A.S.,
You can accomplish something similar by using AJAX-enabled
JSF components like the ICEfaces component library that is integrated with MyEclipse. I don't know if you'll find tooling in general with
Java IDEs as integrated as Visual Studio because Microsoft has the advantage of being able to focus their entire tool and framework stack against 1 technology, where as the Java environment has 100 solutions for every 1 problem. It's a blessing and a curse.
Ultimately I would suggest using whatever tool makes you the most productive (both financially and time-wise), that's all that matters wether it's Java, ASP.NET, Perl or CGI
