Hi,
I would like to find an object and then call EntityManager.remove for
removing it from the persistency context.
When i call find and specify the desired object's id i receive an object but
its id (the field i annotated with @Id) has a null value and therefore when
calling remove afterwards the JDBC query created behind the scenes looks for
a null value instead of the id i originally specified.
When debugging openjpa i found somewhere that there's some configuration for
copying identity fields or something....
Help!
Thanks,
Idan
My code:
_em.getTransaction().begin();
SimplePerson p = (SimplePerson) _em.find(SimplePerson.class,
100);
_em.remove(p);
_em.getTransaction().commit();
My class looks like this:
@Entity
@Table(name = "SimplePerson")
public class SimplePerson {
@Id
private Integer id;
@Basic
private String name;
@Basic
private String address;
@Basic
private String email;
public SimplePerson(Integer id) {
this(id, "SimplePerson #" + id, "SimplePerson # " + id + "
Address",
"SimplePerson" + id + "@temp.com");
}
public SimplePerson(Integer id, String name, String address, String
email)
{
this.id = id;
this.name = name;
this.address = address;
this.email = email;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
