The swfobject.js is a popular way of embedding Flash content to web pages recommended for example by YouTube. Now this integration is available as a GWT-based Java API as well as a server-side API for Vaadin. If you want to use the swfobject.js API from a GWT component you only need to use static functions in the SWFObjectJSNI class. For normal Vaadin use consider using the SWFComponent. This add-on Includes swfobject.js version 2.2. Note: SWFObject requires also the Widget RPC add-on.
