I am getting the above exception on a primary key field of a class.
Could anybody throw some light what might be the reason?..



I have the Class properly coded with the <Identifier>Primary Key and also the mapping does not have any problem...
The mapping is as follows:

<hibernate-mapping>

<class name="com.refapp.bo.IPAbstract" table="INTD_PARTY">
<cache usage="nonstrict-read-write" />

<id name="id" column="INTD_PARTY_ID">
<generator class="sequence">
<param name="sequence">SEQ_INTED_PARTY_ID</param>
</generator>
</id>

<property name="name" column="LAST_NM" />

<set name="ipAddresses">
<key column="INTD_PARTY_ID"/>
<one-to-many class="com.refapp.bo.IPAddress" />
</set>

<joined-subclass name="com.refapp.bo.EmployerIP"
table="EMPLR">
<key column="INTD_PARTY_ID" />
<property name="employerAcctNo" column="EMPLR_ACCT_NBR" />
<many-to-one name="orgType"
class="com.refapp.bo.OrganizationType" column="ORGN_TYP_CD" />
</joined-subclass>

<joined-subclass name="com.refapp.bo.WorkerIP" table="WORKER">
<key column="INTD_PARTY_ID" />
</joined-subclass>

</class>

</hibernate-mapping>

The problem is resolved as it was else where in the maping.
I had a mapping for Address.hbm.xml file, that was responsible for the error.

Old map:
<hibernate-mapping package="com.refapp.bo">
<class name="IPAddress" table="INTD_PARTY_ADR">
<cache usage="nonstrict-read-write" />
<composite-id name="id" class="IPAddressId">
<key-property name="interestedParty" column="INTD_PARTY_ID" />
<key-property name="address" column="ADR_ID"/>
</composite-id>
<property name="effectiveDate" column="EFFV_DT" />
<property name="endDate" column="END_DT" />
</class>
</hibernate-mapping>
New Mapping:
<hibernate-mapping package="com.refapp.bo">
<class name="IPAddress" table="INTD_PARTY_ADR">
<cache usage="nonstrict-read-write" />
<composite-id name="id" class="IPAddressId">
<key-property name="interestedParty" column="INTD_PARTY_ID" type="long" />
<key-property name="address" column="ADR_ID" type="long"/>
</composite-id>
<property name="effectiveDate" column="EFFV_DT" />
<property name="endDate" column="END_DT" />
</class>
</hibernate-mapping>


But then i am getting a new error now:

java.lang.ClassCastException

So could anyone throw some light on it?
Pls..
