In Monaca, I installed JQuery using File | Manage JS/CSS components... Added the JQuery (Monaca version) 2.03 Pressed save, and don't see the JQuery file(s) in my project.
Where are they?
OK I found it: You have to click the settings thingy in the project, and above the "show hidden files" there is a REFRESH button that you have to hit.
The JQuery-Monaca folder is under components, but you have to explicitly use the src="www/components/monaca-jquery/jquery.js" and that script has to come first, before the loader.js (which uses only src="componenets/loader.js" without the www/.
I don't know why this is so.
