Hi Wei,

please try to post questions in the right forum section.

Anyway, I'm not sure I've understood the situation.

If the problem is that the demo works under Lightstreamer internal web server but don't if you deploy the pages under an external web server take a look to this thread: http://www.lightstreamer.com/vb/show...ghlight=Domain

Otherwise can you see any javascript errors when running the application?

Is your application tree like the one below?

-DojoDemo <- files from LS_Dojo.zip
|---LS <- files from LS_HOME/DOCS-SDKs/sdk_client_web/lib/
|---Dojo <- files from Dojo's distribution zip (e.g. dojo-0.4.0-ajax.zip)
