How to get Login page while submitting a data form

[Sanjaya Kumar Patel]

Hi All,

My requirement is this:

1. User fills a form and submits.
2. If he has not logged in, login form comes up.
3. after logging in, the data automatically gets submitted and next page comes.

I am new to struts and unable to figure out the natural solution, even after a lot of googling. As I understand step 2 should be easy using interceptor, but how to get step 3 work?

I am using struts 2.1.8.

thanks,
Sanjay

Hi Sanjay,
when intercepting action for the first time (no logged user),
You can save submited data along with request uri and put it into
session/database
then after login (inside login action), check if these informations
are present in sesion/database
and forward to desired action with all the params that You have
collected before login.

Best greetings,
Paweł Wielgus.

Hi Pawel, Thanks for the insight. I would give a try.


Being a common scenario, is there any existing work already present for
this, so that I don't have to reinvent the wheel? I guess there should
already be some established library / code sample which people follow.
What do people normally do?

If a <form> requires authentication, don't render it until the
user is logged in.

If you are worried about the user's session timing out before
the form is submitted, implement some sort of javascript timer
that (after a period equal to a session timeout), pops up a
modal login form.  Successfully submitting the login form
Resets the timer, makes the login form disappear, and
the user is free to submit their form.

Nice idea!



Curious to know what is the common practice. Would like to hear if people are using some established libraries or pattern etc.

+1.

Sanjaya, Spring Security will remember which URL user was trying to access
before the login and will replay that URL after successful login .
However, I'm not aware of Spring Security ability to replay POST data from
a form.

Hope that helps.

Dale, Harun, Thanks a lot for the direction.

I saw ACEGI a bit and then am thinking to first try writing own interceptor - basically extending the suggestion in the book "Apache Struts 2 Web 2.0 Projects." Will post the code once successful.

thanks,
Sanjay

For security this is pretty much always a mistake.  You don't want bugs
in your security implementation, and the best way to avoid them is to
use a library that has been extensively tested by others.
