Hi guys,

I got 2 persistent class, which is one-to-many(PostingIdentification.java) and many-to-one (ClassifiedItem.java). I tried to implement to hashCode() and toString() and equal() using Commonclipse. After that when I tried to do a query like follows:

* @hibernate.query name="PostingListByAmount"
* query="select pid from PostingIdentification pid join pid.classifiedItem classitem where classitem.amount <= ?"
*


then I got the stack trace. But after removing the hashCode(), toString and equal(), the problem gone. Please help, Thanks !

rgrds,
