Now Google push AJAX development

I recently posted about BackBase, an expensive (for commercial use) AJAX development thingy*. Well Google have produced something similar for free Google Web Toolkit. Although the end results are the same (as far as the user is concerned) there are important differences. The BackBase software is entirely client side. You write server stuff as normal, output BackBase code and the browser with JavaScript handles everything. The Google system is client and server orientated and odes more work on the server. The server also has to be running Java. It also has better browser support. This could be a reason for me to learn Java, something I’ve managed to avoid for quite a while now… * It’s actually an XML based markup language combined with a real time JavaScript processing engine.
