Submit Button multiple click issue

[Brill2]

Hello Guru's,
Do not know if I am posting in the right place and please let me know
if it is not. I have an issue with an application that I am building
that uses JSP and SERVLETS. Basically when someone clicks the submit
button more than once their record gets saved twice in the database.
I'm sure this issue has been adressed before but what I have seen to
date is people recommending disabling the submit button.

I don't want to do something client side which might potentially take
away functionality from the user. What I would like to know if there
is anything in the HttpServletRequest or HttpRequest objects that might
be able to help me identify if the user clicked the submit button
twice.

Any ideas out there?

Greatly appreciate your thoughts,
Regards,
Dave

Hi
you may do onething to resolve the problem.i.e first of all u have
to check whether there is any duplicate and insert only if there is no
duplicate.

Hi
u can do this also. i.e u can pass some value to the function that
is called on the onclick event and check for the same in the function
and call the servlet accordingly.use javascript for this.
