| Re: [platform-dev] Using WeavingHook in eclipse |
It all depends on the context.
If you run from a product for example, add your bundle to the
configuration, set its autostart=true and startlevel=1
If you bundle is just an eclipse-plugin you would need to provide a
p2.inf to configure appropriate start-levels and edit your runconfig
accordingly.
