptor.packages</param-name>
<param-value>br.com.caelum.vraptor.util.hibernate</param-value>
</context-param>
se já existir a configuração de packages, basta colocar os valores separados por vírgula
agora deu isso
GRAVE: Exception starting filter vraptor

eu tava usando o persistence.xml
ele não funciona???
se tá usando o persistence.xml troca o hibernate por jpa no context-param
Man, troquei por hibernate.cfg.xml e ele gera o código sql, mas ai deu otro erro estranho
pesquisei esse erro ai mas nenhuma das soluções deu certo =/

Então cara,
Não sei se vai te ajudar mas também achei a apostila nessa PARTE um pouco confusa.
Para instalar o Vraptor
Para Configurar o Hibernate usa um post do Blog da Caelum que não tem erro.
Abraços!
awe aquino.will, vlw, foi muito útil a parte de configura o hibernate
awe lucas, uma dica que vc deu em otro tópico já resolveu
funciono, eu tava tentando abri otra conexão
agora minha dúvida é otra, eu to com o list dessa forma
<c:forEach items="${projetoList}" var="projeto">
dá o seguinte exception
GRAVE: Servlet.service() for servlet jsp threw exception

parece que não tá aceitando expression language como type do foreach =/
vc deve ter importado a tag c errada…
o certo é esse:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
o.O . . . . . . . . . era isso mesmo . . . . . . . . vlw
cara, estou com o mesmo problema, você conseguiu resolver?
vc tentou a solução proposta nesse tópico?
