Hi everyone,

I am using the SchemaExport tool with the following mapping:

<hibernate-mapping package="com.frs.model">
<class name="CustomerAttribute" table="customer_attribute">
<composite-id
name="customer_attribute_pk"
unsaved-value="none">
<key-property name="customerId" type="integer" column="customer_id"/>
<key-property name="name" column="name" type="string" length="256"/>
<key-property name="value" column="value" type="string" length="256"/>
</composite-id>

<property
column="create_dt"
name="createDt"
not-null="true"
type="date"
/>

<many-to-one name="customer" class="Customer" column="customer_id" foreign-key="customer__id_fk1"/>
</class>
</hibernate-mapping>


I recieve the following error when I run the SchemaExport tool:

net.sf.hibernate.PropertyNotFoundException: field not found: customer_attribute_pk
at net.sf.hibernate.property.DirectPropertyAccessor.getField(DirectPropertyAccessor.java:74)
at net.sf.hibernate.property.DirectPropertyAccessor.getField(DirectPropertyAccessor.java:80)

Seems the tool is looking for the composite-id class, which I do not want to define since it generates an unnecessary class. Anyway to get around this?

i.e. if I edit the composite key to:

<composite-id
name="customer_attribute_pk"
unsaved-value="none"
class="something">
<key-property name="customerId" type="integer" column="customer_id"/>
<key-property name="name" column="name" type="string" length="256"/>
<key-property name="value" column="value" type="string" length="256"/>
</composite-id>

The error goes away.

Thanks!

Scott.

I'am sorry . I've find the way to do what I want.

sorry , I've post error.

I also want to know that...

It seems hbm2ddl can't work without PK class.

have you find the way to do that?
