我真的不使用JPA ...所以這更像是一個基本的問題使用JPA2一個實體更新
我用JPA2 - (不冬眠)
我有這樣的功能,我要讓我的
@RequestScoped // (this is javax.faces.bean.RequestScoped)
@Stafeful // (this is javax.ejb.Stateful)
public class MyProvider {
@Inject
private EntityManager entityManager;
/* some variables and getters and setters */
public void setLocked(Long id, boolean locked) {
entityManager.getTransaction().begin();
user = userProvider.findUserByID(id);
user.setLocked(locked);
entityManager.persist(user);
// i also tried it with refresh instead of persist
entityManager.refresh(user);
entityManager.getTransaction().commit();
}
}
的更新,但我在這一點上 entityManager.getTransaction()得到這個錯誤開始()。

我也看過this文章 - 但它並不能真正幫助,但它仍然拋出:javax.persistence.TransactionRequiredException: no transaction is in progress
我不知道如果我做一些必要的錯......
