Hi all, first I am new using hibernte so maybe you may excuse my stupid guestion...
I try to use a one-to-many collection between the following classes:
ScaleGroups.hbm.xml
Code:
<?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>
<class
name="com.hoellehuettner.persistence.ScaleGroups"
table="T_SCALEGROUPS"
>
<id
name="IDScaleGroup"
column="IDSCALEGROUP"
type="integer"
>
<generator class="native">
</generator>
</id>
<set name="Scales" lazy="true">
<key column="IDSCALEGROUP" />
<one-to-many class="com.hoellehuettner.persistence.Scales" />
</set>
</class>
</hibernate-mapping>
Scales.hbm.xmlCode:
<?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>
<class name="com.hoellehuettner.persistence.Scales" table="T_SCALES">
<id name="IDScale" column="IDSCALE" type="integer">
<generator class="native">
</generator>
</id>
<property name="IDScaleGroup" type="integer">
<column name="IDSCALEGROUP" not-null="true" unique="false"/>
</property>
<property name="name" type="string">
<column name="SC_NAME" not-null="true" unique="true"/>
</property>
</class>
</hibernate-mapping>
Code:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.datasource">java:comp/env/jdbc/HSP</property>
<property name="show_sql">true</property>

Should look like a simple sample but invoking the servlet on my apache I get a servlet exception. This only occurs while using the one-to-many relation from ScaleGroup 2 Scales. Normal field mapping or one-to-one mapping seems fine.
Thx in advance for your help.
