Alguém poderia disponibilizar um exemplo funcional do VRaptor 4 com injeção de dependências para jpa?
você vai usar tomcat/jetty ou um servidor de aplicação, como o Wildfly ou glassfish?
se for servidor de aplicação, basta receber o persistenceContext na classe que vc quer:
@PersistenceContext
private EntityManager managere colocar @Transactional na classe.
Se for tomcat/jetty, use o plugin vraptor-jpa https://github.com/caelum/vraptor-jpa e receba o EntityManager com @Inject.
Estou usando o Tomcat,
Fiz isso mas estou recebendo o erro:

Troquei o beans.xml para src/main/resources/WEB-INF. ai nao acessa os controlles nenhum get.
IndexController is not proxyable because it has no no-args constructor
vc precisa adicionar um construtor sem argumentos em todas as classes que recebem injeção pelo construtor.
o plugin da jpa é um outro jar que vc coloca na aplicação, não é mais só colocar aquelas linhas no web.xml.
PS: coloque os códigos entre e
Lucas muito obrigado pela ajuda!!!
Resolvido tudo .
Solução:
Troquei o plugin para o vraptor-jpa 4.0.0-RC2
e acrescentei na classe controller o construtor sem argumentos
/**
* @deprecated CDI eyes only
*/
public IndexController() {
this(null, null);
}Nota* esta funcionando com “beans” em /src/main/resources/META-INF/beans.xml
não funcionou com ele na pasta WEB-INF
esse é o lugar certo dele mesmo, em src/main/resources/META-INF
Lucas tenho uma duvida, quando tentei fazer as injects com minha própria class Dao não funciono conforme erros acimas, depois de funcionar com o plugin peguei o código dele e coloquei em meu pacote novamente da o mesmo erro por que funciona no plugin e não funciona no código, estou perguntando para entender por que o CDI não esta lendo minhas class comentada com Produces ?
não sei se eu entendi o que vc quis dizer.
toda classe precisa ter um construtor sem argumentos, por causa do CDI.
que erro está dando? vc copiou exatamente as classes do plugin e deu erro na sua app?
o que vc quer dizer com comentada com Produces? não seria anotada?
Sim copiei exatamente as classes do plugin e da o erro
se troco o beans para WEB-INF não da erro mas o Vraptor para de funcionar! nao responde a nenhum solicitação embora no debug mostra que ele subiu
não troca o beans.xml de lugar, ele tem que estar em src/main/resources/WEB-INF/
vc copiou a classe do plugin que tem o @Produces de EntityManager?
Então e isso que eu estou falando ele vem no vraptor-blank-project no path src/main/resources/META-INF/
dessa forma funciona com o plugin se mudar para WEB-INF nao funciona quando copie as classes EntityManagerFactory, EntityManagerFactoryCreator, JPATransactionInterceptor sem mudar o beans para WEB-INF aparece o erro
se coloco o beans na pasta WEB-INF não aparece o erro mas o vraptor não reconhece as request para os controller, ele nem configura meu controller e metodos.
Tenta colocar um breakpoint nos métodos que tem @Produces do plugin e subir o servidor em modo de debug.
Veja se está passando por lá.
Aparece algum log do hibernate ou do plugin no console do servidor?
Não para fazer o teste eu removi o plugin estou tentando rodar só com as classes do plugin copiada para o projeto com o plugin esta rodando
nenhum log
com o plugin está rodando? qual é o problema então?
Finalmente encontrei o erro, coloquei as classes do plugin dentro do pacote br.com.caelum.vraptor.util do meu projeto, o grande problema é que o vraptor tem uma pacote chamado br.com.caelum.vraptor.util e por algum motivo deu todos esses erros, depois de quebrar bastante a cabeça troquei o nome do pacote e tudo funcionou perfeitamente , obrigado ao Lucas por todo o interesse em ajudar.
