In Karaf 3, you have to use the Felix Gogo services, ie the CommandProcessor.

From a CommandProcessor, you can create a CommandSession and then call execute on this session.

Two notes on this:

In Karaf4, the service has changed - it's not dependent on Gogo anymore
All the shell commands use an underlying osgi service. It's always better to use this service instead of creating command and "parsing the outputstream". For example, you can install a Bundle with BundleContext.installBundle or install a feature through the FeaturesService

Your command, for example, use the org.opendaylight.snmp4sdn.ICore service. See: PrintDB
