RelaDetails relaD = (RelaDetails) tmpTable.get(RowId);
if (relaD!=null){
String abc= relaD.getObj1();
out.println(abc);
}
Should 'abc' ABOVE be String?
I am sure that the key is exist, but I didnt get anything for variable abc.
Thanks a lot
Best Regards,
Howard

u can retrive data from Rowld key
what u do is
RelaDetails r = (RelaDetails) tmpTable.get(Rowld);
if( r==null) it means there is no such a key.
otherwise everything is in r.
