<!DOCTYPE hibernate-mapping PUBLIC	"-//Hibernate/Hibernate Mapping DTD 3.0//EN"

		    <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,
Sreekanth
