Subject [jira] [Created] (OPENJPA-2237) ElementCollection of Embeddable objects is resulting in a ClassCastException
Date Sat, 21 Jul 2012 21:17:34 GMT
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:
