Hi,

I am new to hibernate and have a below requirement:

I have an object of ProductJSPBean mapped to a different table in DealJSPBean object.

Everytime I save DealJSPBean which has the same primary key and holds a reference to ProductJSPBean in trade_id column
which is an autogenerated key, it alwyas inserts a new row in eb_product_data.

As a result, I end up having multiple entries everytime I save DealJSPBean object.

I have tried to find the answer through various blogs and forums but nothing seems to work for me. I am stuck now.

Any kind of help, will be appreciated.

My DealJSPBean.hbm.xml looks like below:

<hibernate-mapping package="com.jpmorgan.eragbat.eblotter.jsp">

<class name="DealJSPBean" table="eb_deal_data">
<id name="dealId" column="id">
<generator class="assigned" />
</id>
<property name="appropriateness" column="appness" />
<property name="lastModifiedDate" column="last_modified_date"
type="date" />
<many-to-one name="productJSPBean" class="ProductJSPBean"
column="trade_id" not-null="true" cascade="save-update,delete" unique="true" />
</class>
<!-- ProductJSPBean.hbm.xml -->
<class abstract="true" name="ProductJSPBean" table="eb_product_data">
<id name="id" column="trade_id">
<generator class="identity" />
</id> <property name="swapswireEligible" column="is_swapswire_eligible" />
<property name="mkNetINPV" column="gross_inpv" /> </class>
</hibernate-mapping>
