RE: [flexcoders] Authentication with Macromedia Flex
Hi
Dimitrios,
From
reading through your earlierposts I get the impression that you are using
a two methods to authenticate users. Initially, you authenticate the user using
standard J2EE form based authentication. Then when using a service if you
receive an authentication fault you use a flex popup window to re authenticate.
Is this correct?
Also,
if you get a session time out do you resubmit the original service request after
re-authentication? If so, what is the best way to generically resubmit the
request?
Regards,
Allister

I put theh handling of the
failed authentication directly in the Services.mxml... simple and
works.
mx:Script
function
handleRemoteFault( event ):Void {
if(
event.fault.faultcode == "Client.Authentication" || event.fault.faultcode ==
"401" ) {
// do whatever you want here, its a free
country
}
else
{
event.call.faultHandler( event );
}
}

flexcoders@yahoogroups.comSubject: Re: [flexcoders] Authentication

so, I got auth working using the approach you
mentionedCallbackHandler handler = new SimpleCallbackHandler( userName, password
); Subject subject = Authentication.login( handler
); ServletAuthentication.runAs( subject, httpRequest
);silightly different looking under JRun of course. Now, I'm
horribly stuck on getting the roles of the user after logging in. I have
set up Roles under teh JMC, JRuns instance manager. I tested it all with
BASIC auth, so I know the autentication and authorisation are working.
I've been working all week on getting the roles for the user after
authenticating and can't find squat of an example. Any hints
perhaps?On a similar note... Using service.setUserNamePassword()
in Flex I know it will authenticate a user, does it also authorise the user by
gathering up the roles defined in the containers JAAS config?and one
more concerning cairingrom to use service.setUserNamePassword() effectively, it appears you would
need to modify the onfault event of a service in services.mxml file to check for
a failed authentication. If not here then every command using the service
would need this check, eh? What other way can this be done possibly?
Create a AuthCommand abstract class to extend or
something?DK

Where did you hear that it was not the approach to

Yes, when you user source="servlet", you must configure
the source attribute in the remote-objects section of the flex-config.xml.
You have to set it to the name of your context. So if your web application
context is "localhost:8080/batman", then you must set:
sourcebatman/source
or for no security at all (don't do this in
production):
source*/source

I was under the impression this was not the approach to take in
1.5. IIRC, when messing with source= "servlet" I had to add some info to the flex.config
file. Can you comment on this? Just curious as there seems to be
so many ways to do this. DK

Ok here is how to do this.
Basically you will have a login.jsp page that will

[flexcoders] Re: Remote Objects in Flex 1.5 Problem
Hi Graham, Thanks for the reply. It helped solve some follow up issues after I overcame the below problem. The cause of this problem was the fact that the action script class representing the java object was never specifically referenced in the action script code because arrays were being passed back and then being set on the Model object (ie no casting was needed). Once the VO Action Script class was imported into the command class then everything started working as per normal. Now in hindsight this makes sense because if there is no direct reference to the VO then flash never loads the class, therefore the Object.registerClass is never performed meaning no link exists between the VO and Java Object. If there is no link then when the object gets past back to a Remote Object flex server treats it like a ASObject rather than the required Java Object. This question is related to your reply. Is there some way of telling flex server not to pass final Static fields from Java to Flash? I have worked out how to do it from flash to Java using _global.ASSetPropFlags, but I would prefer that they are not sent to flash to start with. Thanks Again, Allister --- In flexcoders@yahoogroups.com, Graham, Jason [EMAIL PROTECTED] wrote: You have something in your class that the serialization layer is having a problem with. Make sure in your class you don't have any static final fields. This will cause a problem because the serialization layer going from java to flex sends these fields across, when you send the object back to java it blows up trying to set those fields. -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of allister_dickson Sent: Friday, February 24, 2006 12:16 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Remote Objects in Flex 1.5 Problem I am integrating a Flex frontend with a J2EE backend using Cairngorm Framework and RemoteObjects.
