I have a problem while using Hibernate bi-directional relationship.

My hbm file look like this:
-------------------------------------------------------
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="hibernate">
<class name="Submissions" table="submission">

<id name="submissionId" type="string" unsaved-value="null" >
<column name="submission_id" sql-type="raw(16)" not-null="true"/>
</id>

<property name="submissionNo">
<column name="submission_no" sql-type="VARCHAR2(5)" not-null="true"/>
</property>

<property name="createdTs">
<column name="created_ts" sql-type="Date" not-null="true"/>

<property name="lastModifiedTs">

</property>

...... ....... ........ ...... ...

<many-to-one name="application" insert="false" update="false" class="Application" column="application_id" />

</class>

</hibernate-mapping >

Application.hbm file

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

</property>

........ ...... ....... ....... .....

<set name="submissions" inverse="true" cascade="all-delete-orphan">
<key column="application_id"/>
<one-to-many class="Submissions"/>
</set>
</class>

------------------------------------------------------------------------------------------------------------
The problem I nedd to insert a record only into submission table using Hibernate.

My sample code looks like this:

SessionFactory sessionFactory=HibernateFactory.buildsessionFactory();
Session session= sessionFactory.openSession();
Transaction tx=HibernateFactory.begintransaction(session);
Submissions oSub=new Submissions();
// How will I set application id in Submission which has many-to-one relationship to application table
oSub.setSubmissionNo("0005");
oSub.setCreatedTs(new java.util.Date());
oSub.setLastModifiedTs(new Date());
session.saveOrUpdate(oSub);
HibernateFactory.commitTransaction(tx);
System.out.println("Done");
HibernateFactory.close(session);


How will I set application Id to submission table?

Please do favour with me

Thanks and regards,

When you specify insert="false" and update="false" in many-to-one element, you can include property element for the same column specified in many-to-one element. That means you have capability to set the value of application_id column using corresponding setter.



So now your code with slight modification is below



Below code gives you an idea how to persist both Application and Submission at the same time with a call to saveOrUpdate.

Thank u for ur reply. It is working fine.

Have a nice day,

Thanks and regards,
