Wolfgang Winter commented on OPENJPA-1607:
------------------------------------------
Hi,
I also observe the exception on Tomee 1.6:
<openjpa-2.3.0-nonfinal-1540826-r422266:1542644 fatal user error>
org.apache.openjpa.persistence.ArgumentException:
You have supplied columns for
"com.logitags.cibet.actuator.archive.Archive.resource.com.logitags.cibet.core.Resource.parameters",
but this mapping cannot have columns in this context.
at
org.apache.openjpa.jdbc.meta.MappingInfo.assertNoSchemaComponents(MappingInfo.java:382)
with the mappings listed below. It is working without problems on
Glassfish/Eclipselink without join table.
Is there any solution for this issue?
@Entity
public class Archive implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE, generator = "CIB_SEQUENCE")
@TableGenerator(name = "CIB_SEQUENCE", table = "CIB_SEQUENCE", pkColumnName
= "SEQUENCE", valueColumnName = "HI", pkColumnValue = "Archive", allocationSize
= 1)
private long archiveId;
@Embedded
@AssociationOverride(name = "parameters", joinColumns = @JoinColumn(name =
"archiveId", referencedColumnName = "archiveId"))
private Resource resource;
}
@Entity
public class DcControllable implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long dcControllableId;
@Embedded
@AssociationOverride(name = "parameters", joinColumns = @JoinColumn(name =
"dcControllableId", referencedColumnName = "dcControllableId"))
private Resource resource;
}
@Embeddable
public class Resource implements Serializable, Cloneable {
@OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY)
@JoinColumn(name = "dummy")
private List<ResourceParameter> parameters = new
LinkedList<ResourceParameter>();
}
