Hello,
I'm thinking about designing an application using Eclipse E4. I was wondering if Eclipse e4 is a good choice (it seems to me) :
The application will be configurable to electronical devices. Only one at a time. To make it simple, there is one controller interface, and several possible controller implementation. I would like to offer the possibility to the user to switch the implementation (including or not the aplpication restart...). Is that possible and how ?
I've already done some tests and I plan to use Eclipse E4 with OSGI Declarative services. Right now I would like to be able to chose at runtime (from my application code), what component/bundle will be started at application launch.
One main point is the flexibility. Users will be allowed to develop plugin and install them in the application.
Thanks

To run the code just create a new osgi run configuration, include the 5
projects and equinox ds then add required plugins and specify
-Dosgi.console.enable.builtin=true
to get the good old osgi console back
a gui will popup
look in the console and start and stop the store and user bundles. You will
see that the gui changes. To keep it on top go to the control class and
specify SWT.ON_TOP
It is a bit shitty but enough to understand the service dynamics
