Need advice on interactive map as a result on the html page

[mchmiel]

I would like to ask an advice on building a sevlet (or EJB) such that could
present a user an interactive fragment (possibly an applet) that could allow
user to change graphics objects on the map and then pass it in return to
server to generet new page. Is it possible, which of java technology to
use, should i combine flash to use it as a drawing component??? Please help

It is easier to think of this problem by not trying to send the modified
graphics back to the servlet, but to express the display (map, schematic,
visualization) as an abstract data model which is rendered. The user's
actions are really changes to the underlying data and these actions (or the
modified data model) are what are sent back to the servlet. Consider a
"design-your-own-T-shirt" web application. The web page shows the T-shirt
and the user adds logos, graphics and text. The picture of the T-shirt is
not the data structure--rather the data model is really just a list of logos
and graphics at specific positions. That data is used to regenerate the
picture in a new web page.

The decision as to whether to use an applet rather than pages is typically
made on how fast the user needs feedback. Applets and other client-side
interactions give highly interactive feedback. Web pages can be used for
many situations, but they simply take longer to regenerate per action.
