Good idea can you add this as a jira issue in the aries project?
I know that you can define defaults perhaps that also helps in your case.

It would be great if I could get blueprint to spit out a message when
I'm missing a property and stall the startup of the container like it
does when you don't have a required dependency!

I am not sure about stalling the start but
update-strategy="reload"
makes the blueprint context restart when the config is changed. So it will
always reflect the newest config. In most cases this is good enough.
The config admin service always handles complete configs so it is more about
the file than the property.

I looked at Christian's tutorial here:
http://www.liquid-reality.de/display/liquid/2011/09/23/Karaf+Tutorial+Part+2+-+Using+the+Configuration+Admin+Service
However, I don't see anything that specifically says that the
Blueprint container will not start until the configuration is
provided. Also, does this mean that the configuration file is there
or that each property I try to reference is there?

Hi James,
you need to use managed Services via the Configuration Admin service.
Take a look at the blueprint documentation to find some more details
on how to create that.
Or take a look at some of those tutorials christian did. (I'm sure he
has a link in his signature :) )

You probably use start levels to work around this. OSGi services and
blueprint should help you
with this. You can make sure bundles only start when required services
or
configs are present.
We actually don't mess with start levels. Blueprint will put the
bundle into the "Grace Period" until it finds everything it needs.
However, I am intrigued by that last part there where you said I can
tell BP to only start when required configs are present. How do I
stall the BP startup when configs aren't present?
