Hi, Benjamin
I have tens of resources, if I will use extension point I should create
Resource class for each of them and add it to plugin.xml. I think the
best way is analize folder with resources and register each of them
using IResourceManager as Stefan suggested. I did not find a way to
unregister resources using IResourceManager, it is possible? My
application generates some images for HTML dinamicly, so I need a way to
remove them when user will be finished browsing. Now I found only one
mean to implement it - create special IServiceHandler which will manage
directory with generated images and returns image content when request
comes. It is alternative mean how my goal can be solved.

Hello Boris,
unregistering of resources isn't available in RAP as images are treated as
shared objects between session. This assumption is true for most of the
use cases. But there are use cases (as the one you're describing) where
this isn't true.
I've been discussing this with Stefan before because he has implemented a
solution using the servicehandler approach. Unfortunately this solution
isn't generic enough (we encountered several other use cases during that
discussion) to take this over into the RAP.
To trace this I have created an bug entry:
245635: Provide an mechanism to handle different lifetimes of resources
https://bugs.eclipse.org/bugs/show_bug.cgi?id=245635
Ciao
Frank
