Hi,
I figured it out.
The package import "org.apache.felix.service.command" in the manifest
makes the difference.
If absent the command is only executed with Felix as framework.
If present the command is also executed with Equinox as framework.
Thanks,
Stefan

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

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?
