Hello all,
I'm trying to teach myself OpenJPA and failing miserably... I have two
entities (code below) where one contains a collection of the other. The intent
is for UserInfo to be able to contain a collection (or List) of an arbitrary
number of UserProperties. The UserProperties are defined at run-time by data
entered through the application.
With it defined as follows in the ear file deploys fine in Geronimo, but
calling any of the service methods that try to query or insert data result in
the following errors:
javax.ejb.EJBException: The bean encountered a non-application exception.;
nested exception is:
<openjpa-1.0.2-r420667:627158 fatal user error>
org.apache.openjpa.persistence.ArgumentException: You have supplied columns for
"com.whitetail.sawhorse.data.UserInfo.userProperties", but this mapping cannot
have columns in this context.
The relevant portion of the entities are defined as:
@Entity
@Table(name="userinfo")
public class UserInfo implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="id", nullable=false, insertable=false, updatable=false)
private Integer id;
@OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL)
@JoinColumn(name="prop_id", referencedColumnName="userId")
private Collection<UserProperties> userProperties;
and
@Entity
@Table(name="userproperties")
public class UserProperties implements Serializable {
@Id
@Column(name="id", nullable=false)
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
@OneToOne(fetch=FetchType.LAZY)
@JoinColumn(name="user_id", referencedColumnName="id")
private UserInfo userInfo;
I thought I had it right according to the documentation and the few examples
I've seen, but I've got something wrong. Any help getting this solved would be
greatly appreciated.
Cheers!
Randy
