Simple Remote Shared Object with Red5 Flash Server
- by John Russell
Hello,
I am trying to create a simple chat client using the red5 media server, but I seem to be having a slight hiccup. I am creating a shared object on the server side, and it seems to be creating it successfully. However, when I make changes to the object via the client (type a message), the SYNC event fires, but the content within the shared object remains empty. I suspect I am doing something wrong on the java end, any advice?
Console Results:
Success!
Server Message: clear
Server Message: [object Object]
Local message: asdf
Server Message: change
Server Message: [object Object]
Local message: fdsa
Server Message: change
Server Message: [object Object]
Local message: fewa
Server Message: change
Server Message: [object Object]
