Migrating SVG/AJAX to Batik?

[Cyannick]

Hello,

I'm currently working on an application that use a AJAX structure to update a SVG file (change colors, hide element, open new window with svg ...). This SVG is displayed in an html page, and javascripts are loaded in the html page too.

We would like to migrate the display of those files in a java application, since we are already migrating some other old parts to java.

I read in Batik home page and in here about javascript support, but I could not fully grasp the extent of that compatibility.

To be able to fully use our javascripts, do we need to make some adaptations? (with Batik, or Rhino as I read)
Or does JSVGCanvas automatically load external javascripts and use their functions? (provided that javascripts are loaded in SVG files)

Can Batik (listeners I suppose) catch a modification to the SVG file made through a javascript function?


Thanks for your help.

   The JSVGCanvas will automatically load external javascripts and
run their functions (as appropriate).  You can test it standalone
with the squiggle SVG Browser included in the standard Batik
distribution.

   Yes, Batik fully implements DOM level 2 Events, so you can register for
mutation events (in either Java or JavaScript).
