I am getting an error mapping composite keys. Please advise. Mapping files are below.

Hibernate version:
Version 2
Mapping documents:

I have one table
<hibernate-mapping package="com.xxx.business.domain">
<class
name="PlanPkgOptionValue"
table="PLAN_PKG_OPTION_VALUE"
>
<composite-id name="id" class="PlanPkgOptionValuePK">
<key-many-to-one
name="planPkgOption"
class="PlanPkgOption"
>
<column name="PLAN_PACKAGE_ID"/>
<column name="OPTION_VALUE_ID"/>
</key-many-to-one>
<key-many-to-one
name="optionValue"
class="OptionValue"
column="OPTION_VALUE_ID"
/>
</composite-id>

and another related table
<hibernate-mapping package="com.xxx.business.domain">
<class
name="PlanPkgOdometerOptVal"
table="PLAN_PKG_ODOMETER_OPT_VAL"
>
<composite-id>
<key-many-to-one name="optionValue" class="PlanPkgOptionValue">
<column name="OPTION_VALUE_ID"/>
<column name="PLAN_PACKAGE_ID"/>
<column name="OPTION_ID"/>
</key-many-to-one>
<key-many-to-one
name="odometer"
class="PlanPkgOdometer"
column="ODOMETER_ID"
/>
</composite-id>
