I'm new to the ArcGIS JavaScript API and I'm trying to set up a local development environment for a web application. I'm having trouble with getting on of the example scripts provided by Esri to load correctly when opened locally (Code 1 below). This code retrieves a map service hosted in ArcGIS Online added to the application. I need to be able to retrieve a map service created in ArcGIS Online into an application i want to build, but when I tested this out using Esri's example script locally on my machine, I get an error (Error 1 below).
I have Tomcat 7 running locally on my machine, listening on port 80 with the service started. I believe its not a configuration or firewall issue since I am able to load another of the example scripts just fine (Code 2 below). Due to the fact that Chrome's console logged an error for the init function in Code 1, I think the issue lies with something happening in this function.
Why may this be happening?

Your first app is attempting to load the web map from a file:// uri (see the Chrome console error: "Unable to load file://www.arcgis.com/sharing/...") and not http (or https) as it should.
Make sure you are hosting the html in a page served out by your web server and not just double clicking it to open directly from the file system.
