Hi,
the bundle Id has nothing to do the start-level, it's controlled by
the sequence you specify bundle in feature.
Though you didn't ask, the spring status "Started" or "Waiting" also
has nothing to do with the start-level, it's possible the that lower
start-level bundle spring context completely up later than the higher
start-level bundle, this is actually from the OSGi asyn nature.
And business logic depend on bundle start sequence isn't good
practice in OSGi world.
The only way I know can guarantee the bundle fully start sequence is
hold the OSGi service reference, or use spring/blueprint event
listener in some cases also works.
You can get more details from a related discussion [1]

Excuse me but are very poorly explained.
I have a feature like this
<feature name="myfeature" version="1.0.1-SNAPSHOT" start-level='110'>
<bundle start-level='100'>file:location/bundle1</bundle>
<bundle start-level='95'>file:location/bundle2</bundle>
</feature>
When I install my feature I see in the console
[ 183] [Active ] [ ] [Started] [ 100] bundle1
[ 184] [Active ] [ ] [Waiting] [ 95] bundle2
I would have expected
[ 183] [Active ] [ ] [Waiting] [ 95] bundle2
[ 184] [Active ] [ ] [Started] [ 100] bundle1
thanks for the explanation

Hi,
This is exactly how start-level in OSGi works, "lower" start-level
means it
need start first.

Hello,
I need to know how bundle start level works.
I try to create a feture with two bundle
<feature name='my-project' version='1.0.0'>
<bundle
start-level='90'>mvn:com.mycompany.myproject/myproject-service</
bundle>
<bundle
start-level='85'>mvn:com.mycompany.myproject/myproject-dao</bundle>
</feature>
when the servicemix 4.4.1 (karaf) start and i make an osgi:list I
see that
myproject-dao load as first and not for second.
but this is not 'the result I expected
I missed something?
