Hi all, I think it has been asked before but I don't recall any answer as this is: 1. Not a Flex directly related issue, 2. Not even a BlazeDS issue per se,
My client-server application depends on a Flex client and a Tomcat + BlazeDS + MySQL + Hibernate backend server. It tracks whether a user is logged in by keeping a "InSession" boolean field in the database. This "InSession" starts the session clock by the time the user has properly logged in and stops by the time he has properly logged out by "Exit" the app. Then the database is updated and that user is marked as "InSession=false", while that session has been timed. But if the communication channel goes down (Internet, LAN, etc), or the client's browser is inadvertently force closed, the database loses track/sync of the user and keeps reporting as "InSession=true", while session time keeps running indefinately. What I need is a server side procedure that: 1. Either catch an exception on losing connection event, or 2. in a continuous loop scans for connected users (out of a list of "InSession=true") Obviously losing the client-server connection is a very generalized problem to track and needs more specific solutions. I am not sure if this can be solved in BlazeDS level, or I have to go to WEB server sockets. But may I ask if anyone has a suggestion, or some relevant documentation for me to study? Thanks all George
