We are evaluating AJAX based frameworks. GWT is one of them. It is easier to use because one writes in Java and toolkit does the dirty work of generating Javascript GWT supports only java.lang and java.util package ,isn't ? Just wanted to know others experience on GWT. [ November 13, 2007: Message edited by: Bear Bibeault ]
Please be sure to take the time to compose descriptive subjects for your posts; read this for more information. Most posts this week will regard GWT, so a subject of "GWT" isn't very useful.
I've had great experiences with GWT. But I never became a great JavaScript developer. GWT was a huge help in forgetting about JavaScript issues and moving forward with application development.
GWT does support java.lang and java.Util. This gives you the basic Java types including collections and exceptions. Number and date formatting were added with the 1.4 release and I'm sure more support will arrive. One thing to note is that the code must run in a browser so supporting more complex Java packages like database drivers isn't possible.
