Boa noite galera.... Primeiramente parabens por essa comunidade que ajuda em muito o desenvolvimento java no brasil.
estou comencando em java... e esse forum é sem comentarios....
pois bem, vamos ao problema que esta me deixando put* da vida.... ja procurei em diversos topicos... acho algo relacionado só que nao consigo resolver esse problema!
estou tentando integrar GAE com VRaptor através de JPA, porem nao consigo compilar... sempre me retorna erros.... pra deixar mais claro... minhas confg. estao assim.

tá dando uma NullPointer dentro do datanucleus… o persistence.xml está do jeito que eles recomendam?

danilo.rcte 22 de mai. de 2011

o codigo do persistence.xml é

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
        http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">

    <persistence-unit name="transactions-optional">
        <provider>org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider</provider>
        <properties>
            <property name="datanucleus.NontransactionalRead" value="true"/>
            <property name="datanucleus.NontransactionalWrite" value="true"/>
            <property name="datanucleus.ConnectionURL" value="appengine"/>
            <property name="datanucleus.appengine.autoCreateDatastoreTxns" value="false"/>
        </properties>
    </persistence-unit>

</persistence>

ja adicionei todos os jars no classpath… ja perdi as ideias para montar esse ambiente e faze-lo funcionar…
acredito que o pior problema do java é montar o ambiente…T.T,… to apanhando muito pra fazer esse projeto funcionar…
mais uma informacao: o sistema roda se eu tirar o vRaptor, utiliza-lo atraves de servlets… e jpa… , mas quando eu tento colocar os jars e as confg. do vRaptor… comeca me retornar esses erros… e vRaptor pelo que eu estava mechendo nele… é uma ferramenta extraordinaria para os projetos de web., e a ideia de desenvolver esse projeto criando os servlets na unha… sem injecao de dependencia, me deixa meio q … desanimado…huahahua

<context-param>  
        <param-name>br.com.caelum.vraptor.packages</param-name>  
        <param-value>br.com.caelum.vraptor.gae</param-value>  
    </context-param>  
<context-param>     
        <param-name>br.com.caelum.vraptor.provider</param-name>     
        <param-value>br.com.caelum.vraptor.util.jpa.JPACustomProvider</param-value>     
</context-param>

mude essas configurações para:

<context-param>  
        <param-name>br.com.caelum.vraptor.packages</param-name>  
        <param-value>br.com.caelum.vraptor.gae, br.com.caelum.vraptor.util.jpa</param-value>  
    </context-param>

se ainda assim não funcionar, tente tirar o pacote da jpa e criar as classes:

@Intercepts
public class CustomJPATransactionInterceptor extends JPATransactionInterceptor {
    //construtor delegate
    //sobrescreva o accepts se quiser fazer um controle de transações melhor
}

@Component
public class CustomEntityManagerCreator extends EntityManagerCreator {
   //construtor delegate
}

@Component
@ApplicationScoped
public class EntityManagerFactoryCreator implements ComponentFactory<EntityManagerFactory>{

	private EntityManagerFactory factory;

	@PostConstruct
	public void create() {
		factory = Persistence.createEntityManagerFactory("transactions-optional");
	}

	public EntityManagerFactory getInstance() {
		return factory;
	}

	@PreDestroy
	public void destroy() {
		factory.close();
	}

}

o vraptor por padrão usa o nome “default” pra persistence-unit, talvez seja por isso que não está funcionando

danilo.rcte 23 de mai. de 2011

ae lucas… consegui resolver… eu que tava comendo bola mesmo…kkkkkkk
malz ae…

principiante é uma merd*…hauhauah

Entao… como eu to fazendo o projeto no eclipse, eu estava colocando todos os jars… no war/web-inf/lib e depois eu importava todos aqueles jars no BuildPath… esse era o meu erro…

é preciso importar pro buildpath apenas o pacote vRaptor-XXX.jar

e pronto… funciona certinho… Valeu pela atencao…
