Hi,
I am peristing data into single table in oracle.. I am not using sequence at all. I am using hibernate increment in hbm file.

public class TestLwot {


 public static void main(String[] args) {
 MakeLwotObj makeLwotObj= new MakeLwotObj ();
 LWOTDao lwotDao = new LWOTDaoImpl();
 lwotDao.persistLWOTPatient(makeLwotObj.getLwot()); // IT CALLS SAVE OR UPDATE OF HIBERNATE
// makeLwotObj.getLwot() returns LwotObject.. which does not contain any id.. id field is null..

 try {
 Thread.sleep(30 * 1000);
 lwotDao.persistLWOTPatient(makeLwotObj.getLwot()); // IT CALLS SAVE OR UPDATE OF HIBERNATE

 } catch (InterruptedException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }

 }


}

I am trying to run the SAVEORUPDATE using 2 jvm's then its failing with en exception stating that

ORA-00001: unique constraint (DATEAM.SYS_C0039965) violated

Does any body has any ideas why it is doing that






You get this problem when u run this code from different system's or through Different JVM's.

Thanks
