It should be possible, I saw to suspicious things
in the code below;
1) You should register your SVGLoadEventDispatcherListener
before calling setURI, since loading is async it's
possible the thread get's past the SVGLoad dispatch
before your listener is attached.
2) The call the 'createWindow()' does just that creates
the window object, it doesn't tie it into the document
fully, so if your register code is depending on this
you might have problems...
That all said I'm not very confident that either of
those is really your problem.
Perhaps Batik doesn't think your document is dynamic?
Did you set the canvas to 'ALWAYS_DYNAMIC'? Otherwise
if your document lacks any event attributes Batik will
assume it's a static document and not dispatch any
events.
