I am new to j2ee and jsr168. They seen very heavy and hard to use. I am interested in building an ajax dashboard that calls xaction files on the back end to send xml to a browser.

The dashboard is using:


Filter and Embedded report could each be a url returns xml.
PieChart and Widgit grid would need to point to server side images.

Is there documentation on how to access components with the ?getimage argument via javascript ?
