Dear jsp expert,
I would like to continue this discussion but with abit lower issue since I'm
a JSP beginner. I use Tomcat 4.1 and J2SDK 1.4.2

I made 3 basic pages:
1. login page where user can submit his username and pwd
2. validation page to validate username and pwd from database, I set the
session attribute here
3. index page where is the main page, I tried to get the session attribute
here

When user has been validated at the validation page,
I then forward it to index page.
But I always got this at the index page:
"org.apache.jasper.JasperException: Error: Attempt to clear a buffer that's
already been flushed"

No matter what method I use to set and get the session attribute, that error
always appear. I believe there must be a solution for this as it is a very
common practise. Any suggestion maybe? Thank you in advance..


Regards,
Pius

That is because that page is not reloading and the html has already been
created. It can be countered by adding a refresh whenever the page returns
due to the back button.

What i mean to say is
Check if the page is opened by back button , if it is so then refresh the
page then all the variables get resend ..
and you can check if it is null.
