Maybe any J2ee gurus can comment better, but here are my 2 cents. Regarding point 2,
Flex is a client side technology, while session management and clustering are server side concerns. Is it not all about appending a session id as one of the parameters in the remote call for the calling client. Whenever some data is committed in a session, it is the server's duty to persist it isn't it? Flex would report you an error in case a remote call would fail, in case your server -1 is down. You can set a retry call in your code after a definite interval to check if the server 2 is up and then you receive a proper response. I dont think the usage of LCDS would depend on this, it is just a going to serialize the flex call to java call and vice-versa. It is required when you directly need to invoke a server side java method. ~Peeyush On Mon, Mar 31, 2008 at 8:01 AM, olegkon <[EMAIL PROTECTED]> wrote: > Hi, > > I just started a new job.
