Hi,
You can run the given Flash demo by copying the "LS_HOME/DOCS-SDKs/sdk_client_flash_flex(js_bridge)/examples/FlashStockList/deploy" folder to "LS_HOME/pages".
This demo will be accessible from Lightstreamer's internal web server. Assuming you are running the server with the default configuration, go to
http://localhost:8080/deploy to see the demo.
Let me know if you need further details.
