Eu Coloquei no META-INF, mais coloquei no WEB-INF pra fazer um teste
tira o @RequestScoped do metodo dessa classe pra teste
public class JPAUtil {
private static EntityManagerFactory emf = Persistence
.createEntityManagerFactory("tributoProduto");
@Produces
//@RequestScoped //tire o requestscoped
public EntityManager getEntityManager() {
return emf.createEntityManager();
}
public void close(@Disposes EntityManager em) {
em.close();
}
}
e vê se muda a mensagem
tirei o @RequestScoped e nada…
vou colocar as libs, só pra desencargo
o seu EntityManagerFactory está static ainda ?
se estiver, põe um @Producer… e de quebra põe ele com o @ApplicationScoped para ser criado uma só vez
private EntityManagerFactory emf;
@Produces @ApplicationScoped
public void createEMF(EntityManagerFactory emf){
this.emf = emf
}e você pode também adicionar um @Dispose para fechar automágicamente a sua fábrica
public void createEMF(@Dispose EntityManagerFactory emf){
emf.close();
}velhinho faz o seguinte
vc disse que esta usando a versão 2.0 do weld
troca pra versão 1.1 final
a versão 2.0 é um beta ainda
Voltei pro Weld 1.1, mais voltou o erro inicial do nullPointer.
Era pra ser tão difícil assim?
não era não,
coloca o log do erro atual e o codigo das classes apos as alterações
ok, valeu Danilo, você está me ajudando muito.
public class JPAUtil {
private static EntityManagerFactory emf = Persistence
.createEntityManagerFactory("tributoProduto");
@Produces

Class classe = (Class) parameterizedType.getActualTypeArguments()[0];
return new DAO(classe);
}
}Acabei de notar que esse bean, no método getulista(), passa um DAO pra outra Classe;
@Named
@ViewScoped
public class CidadeBean implements Serializable {
@Inject
private Cidade cidade;
@Inject
private DAO<Cidade> dao;
private LazyDataModel<Cidade> lista;
public void grava() {
if (this.cidade.getId() != null)
dao.atualiza(this.cidade);
else
dao.adiciona(this.cidade);
this.cidade = new Cidade();
}
public LazyDataModel<Cidade> getLista() {
if (lista == null) {
lista = new DataModel<Cidade>(dao);
}
return lista;
}public class DataModel<T> extends LazyDataModel<T> {
private static final long serialVersionUID = 1L;
private List<T> lista;
private DAO<T> dao;
public DataModel(DAO<T> dao) {
this.dao = dao;
}
//Restante da Classe
}cria um novo construtor aqui no DAO que vai receber a Classe e o EntityManager
public class DAO<T> implements Serializable {
private static final long serialVersionUID = 1L;
private final Class<T> classe;
public DAO(Class<T> classe, EntityManager em) { // construtor com o entitymanager
this.classe = classe;
this.em = em;
}
@Inject // pode tirar o inject daqui ele não sera mais necessario
private EntityManager em;
public void adiciona(T t) {
em.getTransaction().begin();
em.persist(t);
em.getTransaction().commit();
}
} na fabrica usa o novo construtor
public class DAOFactory {
@Inject
private EntityManager em;
@SuppressWarnings({ "rawtypes", "unchecked" })
@Produces
@Dependent
public DAO create(final InjectionPoint injectionPoint) {
ParameterizedType parameterizedType = (ParameterizedType) injectionPoint
.getType();
Class classe = (Class) parameterizedType.getActualTypeArguments()[0];
return new DAO(classe, em);
}
} lembra o que eu falei antes, quando vc da new o conteiner não vai injetar as dependências que a classe venha precisar por isso vc deve passar pra classe essa dependência
se agente parar pra analisar vamos perceber que o cdi não tem como construir a classe DAO sozinha porque ele vai depender de onde vai ser injetada por isso criamos a fabrica
mas não adianta vc construir o dao passando a classe não passar o entitymanager tambem por que como estamos dando new no dao o cdi não vai injetar o entitymanager
Agora que eu entendi, funcionou Certinho…
Muito Obrigado pela ajuda de todos em especial o DaniloAndrade.
Abraços!
show, posta como resolvido o post.

Olá Boa Tarde!
Prezados estou passando pelo problema só que já apliquei a solução aqui desenvolvida mais não tive sucesso alguem poderia me dar uma força segue o erro.

Notei que no log menciona algo a respeito de qualificadores, não fiz nada disto estou bem no começo do projeto e só queria ver a execução do mesmo mostrando a unica pagina que tenho e ver as tabelas no banco serem criadas pelo Hibernate mais num funfou mesmo seguindo aqui as explicações dadas pelo Sr. Danilo.
O Projeto usa JSF 2.2, JPA, Hibernate 4.3
PessoALL,
Fiz tudo como manda o figurino… mas estou com um problema aqui;

@Log

...estou tomando o erro logo na inicialização do Tomcat (log de erro completo abaixo);
E agora? como fazer?

GRAVE: The web application [/portal] appears to have started a thread named [weld-preloader-3] but has failed to stop it. This is very likely to create a memory leak.

Prezado eu tava com os meus estudo parado mesmo mais apos este período eu observei uma videos aulas e estou voltando ao meu projeto, estou refazendo ele agora usando o Maven e não esta dando nenhum problema ( do que vc esta relatando ) infelizmente eu não sou a pessoa ideal para tirar duvidas rsrsrsrs.
Com certeza alguém com maior experiencia deve dar um retorno, só aproveitei a deixa pra comentar uma vez que estou voltando ao projeto
Você está usando CDI 1.1? se sim, precisa trocar o código do seu produtor para algo assim:
public class DAOFactory
{
@Inject
private EntityManager em;
@Produces
@SuppressWarnings({ "unchecked", "rawtypes" })
public <T> GenericDAO<T> create(InjectionPoint injectionPoint)
{
ParameterizedType type = (ParameterizedType) injectionPoint.getType();
Class classe = (Class) type.getActualTypeArguments()[0];
return new GenericDAO(classe, em);
}
} Faz a alteração e veja se resolve.
Olá Prezados bom dia.
Queria tirar uma duvida, quando se tem um projeto com CDI temos os Jar´s cdi-api.jar e weld-servlet.jar do Weld e que eu entendo que se trata de CDI pelo que eu estudei , agora estou iniciando um projeto que nas dependências do maven eu tenho o javax.inject que corresponde ao javax.inject-1.jar e faço nele eu utilizo as anotações @named e @inject e não tenho os jar´s mencionados anteriormente, isto esta me deixando confuso alguém poderia comentar sobre?
Qual a dependencia do maven? coloca o pom ae
Olá Mario bom dia!
Então é um projeto de estudo antigo que eu utilizava com Spring, com a introdução do CDI “Use CDI no seu próximo projeto” eu resolvi fazer isto sem o Spring com o Weld e me dei mal não consegui, passado-se muitos meses eu observei umas aulas na net e resolvi voltar a um novo projeto usando CDI mais com o Spring mais, o JSF 2.2 é o cara e não o Spring MVC, o que me intrigou foi que na video aula há a injeção mais não tem weld e isto me confundiu e queria tirar esta duvida se eu vou precisar do weld também ou não.
O projeto tá no inicio, tá funcionando o unico problema que vi é com a mensagem do faces o h:message acho que não tá existindo o contexto do faces., bem mais ai vai o pom ou melhor parte dele.

</dependencies>O javax.inject é de uma spec chamada DI (https://jcp.org/en/jsr/detail?id=330) que é diferente do CDI (https://jcp.org/en/jsr/detail?id=299 e https://jcp.org/en/jsr/detail?id=346).
Na spec de DI só é definida a annotations @Inject e algumas outras, mas não possui as annotations de escopo por exemplo. Essa spec DI o Spring suporta, por isso seu código funciona com ele. Pro Spring usar @Inject tem o mesmo efeito de usar @Autowired. Além do Spring o Guice também suporta esta spec.
