Olá galera estou fazendo alguns testes com VRaptor e me deparei com o seguinte erro. Tenho as seguintes classes:

@Component
public class PersonRepository extends RepositoryImpl implements PersonRepositoryIF {

public PersonRepository(){
	this.clazz = Person.class;
}

@Override
public PageResult find(Filtro filtro) {
	return null;
}

}

Na Classe RepositoryImpl tenho o meu EntityManager da seguinte forma:

@PersistenceContext
protected EntityManager em;

No controller está assim:

@Resource
public class PersonController{

private PersonRepositoryIF repository;
@SuppressWarnings("unused")
private final Result result;

@Autowired
public PersonController(PersonRepositoryIF _repository, Result _result){
	this.repository = _repository;
	this.result = _result;
}

@Transactional(propagation=Propagation.REQUIRED, rollbackFor=Exception.class)
@Path("/person/listar")
public List<Person> list(){
	return repository.listOrder(new String[]{"firstName"});
}

}

web.xml:

<?xml version="1.0" encoding="UTF-8"?>

Com essa mesma configuração adicionando apenas no web.xml os listener: ContextLoaderListener, RequestContextListener e o caminho para o meu applicationContext.xml, o funciona com o Struts2 e JSF. Uma coisa que vi é que quando a aplicação inicia é como o VRaptor não inicializasse o applicationContext.

Alguém sabe qual o possivel erro?

Desde já agradeço.

onde vc colocou o applicationContext.xml? ele está no classpath?

A
alberto.mxs

Bom dia, o applicationContext.xml está na pasta: WEB-INF/applicationContext.xml.

Lucas_Cavalcanti
Lucas_Cavalcanti

pro applicationContext.xml ir pro classpath vc precisa colocá-lo em alguma src folder… por exemplo a pasta src do seu projeto

seufagner
seufagner

então ele não está no classpath… ele deve estar ficar abaixo do diretório WEB-INF/classes

de qualquer forma, voce nao precisa configurar tudo isto, pois o VRaptor ja tem componentes utilitarios que o faz pra vc
