jdbc

i have a date field in my database and two other date fields which are dependent on the first.
i have to calculate two dates using the first input date.
i have to calculate date after 3 months and 6 months.
i have used servlets as mediator.
i have used inbuilt functions like months after,and date+90(for three months)
eg:
if the user input 12-01-2001
i have to calculate 12-4-2001 and 12-7-2001
and insert in to table.
but i could not do it from the servlet.
can any one help in concern??

What is the error
It may be due to database you are using
Usually databases expect date to be in their default format like in oracle 12-JAN-2001
So if you try to put the date in other formats it may give error
I hope I am right, may be there may be other causes for the error

i am not getting any error but the values are not getting updated.
i am using Access 2000

I dont think there should be any problem. You just add the date fields with required number of months,and insert into the database.I think the error is in the database.
By the way what error you are getting.Is there any problem in database connetivity

Check out the database format for the date in Access which you have specified
Access default format is I believe dd/mm/yy make
If you specify it as short date it may accept
Best thing would to debug would be to c&p the query you are executing in servlet in MS-Access query window and execute it
It would allow you to find whether the query is correct
There will be some sqlexception thrown in the webserver prompt
