Apologies for taking so long to get back to you on your questions. To provide an app, JHS needs to have the script that implements the app loaded. This is done fro you automatically when you run studio demos. The other part of running an app is to load the page in your browser. This can be done by entering the URL and for something you'll do often you'll want to bookmark that URL.
Following is a sketch of what to do to run jdemo2 as an app called rollem: 1. copy the demo/jdemo2.ijs script to your app folder as rollem.ijs 2. edit rollem.ijs coclass to be rollem instead of jdemo2 3. start JHS and load the rollem.ijs script (you can automate this) 4. browse to page localhost:65001/rollem 5. bookmark that page to make it easier to run that app *** Look at the ~addons/ide/jhs/jijs.ijs script to see how it adds lines to include the codemirror javascript code. Add your jquery script load to the front of HBS definition in your app to make the jquery routines avaiable. With luck a JHS release the end of this week or early next week will include the jquery min scripts and an example of how they work. This will make it a bit easier to use jquery, but you can also roll your own right now.
