Hi, i'm new with Hibernate and want to use a existing datamodel in Hibernate


Tabel: ST (ID = Primary Key)
--------
ID

Table: DD (ST_ID + NUMBER = Primary Key)
---------
ST_ID
NUMBER


Table: VALUE (ST_ID + DD_NUMBER + ROWNR = Primary Key)
---------
ST_ID
DD_NUMBER
ROWNR


Relation: ST one-many DD one-many VALUE

In my domain

Class StamTable
long id;
Set<DataDictionary> dds;

Class DataDictionary
long st_id;
long number;
Set<RowValue> rowvalues;

Class RowValue
int rownr
String value;


Now i want to map it with a set and composite like this

<class name="StamTable" table="ST" >
<id name="id"><generator class="sequence"/></id>
<set name="dds" table="DD">
<key column="ST_ID">
<composite-element class="DataDictionary">
<property name="number" not-null="true" />
</composite-element >
</class>

<class name="DataDictionary" table="DD">
<composite-id>
<key-property name="st_id" />
<key-property name="number" />
</composite-id>

<set name="rowvalues" table="VALUE">
<key>
<column name="ST_ID">
<column name="DD_NUMBER">
</key>

<composite-element class="RowValue">
<property name="rownr" not-null="true" />
</composite-element >
</class>

When i now make a StamTable, DataDictionary and RowValue object and save only the StamTable only a ST record and DD record get's inserted, not a VALUE record.

What can i do?
