Hello, I am a certified newcomer to all of this. Searching on google for ajax.js gives me multiple results which all look like different libraries. Does Tapestry provide an ajax.js library? Does JQuery provide an ajax.js library? What other ajax.js library should I use to generate my POST? Is the POST request I generated buggy? How would using the other library help me?
