Iam working/designing portlets, which uses Flex Actionscript for scripting on the UI, and uses LiveCycle Dataservices to connect Remote Objects.

now this LiveCycleDS is a J2EE app, which is residing on app. server
How reliable is this design, with respect to Clustering, and session for a authorized user?

Any one used Flex portlets please shed some light.

there are many resources on IBM, but there is none with this combination.

Thank you
