Question

I have a code which gets the date from Database from which I took year as below code:

 Date expiryDate=dataMgr.getDate(); 
 int validity=2;    
 expiryDate.setYear(expiryDate.getYear() + validity); 
 // some piece of code
 tx.commit();

i am using hibernate to fetch from Database. everything is working fine but the problem is after commiting ….The DB year from which i took the date (dataMgr.getDate()) also gets changed i dont know why ?? can some one clear me out???

For example, form the above code expiryDate:4/21/2012 (from Database). After commiting it gets changed to 4/21/2014 in DB which should not happen??
I haven’t used that corresponding object any where or updating any where ???

help me out

Answer 1

Objects are in Persistent state in a single transaction. Moreover, both expiryDate and dateMgr.getDate are referring to same object.

Instead of getting reference, get clone of object

Date expiryDate=dataMgr.getDate().clone();

I am not sure about the syntax, please check that.
