#1

Bom se eu coloco essa configuração utilitária no meu web.xml:

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

Dá o seguinte erro:

O que pode estar errado?

#2

vc tem um persistence.xml com a persistence unit chamada default?

#3

sim, o persistence-unit=“default”.
Também esta dando esse erro:

minha classe é essa:

[code]@Entity
public class Pessoa {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String nome;
private String sobreNome;

//mais os get e set
[/code]

#4

vc tá usando o plugin do eclipse pro AppEngine?

#5

sim estou, uso a ultima versão.

O engraçado é que já tive esse problema outra vez que tentei fazer algo no gae com o vraptor e tive o mesmo problema.

#6

isso tem a ver com uma parte de instrumentação de código que o datanucleus faz, e é uma das partes do build do eclipse pro gae… tenta ver se isso tá configurado direitinho

#7

Fiz um teste usando a mesma classe e o uma classe que cria o EntitiManager, do jeito que esta na documentação e funciona sem problema.

#8

Pior que eu não sei aonde esta as configurações do plugin.
Onde posso estar verificando isso?

#9

tenta pegar o exemplo da documentação e incluir os jars e classes do vraptor…

#10

Opa, criei um projeto novo e joguei os jars e configurei o web.xml para uso do vraptor, e ai funcionou.

Muito obrigado Lucas, mais uma vez.
