I am getting an exception when trying to save an object and its associated child objects.

I have the following objects

Person
PersonEmailAddr
Event
PersonEvent
PersonEvenPK

I am able to successfully persist the Person and its associated object PersonEmailAddr which is a one to many relationship.
The code for that is as follows
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();

Person person = new Person();
person.setAge(51);
person.setFirstname("George");
person.setLastname("Matt");
Set emailSet = new HashSet();

PersonEmailAddr email = new PersonEmailAddr();
email.setEmailAddr("matt@dbb.com");
email.setPerson(person);
emailSet.add(email);
person.setPersonEmailAddrs(emailSet);

session.save(person);
session.getTransaction().commit();

But if i try to persit the Event which is having a many to many relation with Person as follows it throws an exception.
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();

Person person = new Person();
person.setAge(51);
person.setFirstname("George");
person.setLastname("Matt");
Set emailSet = new HashSet();

PersonEmailAddr email = new PersonEmailAddr();
email.setEmailAddr("matt@dbb.com");
email.setPerson(person);
emailSet.add(email);
person.setPersonEmailAddrs(emailSet);


Event event = new Event();
event.setEventDate(new Date());
event.setTitle("Dance");

Set personEventSet = new HashSet();
PersonEventPK primaryKey = new PersonEventPK();
primaryKey.setEvent(event);
primaryKey.setPerson(person);
PersonEvent personEvent = new PersonEvent();
personEvent.setComp_id(primaryKey);
personEventSet.add(event);

event.setPersonEvents(personEventSet);
person.setPersonEvents(personEventSet);


session.save(person);
session.getTransaction().commit();

Can any one help.. I am giving all the mapping and exceptions below

Best Regards

Exception in thread "main"

What does PersonEvent.getComp_id() look like? That's what's throwing the exception.

Please use code tags. Or at least preview your post.

I am sending the PersonEvent class code. I dont find any problem with the getComp_id method

package com.infra.persistence.bean;

import java.io.Serializable;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import org.apache.commons.lang.builder.ToStringBuilder;

/** @author Hibernate CodeGenerator */
public class PersonEvent implements Serializable {

/** identifier field */
private com.infra.persistence.bean.PersonEventPK comp_id;

/** full constructor */
public PersonEvent(com.infra.persistence.bean.PersonEventPK comp_id) {
this.comp_id = comp_id;
}

/** default constructor */
public PersonEvent() {
}

public com.infra.persistence.bean.PersonEventPK getComp_id() {
return this.comp_id;
}

public void setComp_id(com.infra.persistence.bean.PersonEventPK comp_id) {
this.comp_id = comp_id;
}

public String toString() {
return new ToStringBuilder(this)
.append("comp_id", getComp_id())
.toString();
}

public boolean equals(Object other) {
if ( !(other instanceof PersonEvent) ) return false;
PersonEvent castOther = (PersonEvent) other;
return new EqualsBuilder()
.append(this.getComp_id(), castOther.getComp_id())
.isEquals();
}

public int hashCode() {
return new HashCodeBuilder()
.append(getComp_id())
.toHashCode();
}

}

thanks in advance

I can tell you what's happening, but not why. PersonEvent.getComp_id is being called (through reflection) on an object that isn't a PersonEvent. It's quite possibly due to something in your mapping. Unfortunately your mapping is really hard to read (you didn't use code tags), so I can't see what's wrong. I'd check all references to the PersonEvent and PersonEventPK classes and ensure that you're referring to the correct one at all times in your mapping.

The fact that Person refers to PersonEvent via a single column key (person_id in the personEvents set) is a warning sign, to me. After all, you've defined PersonEvent's primary key to be two columns (event_id, person_id). I'd start with that.

Actually i have made a mistake at first

The following was the section of the code where i made the mistake
Set personEventSet = new HashSet();
PersonEventPK primaryKey = new PersonEventPK();
primaryKey.setEvent(event);
primaryKey.setPerson(person);
PersonEvent personEvent = new PersonEvent();
personEvent.setComp_id(primaryKey);
personEventSet.add(event); //and this was the line i was making the mistake. It should have been

personEventSet.add(personEvent);

Actually your answer gave me the pointer. Thank you very much for that pointer.

But still the issue was not solved and i was getting nullpointer exception. But when i tried the session.saveorUpdate() for persisting the person and event class and then finally persisted person class it worked perfectly fine. I will put the code which worked and specifically mark the changes in cold in bold letters
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();

Person person = new Person();
person.setAge(51);
person.setFirstname("George");
person.setLastname("Matt");
Set emailSet = new HashSet();

PersonEmailAddr email = new PersonEmailAddr();
email.setEmailAddr("matt@dbb.com");
email.setPerson(person);
emailSet.add(email);
person.setPersonEmailAddrs(emailSet);

session.saveOrUpdate(person); // this is where my lack of hibrernate knowledge caused problem

Event event = new Event();
event.setEventDate(new Date());
event.setTitle("Dance");

session.saveOrUpdate(event); // this is where my lack of hibrernate knowledge caused problem

Set personEventSet = new HashSet();
PersonEventPK primaryKey = new PersonEventPK();
primaryKey.setEvent(event);
primaryKey.setPerson(person);

PersonEvent personEvent = new PersonEvent();
personEvent.setComp_id(primaryKey);
personEventSet.add(personEvent); // this was where i made the programming error due to my carelessness

event.setPersonEvents(personEventSet);
person.setPersonEvents(personEventSet);

session.save(person);

session.getTransaction().commit();

Thanks a lot for help.

One more thing you mentioned i didnt put some code tag and it made my mappings difficult to read. Acutally i didnt understand what you meant. Can you tell me what is that. I am new to the forum so can you please telll me what does that mean

Code tags make codeMuch easier to read, fixed with font etc. Put "[code]" before your text and "[/ code]" (no space) after, or press the "code" button above the text area.
