Re: [equinox-dev] app model demo

[Jeff McAffer <Jeff_McAffer@xxxxxxxxxx>]

I tweaked the wiki by moving the content
for that demo to its own page and doing a few edits.  

i also tried running the headless launch
config but could not get it to run.  Is there some magic?  I
get an error about the applicaiton not being found (we likely don't actually
want an Eclipse application to be found right?) and the app bundle is left
in STARTING state

I updated the wiki (see http://wiki.eclipse.org/index.php/Equinox_Demos#Application_Model).
 I spent some time creating a UI front end.  Its nothing fancy
but it seems to work good enough.  I did not spend any time making
the console commands any better.  I don't want to spend any more time
on this demo right now. 

TODOs after EclipseCon 

- make app console commands more user friendly 
- provide instructions for running on foundation. 

Tom.

Can you put up instructions of rhow to run this on Foundation?

Console is definitely good enough. Actually I'm thinking it is even better.
 feels retro but new at the same time :-)

Ok on the registry.  Some configuration that does not include the
runtime (and its prereqs would be cool)  I could not get that to wokr.
