Hi Friends please help me. I am getting strange issue.

cityBean is parent class and RvBoardingPointM is child table.
one-to-many mapping between cityBean and RvBoardingPointM .

Following code is for saving parent and child records.

RvCityM cityBean = new RvCityM();
cityBean.setName("Testing");
cityBean.setCreatedDate(new Date());
cityBean.setStatus('A');

Set<RvBoardingPointM> points = new HashSet<RvBoardingPointM>();
RvBoardingPointM point1 = new RvBoardingPointM();
point1.setName("Test1");
point1.setRvCityM(cityBean);

RvBoardingPointM point2 = new RvBoardingPointM();
point2.setName("Test1");
point2.setRvCityM(cityBean);

List list = boardingTable.getData();

cityBean.setRvBoardingPointMs(points);


Session session = getSession();
Transaction transaction = session.beginTransaction();
try{
getHibernateTemplate().saveOrUpdate(cityBean);
getHibernateTemplate().saveOrUpdateAll(points);
transaction.commit();
}catch(Exception e){
transaction.rollback();
throw e;
}


the above code is successfully saving records. I can able to see the records from backend.

Strange thing is that, if I redeploy the code, child records are removing on server startup, but parent records are remain.

Please help me on this.
