[jira] [Created] (OPENJPA-2237) ElementCollection of Embeddable
objects is resulting in a ClassCastException
Mark Youwanes created OPENJPA-2237:
--------------------------------------
Summary: ElementCollection of Embeddable objects is resulting in a ClassCastException
Key: OPENJPA-2237
URL: https://issues.apache.org/jira/browse/OPENJPA-2237
Project: OpenJPA
Issue Type: Bug
Components: jpa
Affects Versions: 2.2.0
Environment: Latest Spring Data JPA for defining repository (dao) to retrieve the data. MySQL 5.5 database. Spring MVC.
Reporter: Mark Youwanes
I have a model that is very similar to the following, which taken straight from the Pro JPA 2 book by Mike Keith (page 108):
package emp;
import java.util.Collection;
import java.util.Set;
import javax.persistence.ElementCollection;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
@Entity
public class Employee {
@Id
private int id;
private String name;
private long salary;
@ElementCollection(targetClass = VacationEntry.class, fetch = FetchType.EAGER)
private Collection VacationBookings;
public Collection getVacationBookings() {
return VacationBookings;
}
}
package com.kryterion.wa.core.model.emp;
import java.util.Calendar;
import javax.persistence.Column;
import javax.persistence.Embeddable;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
@Embeddable
public class VacationEntry {
@Temporal(TemporalType.DATE)
private Calendar startDate;
@Column(name = "DAYS")
private int daysTaken;
}
CREATE TABLE IF NOT EXISTS`EMPLOYEE`(
`ID` int(11) NOT NULL AUTO_INCREMENT,
`NAME` varchar(255) NOT NULL,
`SALARY` bigint(15),
PRIMARY KEY (`ID`)
);
CREATE TABLE IF NOT EXISTS`EMPLOYEE_VACATIONBOOKINGS`(
`EMPLOYEE_ID` int(11) NOT NULL,
`STARTDATE` DATE,
`DAYS` int(11),
PRIMARY KEY (`EMPLOYEE_ID`,`STARTDATE`,`DAYS`)
);
ALTER TABLE EMPLOYEE_VACATIONBOOKINGS ADD CONSTRAINT EMPLOYEE_VACATIONBOOKINGS_FKC FOREIGN KEY (EMPLOYEE_ID) REFERENCES EMPLOYEE (ID);
Simply insert an employee and then some sample vacation entries for that employee to test it out.
When I retrieve an Employee object, as follows:
//...within my spring controller annotated with @Controller
@Inject
private EmployeeRepository empRepo;
....
Employee emp = empRepo.findOne(1);
I end up with the following exception:
org.springframework.orm.jpa.JpaSystemException: [Ljava.lang.Object; cannot be cast to org.apache.openjpa.enhance.PersistenceCapable; nested exception is <openjpa-2.2.0-r422266:1244990 nonfatal general error> org.apache.openjpa.persistence.PersistenceException: [Ljava.lang.Object; cannot be cast to org.apache.openjpa.enhance.PersistenceCapable
