Hi,
I was actually developping a bundle in eclipse that can manage some
"Dynamic bundle". This "Dynamic bundle" are in fact Plugin Project in my
workspace that I install and start in current framework...
My problem is that these "Dynamics bundles" are often reloaded and this is
a performance problem. I view in debug mode that the osgi cache take a
long time to copy / remove files in the cache. I would like to disconnect
the cache for these specifics dynamics bundles.
Anyone have an idea of what can I do ?
Thanks for your help
Laurent

Hi Tom,
I effectively use "reference:file" to load bundle without caching all
this one.
Thanks Laurent.
