Oh yeah, jMaki "rules" at DUCS (Delhi University Computer Science Deparment) 
It was very much expected, especially after the last talk i gave. It was on Building Ajax applications with NetBeans 6.0 .
In that demo, i talked in brief about various jMaki (not jMonkey) toolkits and that really took students by surprise.
They were left impressed to see the ease by which one can create good looking web pages.
Although all widgets are pretty good and come handy for various requirements but some of my personal favorites
which i plan to use in building my website(as a part of my semester project) are:
--> jMaki Dojo
<> Accordion (for leftsidebar)
<> Drop Down Date Picker
<> Fish Eye (really cool one)
<> Tabbed View (this one u gotta see) -- much like orkut tabbed profile browsing
<> Tree (for making sitemaps)
--> jMaki Google
<> Map
--> jMaki Yahoo
<> Menu
<> Tooltip
<> Slider
After using these basic widgets, one might want to divulge into details, and make your widget and hence your
application more useful by binding the widgets with the back-end database.
To do so, the ideal place to start with is to see the following entry:
Dynamic data in jMaki Widgets
A big thanks to Arun Gupta for making the task look so simple.
Other such entries:
Dynamic Ajax Table Example using jMaki and JPA on Glassfish
CRUD using jMaki & JPA
I'm still hunting more tutorials on using jMaki toolkits.
The one i always look back is located at JavaPassion.Com
Other than that, i would recommend students to post queries on various online forums that exists to help you out:
-- java.net forum - Project jMaki
-- java.net forum - Project Glassfish
Also have a look at Ajax FAQ's for more information on Ajax.
Please drop me a comment if you have some useful links.
