default autostart [message #125415]

There is a setting in the equinox launcher to set the default autostart to
true.
Is there a matching setting which can be placed in the config.ini file?

I found osgi.bundles.defaultStartLevel,
but osgi.bundles.defaultAutoStart does not work.

Is this an osgi param, or does the equinox launcher do this on its own?

Erdal,

A known workaround is to have a bundle (which must be autostarted, of
course) listening to new RESOLVED bundle and automagically starting
them. See the code below (from the Toast project ;-)).

However, you may want to check if your problem couldn't be solved
autostarting only a very few strategic bundles (e.g.
org.eclipse.equinox.ds, even if PDE will now automatically set it to
autostart), and have dependencies automatically handle the starting of
other bundles....

Cheers,
Ben
