FLex Login

Hi,
I am using logout in my flex project.At the time of login i
am creating one token.When i click logout i am deleting the
token.If i relogin with the same username and password old values
are not coming.

Hi,
I am using HTTP Services for login.I am creating one token
for authentication(token is present date).So,Everytime when user
logged in it ll generate a token with present time, an i am storing
that token in cache object.Once user logged in successfully ,if i
click logout button i am deleting the token.Up to this working
fine.If i relogin with the same username and password,I am able to
login successfuly now if i try to update some values ,this time
token is not generatded i.e its not calling login Service in .NET.
In mozilla everything is working fine.I am testing in
IE7.0.Its not working in IE 7
Did u understand my problem.

i have..
I will keep trying this stuff isn't cheap :)
I have tried about everything.. and can come up with zero..
This is why i have basically posted everything... even the
url of the data is shown...
What i really don't understand is why.. no matter what you do
the request_method always shows GET..
This is the current C source code...
It will just print out the env that the apache server is
getting..
#include <stdio.h>
int main(void)
printf("Content-type: text/plain\n\n");
char **envp;
/* print key=value pairs */
while (*envp != NULL) {
printf("%s\n", *envp++);
To view the data.. make a httpservice and set your debug to
stop once it catches the data...
Right now i have:

my breakpoint is set to line 13 of this code...
at the end of this function:
private function handleLogin(event:ResultEvent):void {
I use the debugger to look at the results...
when you run this.. aginst that C code.. the debugger will
show the environment of what has been called:
GATEWAY_INTERFACE=CGI/1.1
SERVER_PROTOCOL=HTTP/1.1
REQUEST_METHOD=GET
QUERY_STRING=
REQUEST_URI=/flex/cgi-bin/login.cgi
SCRIPT_NAME=/flex/cgi-bin/login.cgi
Notice the REQUEST_METOD is get...
If it is a get method the QUERY string should have some data
in it...
If you go to
http://genesis.dvrdns.org/flex/index.html
and type some junk on that screen you see different output...
GATEWAY_INTERFACE=CGI/1.1
SERVER_PROTOCOL=HTTP/1.1
REQUEST_METHOD=GET
QUERY_STRING=login=dfgsdgf&password=sdfgd&domain=asdf
REQUEST_URI=/flex/cgi-bin/login.cgi?login=dfgsdgf&password=sdfgd&domain=asdf
SCRIPT_NAME=/flex/cgi-bin/login.cgi
notice the query string.. and the REQUEST_METHOD
now if i change the HTML
to POST my "C" source code has to read from standard input...
and my Method should change to post...
but in this case.. since i am just printing the env values..
the POST in my html will have CGI print..
MET=post and QUERY_STRING will be empty..
Exmaple:
Here going to change
<form action="cgi-bin/login.cgi" method="GET">
Login: <input type="login" name="login"
size="10"><br>
Password: <input type="password" name="password"
size="10"><br>
GET to POST
<form action="cgi-bin/login.cgi" method="POST">
Login: <input type="login" name="login"
size="10"><br>
Password: <input type="password" name="password"
size="10"><br>
"index.html" 51 lines, 2700 characters
I am going to run the SAME app in debugger and via the html..
the html code will display the method as post and
query_string as empty which means data should come from standard
input..
html is as i expect:
SERVER_PROTOCOL=HTTP/1.1
REQUEST_METHOD=POST
QUERY_STRING=
REQUEST_URI=/flex/cgi-bin/login.cgi
SCRIPT_NAME=/flex/cgi-bin/login.cgi
Now going to set up debugger to run.. The REQUEST_METOD
should show POST and query string should be zero
REQUEST_METHOD=GET
QUERY_STRING=
REQUEST_URI=/flex/cgi-bin/login.cgi
SCRIPT_NAME=/flex/cgi-bin/login.cgi
as you see the METHOD from the debugger has not CHANGED
my network sniffer even shows my computer sending a request
of GET and not POST.. which is fine.. i can work with get...
but just the same.. the software isn't posting the data
correctly... if at all...
In my origional source code i use the get method in several
ways.....
printf(" <a
href="url://cgi.script?value&value&value">linkdata</a>
", value, value, value);
the cgi.script has to be a GET method for it to work in this
way..
but it isn't working.. the url request sent by this software
isn't sending it right for some reason...
I am really stuck until that works..

Looking for a Flex module to do Login, Registration, and License management

I'm looking for an open-source or commercial Adobe Flex module to do user Login, Registration, and License management. The back-end can be either on my site (PHP and MySQL) or secure 3'rd party site.
User Interface would have the following:
Register (new user)
Log-in (registered user)
Purchase a new license (logged-in user)
Apply the license to enable Flex app features (logged-in user)
Any suggestions are appreciated,
OutputLogic

I've seen Flex login components out there, but I'm pretty sure you'd end up customizing the heck out of them to work with your app and back-end server. It may be faster to look at some examples and roll your own to suit.
"purchasing a license" ... Take a look at PayPal's site for instructions on how to use their payment gateway in your app. It is pretty straightforward.
"enable Flex app features"... I would store the license information on the server, along with the user's account information. Then when they load the Flex app, a simple license check (during login) could enable certain protected views within the app.

Best way to handle login screen, transition to app

I've got a working app in flex (I'm an "advanced beginner")...and now want to add a login screen ahead of the app. My question is what is the best way to do so? My options I see are:
1. Login via HTTP screen: The is quick (no app load time), but not as pretty and harder to send parameters to the flex app.
2. Flex login screen using viewstates/stack: I could create a login page and upon successful authorization, I could switch the currentstate (view) or use a viewstack to show the application. This doesn't feel right - having the entire app in a viewstack or view state seems wrong somehow...
3. Flex login app which launches my main flex app: I have no idea if this is possible, but feel right. Quick load time to login, and no need to keep login app/screen in memory during main app execution.
Can someone share a "best practice" ?? Thanks

I'm not sure if it is best practice, but we are doing it as you described in #2. Our app isn't all that huge ( about 700k) and we decided we'd rather have the wait time while the app loads prior to login, rather than have them wait a long time after they submit their login. It is also nice for us to keep it all in one Flex project. Just thought I'd share what we are doing.

IS THIS POSSIBLE IN FLEX.

Looking at the error, it seems like you are not able to access the php file on the server.
Could you please try accessing the php from your browser directly and let us know if you are able to access it.
Thanks,

HTTPService redirect

I'm trying to use J2EE Servlet form based authentication by
posting to the well-known url j_security_check. In my web.xml file
I specify FORM authentication and my custom Flex login page. Upon
accessing a protected resource, I am redirected to my login page as
expected. Upon successful login the server sends an HTTP redirect
back to the protected resource, but I can't figure out how to
capture this redirect. My fault method will get called if I use the
wrong password, however the result method does not get called,
probably because it is a redirect. The server is actually
authenticating the user, because if I access the protected resource
again in the same session it works fine.
How can I get the HTTPService to follow a redirect, or at
least how can I get notification that the call has completed?
I'm using Tomcat in JBoss and the following code demonstrates
the problem, even without configuring web.xml.
Thanks,
Brian

waiting for reply.

there is already reply to your request in FlexBulder
category(even though not sure what flex builder has to do with it )
anyways, you cant get servlet to run unless you invoke it and you
are definitely not invoking it from flex .look at reply in
flexbuilder category.
it gives good example.

How to create a login session in flex?

Hi there,
I have a flex application with two states. One is a "login" state which is a screen with username and password. The other state is "loggedIn" state which is a screen with a small application. As soon as the user credentials are checked from the back end, based on it's success, I'm changing the state to "loggedIn", else there is a message to the user about login failure in "login" state itself.
My problem is if I'm in "loggedIn" state and if I hit refresh button of the webpage(F5), it goes back to the login screen i.e., it just restarts the application..
How can I control this? Is there something like login session which can do the trick?
Appreciate your help...

Flex 3.0 Login Script

Hello,
I found, what seems to be a nice login application for Flex.
However, something is wrong and it is not working. I have check,
and recheck the code over and over again and I can't seem to find
what is wrong. I am using Flex 3.0, PHP and a MySQL database.
Everything appears good with the PHP script, however, the web page
just looks at me and does not change to the page that it should.
There is a message in the browser that it is transfering data from
the database, but it doesn't display. The "Alert" message doesn't
show either if I put in the wrong username and password.
Can someone help me with this?
Thanks,
(See Code Below)

Hi,
Please check if the result event is getting fired. Add a
break point in the checkLogin function and debug the result object.
Or just add a else block in the checkLogin function, my guess is
that the if conditions are failing and so you are not seeing any
changes. To be on the safe side, do add a handler for the fault
event of the HTTPService.
Hope this helps.

Login security in flex with Java

Hi ,
I am looking for login secruity with session in flex.
Thanks,
Alok

If you want to use Java as the back end, you have BlazeDS and
LiveCycle Data services to make your programming simpler. BlazeDS
and LCDS will allow you to invoke the Java classes from the Flex
application. For more details on BlazeDS and LCDS visit the URLs

Flex/Air Application Login - the best way

Hi,
I have small ideological problem :) I have login form in my
application. So, each user has his own login and password. As
serverside is used LCDS with secured destinations.
And here are two possible approaches:
1) I use server side auth. mechanism (Tomcat realm) to check
users credentials. I have custom auth. class, which check user
credentials. This works, but, i have some problems in logout
operation and if user enter wrong username or password.
2) Second way is this. I have only one user (which is
hardcoded in app or loaded from config). This user is authenticated
to server at the start (setCredentials() ). I need this, because
all destinations are secured. And the "real user" is verified
against the services that will bring the information if that user
is verified or not.
So, i don't know which approach is better. Now, using the
first.
What do You think about this ? Which way is the best ?

Hi,
this topic can be deleted (i can't do this, i can edit, but
can't delete this post).
I'm very sorry, i wanted to post my question into Flex Data
Services forum, not here.
