Hi Jean-Baptiste,
Thank you.
The default-activation attribute was not explicitly set, so implicitly
it should have been eager.
I tried it with both values: same result.
JDK 1.5 or 1.6 makes no difference.
I made org.apache.karaf/karaf/2.2.1 the parent POM of the hello world
command POM (didn't help).
This is the reason for the Apache stuff appearing in the manifest:

It is somehow weired, it is such a basic thing and the core Karaf
commands work fine with Equinox...

Hi Stefan,
in the OSGI-INF/blueprint/*.xml of your command, what's your
default-activation (eager or lazy) ?
Could you try to use eager in place of lazy ?
Could you paste your MANIFEST also to see the OSGi package statements ?
Thanks
Regards
JB

Hi,
I have a problem extending the console with own commands, when I run
Karaf with Equinox.
To check this problem again, I installed a simple "Hello World" command
with blueprint and minimal dependencies on Karaf/Felix and on
Karaf/Equinox, both in a virgin state (deleted data directory).
With Karaf/Felix the command is executed, with Karaf/Equinox it is not
executed. Instead I get the error message "Command not found:
hello:world".
I am running the latest release 2.2.1, build on my system, but I have
also reproduced the problem with the 2.2.0 binary distribution.
The following log outputs appears only with Karaf/Felix:
org.apache.aries.blueprint - 0.3.0 | Retrieving service for bundle
org.apache.karaf.shell.console [22] and service registration

blueprintBundleContext
Up to this point the log output is equal with both frameworks (see
below).
What might be the problem?
