you can put the previous added lateExtraAmount into session.
After that, just retrieve it back from the session n do ur calculation.

hi,
iam using struts, i have one class i.e LateExtra,in this class
i have wriiten the code like below
double lateExtraAmount = calc.calculateLateExtra(currentContract);
from the above iam getting the lateExtraAmount
for ex:intially the amount is 2000 After that i Updated the amount to
2500,
then the lateExtraAmount =Updated Amount-Intial amount i.e 500,
then After that iam setting the value as
model.setAmount(String.valueOf(lateExtraAmount));
After some time I updated the amount from 2500 to 2600 then
lateExtraAmount=Updated Amount-Intial amount i.e 100.
but i want the previous added lateExtraAmount and Latest added
lateExtraAmount .for that i have wriiten the code like below
String newLateExtraAmount=new Double(Double.parseDouble(model.getAmount
())+lateExtraAmount).toString().
model.setAmount(String.valueOf(newLateExtraAmount));
but the problem with the above code is whenever iam going to that
screen the amount is incrementing.
my problem is there anyway to store the previous added lateExtraAmount?
so that i can add the previous added lateExtraAmount with Latest added
lateExtraAmount.i will get the result properly
if anybody knows please assist me i have been trying from the last two
days...
thanks,
prasad
