"detached entity passed to persist error" with JPA/EJB code
- by zengr
I am trying to run this basic JPA/EJB code:
public static void main(String[] args){
UserBean user = new UserBean();
user.setId(1);
user.setUserName("name1");
user.setPassword("passwd1");
em.persist(user);
}
I get this error:
javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.PersistentObjectException: detached entity passed to persist: com.JPA.Database
Any ideas?
I search on the internet and the reason I found was:
This was caused by how you created the objects, i.e. If you set the ID property explicitly. Removing ID assignment fixed it.
But I didn't get it, what will I have to modify to get the code working?
