Vineet,

Your browser is probably caching the session. May be during the testing you are using many different roles, users etc.

If you already tried closing the browser and clearing cache then try calling session_destroy() if you are in php or equivalent in flex. Call this at the top so the lccs session gets destroyed. Of course in production code you want to be smarter for performance reasons.

The simplest answer might be that your subscriber app isn't pointing at a

valid roomURL?

what do you mean by "account key" ? the username ? an external authentication token ?

also, did you try to run the sample app that ships with the SDK ? did that work for you ?

best thing to do is to collect the trace messages you get when running in debug mode in FlashBuilder and send them over. It's difficult for us to give you an answer without more details.

Hi Raff

             i login wid  https://collaboration.adobelivecycle.com/  that url and sign up for new developer after filling my details it provides me account details

like that:-

Accounturl:-https://collaboration.adobelivecycle.com/vineetosho

AcountShared Key:-6168f0942dd946bd9e5c14cfc98d7b31

RoomUrl:-https://collaboration.adobelivecycle.com/vineetosho/vineet...

so on the basis of that i can make my white board and screen shring component in using lccs.swz file.but when i share my screen and going to watch it on another application named(subscriber) it will show invalid instance error.it seems that this error is coming because of invalid AcountShared Key .

so should i create another shared with same roomUrl and sameAccount url or carry on with same shared key that i m using in publisher side.

hope u got my problem.please guide me how to resolve that invalid instance issue.i m totally confused,or plz provide me a little demo of screen sharing so tahta i can achieve it. i know i m too close.

Thanks and regards

Hi Vineet,

You shouldn't need to use any shared secret for running 2 apps - it's

specifically for external authentication. All you need is 2 applications,

both of whom have the same roomURL. One app can have the publisher, the

other can have the subscriber. I'd suggest you spend some time reading the

LCCS Developer Guide, or listening to the video tutorials we provide.

hope that helps

Hi Vineet,

Have a look at the "ScreenShareExample" in the sampleApps folder. Also,

please do read the developer guide. We're here to help, but there are limits

to how much we can do for you.

thanks and regards to you
