The high-level requirement is something like this : If I develop a certain product, how much will it costs me? This generated cost will be used to compare with the cost the vendors have quoted and to come-up with ...

Hi, I am writing a desktop application using SWT. What is the simplest way to update GUI controls from another thread? ...
We basically need to be able to adjust behaviour at start-up time, by providing desired classes to be produced by various factories inside our application (to avoid the hard binding of the "new" operator).
