Dear ALl,

I am a newbie. I am struck with a very basic doubt in Hibernate,



Let say we have two entities – Customer and Account. Customer can have multiple accounts. Also, in two entities, we have bidirectional association.



Now, given customerId, I can fetch customer and then accounts.



Now, because association is bidirectional, we should be able to fetch account and then its customer, if accountId is given. Somehow, I am getting strange error in Hibernate, when I say that –

accountDao().load(accountId). I don’t see any issue in this.



Error is –

01:01:44,590 ERROR [LogInterceptor] EJBException in method: public abstract org.infy.enr.infybank.vo.AccountVO org.infy.enr.infybank.service.ejb.UserService.getAccountDetails(java.lang.Long), causedBy:
