Google has just released its Ajax toolkit, called Google Web Toolkit:
"Google Web Toolkit (GWT) is a Java software development framework that makes writing AJAX applications like Google Maps and Gmail easy for developers who don't speak browser quirks as a second language."
Update, May 18: Bret Taylor, Product Manager of Google Web Toolkit, has dispelled the rumor:
"Morfik seems like great technology, but Google Web Toolkit is in no way associated with Morfik or based on its technology. There have been some rumors circulating on this list that have been causing some confusion, and I wanted to clarify.
