Hi. I am interesting in the differences and similarities with technologies in the title. I am
Java programmer, but oriented especially to back-end.
I am little confused about usage of Ajax or GWT, particularly and how the JavaScript and XML are involved into. I ask this because, I found a plenty of books, the whole assortment devoted to these technologies ( you have a bunch of books related to JavaScript, a bunch related to Ajax, a bunch related to GWT). My question is: should I start, let say Ajax with book "Ajax in action", as an example, even if I have no knowledge of JavaScript ( is that wrong?). Or should I start "GWT in Action", also without knowledge on JavaSript (would I find there a necessary knowledge about JavaScript?).
Or I NEED to O'Reilly's 'Learning JavaScript' books first ( how they are related JavaScript-Ajax-GWt)? I mean what is the BASE and what is UPGRADING ?
Thanks...
