Step 3: Create the Static Resources

1. Download this static resource .zip file: streaming_api_interactive_visualforce_demo-v40.zip

2. Extract the following files from the .zip fle:

   File Name	Description
   cometd.zip	Files for CometD version 3.1.0 and the Dojo toolkit used by demo.js. When you define a .zip archive file as a static resource, Visualforce can access the files in that archive. The .zip file becomes a virtual file system.
   demo.css	The CSS code that formats the Visualforce page.
   demo.js	The code used by the page to subscribe to the channel, receive and display the notifications, and unsubscribe from the channel.
   json2.js	The JavaScript library that contains the stringify and parse methods.
   StreamingApiDemo	The Visualforce page that displays the Streaming API notifications.

3. From Setup, enter Static Resources in the Quick Find box, then select Static Resources to add the extracted files with the following names:

   File Name	Static Resource Name
   cometd.zip	cometd_zip
   demo.css	demo_css
   demo.js	demo_js
   json2.js	json2_js
