Hi,
I need some help to solve some problem to map a many-to-many relationship. Finally I have introduced a new table so I have two relationships with this join table of one-to-many type:

RegistreEvents(1)------(N)EventsComunicats(N)------(1)DadesPersonals

I've shortened the code to avoid wasting your time:

public class RegistreEvents {
private int identifier;
private String subject;
private String body;
private modulInformacioEvents.RegistreEvents event;
private modulPersonal.DadesPersonals fromWho;
private java.util.Collection toWhom = new java.util.TreeSet();
...
}

public class EventsComunicats {
private DadesPersonals persona;
private Events eventId;
...
}

public class DadesPersonals {
private int identifier;
private String nom;
private String cognom1;
private String cognom2;
private String DNI;
private java.util.Collection email = new java.util.TreeSet();
private java.util.Collection telefons = new java.util.TreeSet();
private java.util.Collection registraEvent = new java.util.TreeSet();
private java.util.Collection repEvent = new java.util.TreeSet();
...
}

And the following XML stuff is how I mapped this classes:

<hibernate-mapping package="modulInformacioEvents">
<class name="RegistreEvents" table="RegistreEvents">
<id name="identifier" column="identifier" />
<property name="subject" column="subject" />
<property name="body" column="body" />
<many-to-one name="event" column="identifier" class="Events" />
<many-to-one name="fromWho" column="identifier" class="DadesPersonals" />
<set name="toWhom" inverse="true">
<key column="eventId" />
<one-to-many class="EventsComunicats" />
</set>
</class>
</hibernate-mapping>


<hibernate-mapping package="modulInformacioEvents">
<class name="EventsComunicats">
<composite-id name="identifier" class="EventsComunicats">
<key-property name="eventId" column="eventId" />
<key-property name="persona" column="persona" />
</composite-id>
<many-to-one name="eventId" class="RegistreEvents" column="identifier" />
<many-to-one name="persona" class="DadesPersonals" column="identifier" />
</class>
</hibernate-mapping>


<hibernate-mapping package="modulPersonal">
<class name="DadesPersonals" table="DadesPersonals">
<id name="identifier" column="identifier" />
<property name="nom" column="nom" />
<property name="cognom1" column="cognom1" />
<property name="cognom2" column="cognom2" />
<property name="DNI" column="DNI" />
<set name="correuelectronic" inverse="true">
<key column="identifier" on-delete="cascade" />
<one-to-many class="CorreuElectronic"/>
</set>
<set name="telefons" inverse="true">
<key column="identifier" on-delete="cascade"/>
<one-to-many class="NumeroTelefon"/>
</set>
<set name="registraEvent" inverse="true">
<key column="identifier"/>
<one-to-many class="RegistreEvents" />
</set>
<set name="repEvent" inverse="true">
<key column="persona"/>
<one-to-many class="EventsComunicats" />
</set>
</class>
</hibernate-mapping>

Apparently there is some error with RegistreEvents class for in spite of my efforts I keep getting the sessionfactory error and the association references unmapped for this class gives me no message.

If you need further information just let me know; so DOES anyone have an idea how could I solve this? It's taking too long and I want to test my application.

Thanks in advance for your help.

Hi, I've realised that there is a misspelling in one of the classes. Here you have the good version:

public class RegistreEvents {
private int identifier;
private String subject;
private String body;
private modulInformacioEvents.RegistreEvents event;
private modulPersonal.DadesPersonals fromWho;
private java.util.Collection toWhom = new java.util.TreeSet();
...
}

I still get the error: I've tried many-to-many map for the relationship and I've tried it with composite-id when the present approach but the error still comes up.

what should i do? Please help.

public class RegistreEvents {
private int identifier;
private String subject;
private String body;
private modulInformacioEvents.Events event;
private modulPersonal.DadesPersonals fromWho;
private java.util.Collection toWhom = new java.util.TreeSet();
...
}


This problem with some unmapped reference is driving me crazy,

could you PLEASE help me?

Thanks a lot,
