RE: preventing user from validating twice
You can use savetoken(request) method for generating a token (when loading the
screen)and
Cheque for the existence of token using istokenvalid(request) method for ensuring that
you do not submit same data again.
Code in action wld be like
isTokenValid(request)
{
...
DB insert
}
Thanks,
Satish

Subject: preventing user from validating twice
Hi,
i think it must be a FAQ, but i did not found anything on
this issue.
When my user submits a form, the action executes an SQL
Insert in the DBMS.
What happened is that when user click twice, the second
inserts fails with SQLException.
What is strange, is that i cannot reproduce it in WSAD, but
it happens on a full Websphere.
Is there a way i can know that a user already submitted a
form ?
