As Tim explained your bundle has the requirement for a LogService OSGi
service in its Manifest. Since I think karaf 4.0.5 requirements for
services are also checked by the feature service of karaf. In version
before these requirements were ignored.
The problem now is that not all bundles that provide such services also
define a capability for them in their Manifest. So while the actually is
a LogService in karaf that is provided by pax logging this service is
not announced statically in the Manifest using a Provide-Capability
header. So in fact this is a bug in pax-logging as it should provide the
capability. I will take care of an issue and fix at pax logging.
You can fix this quickly by either switching off the functionality of
karaf to look into service requirements or by providing the capability
in config.
1. Edit etc/org.apache.karaf.features.cfg and set
serviceRequirements=disable
2. Edit etc/config.properties and a line to
org.osgi.framework.system.capabilities=
osgi.service;effective:=active;objectClass=org.osgi.service.log.LogService
The solution 2 wrongly attributes the LogService to the system bundle
but this should still work.

The missing requirement indicates that you need a Log Service implementation
(i.e. someone to provide you with the service). The dependency that you’re
compiling against is just the API (which is a good thing to compile against)
but you actually need an implementation at runtime. Your build tools know that
you need this service, and so have added a requirement for the service to your
bundle. Your bundle therefore will not resolve until you have installed a
bundle which declares that it provides the service!

Hello,
I developed a SOAP service which is encapsulated in a kar archive. Then, I
made a custom karaf distribution from Karaf 4.0.4. Everything works fine (no
error message in the log files and the service works fine).
The problem is when I try to do the same thing with Karaf 4.0.8, I got this
message during the deployement :
missing requirement [...] osgi.service; effective:=active;
filter:="(objectClass=org.osgi.service.log.LogService)"
How can I inject the service "org.osgi.service.log.LogService"?
In my class, I have :
protected LogService logService;
public void setLogService( final LogService logService )
{
this.logService = logService;
}
In the file pom.xml, I have :
<dependency>
<groupId>org.osgi</groupId>
<artifactId>org.osgi.service.log</artifactId>
</dependency>
Must I use <import-service> and if yes, what must be the contain of this
element?
It seems that the LogService service is not satisfied anymore and it seems
to be the same problem that is specified here :
http://karaf.922171.n3.nabble.com/VOTE-Apache-Karaf-Container-4-0-6-release-td4047647.html
Please, could you help me please?
