Hello
This is not a motion jpeg, but it can be used to accomplish your needs
without major complications
You can create a Panel with an image that replaces the image every time it
renders overriding the onBeforeRender method:
addOrReplace(new Image("image", new BufferedDynamicImageResource(image)))
and add AjaxSelfUpdatingTimerBehavior to the Panel with the specified
refresh rate.
I believe this is the easiest and most straightforward way of doing what
you need.
Cheers
