Thanks for the replies everyone (including Mike Evans). I've got a few |

I'm not sure what you mean by config.ini, but I guess perhaps you're
talking about making an Eclipse product? I.e. shipping your own branded
exe file? By "Eclipse Application" I meant one of the possible type of
run configurations in your "Run" or "Debug" menu.

Back when I first posted this, I'm pretty sure my org.eclipse.equinox.ds
bundle *was* autostarted. However, I could not get the example working
unless I also set my own plugins (org.equinoxosgi.toast.client.emergency)
to start, even though I've specified the "immediate='true'" attribute in
that plugin's component.xml file.
Just to confirm: What I initially experienced was abnormal, and in theory,
you only need the org.eclipse.equinox.ds to be autostarted, and all the
others can be set to lazily started in the launch config; and the
org.eclipse.equinox.ds plugin may start up my bundles eagerly despite what
I've specified in the launch configuration if the component.xml file
states that they should be eagerly started?

My understanding is that DS needs the bundle started event from the OSGi |
framework in order to look for the service component definition files.
So if your bundles are not started by "something", then DS will not know
your bundles exist and so will not attempt to create any service components.
