i haven't been able find solution other 'add library project'. seems though there missing step somewhere...

you need add library dependency module needs it.

choose project settings > modules. select module needs library (in case seems have 1 module in project, chatbot). select dependencies tab. click '+' button , choose library...). finally, select mysql-connector.. library added project.

edit: see wasn't problem @ all. problem code have unhandled exception class.forname(). method can throw checked exception: classnotfoundexception, must handled adding catch or adding throws classnotfoundexception method signature of getconnection().

in such cases error in code, easiest way figure out what's wrong move caret code red squigly line , see idea says in bottom status bar. alternatively can hover mouse pointer above , error message presented popup.

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
