Hallo,

I have a class Person with the sets Address and CommunicationInfo. If I save a Person, I get just UPDATEs for the sets instead of INSERTS:

INFO: schema export complete
Hibernate: select hibernate_sequence.nextval from dual
Hibernate: insert into Person (Client, Surname, Maidenname, Forename, Title, Martialstatus, Religion, Birthday, Placeofbirth, Socialsecuritynumber, Spokenlanguages, "Comment", id) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: update CommunicationInfo set client=?, "Comment"=?, ConnectionType=?, Connection=? where id=?
Hibernate: update Address set id=? where id=?
Hibernate: update Address set id=? where id=?

The Person.hbm.xml file is:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping
package="ena.bl">

<class name="Person" table="Person">
<id name="id">
<generator class="native"/>
</id>
<property name="Client"/>

<property name="Surname"/>
<property name="Maidenname"/>
<property name="Forename"/>
<property name="Title"/>
<property name="Martialstatus"/>
<property name="Religion"/>
<property name="Birthday"/>
<property name="Placeofbirth"/>
<property name="Socialsecuritynumber"/>
<property name="Spokenlanguages"/>
<property name="Comment" column="`COMMENT`"/>

<set
name="Address">
<key column="owner_id"/>
<one-to-many class="ena.bl.Address"/>
</set>

<set
name="CommunicationInfo"
<key column="owner_id"/>
<one-to-many class="ena.bl.CommunicationInfo"/>
</set>



</class>

</hibernate-mapping>


Any help? Thank you!

Richard

eh - if the address can be updated it must have been inserted previously!
(and you don't show what code you are actually executing)

this stuff is described in many tutorials, the docs and examples - take one of those and see that work and work out from there ;)

Max, that is what I try. However, I’m a little bit confused with the one-to-many mappings. It doesn’t what I want. Now I have a problem with “cascade”. If I save a Person l, the collections aren’t saved. I got a duplicate key error for the 2nd address.

l.setForename("Lucky");
l.setSurname("Luke");

Ci.setComment("bla bla ");
Adr1.setCity("Braunschweig");
Adr2.setCity("Hildesheim");

l.addAddress(Adr1);
l.addAddress(Adr2);
l.addCommunicationInfo(Ci);

// with this three lines it's working ...
//s.save(Adr1);
//s.save(Adr2);
//s.save(Ci);
s.save(l);

Here the hbm.xml file:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<property name="Title"/>
<property name="Martialstatus"/>
<property name="Religion"/>
<property name="Birthday"/>
<property name="Placeofbirth"/>
<property name="Socialsecuritynumber"/>
<property name="Spokenlanguages"/>
<property name="Comment" column="`Comment`"/>

<set
name="Address"
cascade="all">
<key column="owner_id"/>
<one-to-many class="ena.bl.Address"/>
</set>

<set
name="CommunicationInfo"
cascade="all">
<key column="owner_id"/>
<one-to-many class="ena.bl.CommunicationInfo"/>
</set>

</class>

</hibernate-mapping>

What is missing that hibernate gives the addresses a new id? Must I write something in the mapping file for the address class? Thank you! (It must be very easy … But I can’t see the forest because of the trees.

Richard

does you address know it's Person ?

if yes - then remember to set inverse to false|true the right places (read docs about inverse if you don't know about it ;)

No, neither my Java-Address-Code nor my Address-mapping file know anything about Person. Just the Person knows about the Addresses.
How can I introduce the Person to the Addresses? Thank you!

Regards Richard

i really can't come up with better explanations than already said and done in faqs, examples, dcos etc.

Please take one of those and follow - and see it work!
