Hi have a problem with key-many-to-one. Please explain me if you know the solution.

My hbm files are:
1)

<key column="AUDIT_ID" />
<one-to-many class="com.dao.domainobjects.AuditParam"/>
</set>

</class>
</hibernate-mapping>

2)<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.dao.domainobjects">

</composite-id>

<property name="value">
<column name="VALUE" length="300" not-null="true" />
</property>

</class>
</hibernate-mapping>

when i have set the 2 values in the AuditParam. i am getting the following error.

Hibernate: select auditparam_.NAME, auditparam_.AUDIT_ID, auditparam_.VALUE as VALUE1_ from AUDIT_PARAM auditparam_ where auditparam_.NAME=? and auditparam_.AUDIT_ID=?

The answer is in your exception stack trace

Code:
Caused by: java.sql.BatchUpdateException: ORA-01400: cannot insert NULL into ("LEAF"."AUDIT_PARAM"."AUDIT_ID")


This means the AUDIT_ID parameter is not properly set in your code...
