Why would a bundle not start?

[Benson Margulies <be...@basistech.com>]

I have a container that I've installed some bundles into.

One of them has an activator. If I enumerate the bundles, I see this
bundle, I see that it has a persistent start level of 1. I start up Felix,
with the framework start level set to 1. My bundle's activator is not
called.

Do I in fact have to iterate my bundles calling 'start' even if they have
persistent start levels?

Yes exactly. OSGi never automatically starts bundles.

Start level n merely means that the bundle cannot start until the framework reaches that level, even if the Bundle.start method is invoked.
