i dont think i really understand what you mean with the first advice. No
matter what classloader i set the the EngineConfig, it is restricted to
the engine instance that executes the main report.
This main report knows the ReportAdapter class and has a hyperlink to a
subreport. It seems to me that his subreport isn't executed by the engine
instance and therefore does not know anything about ReportAdapter.
So how can i "tell" BIRT that the app context is known globally?
