Start/Stop Karaf 2.3.x via JMX
Hello,
I have a requirement where we are required to control Karaf from outside the
container, like start/stop bundles, uninstall/install features or bundles. I
was able to do it via JMX using:
serverConn.invoke(new
ObjectName("org.apache.karaf:type=features,name=root"), installFeature, new
Object[] { <feature-name> }, new String[] { "java.lang.String" });
However, I could not find any command to start or stop the Karaf container
from outside via JMX. Is it possible to do this?
Any pointers/link to example will be greatly appreciated.
thanks,
Asha

Starting the container is of course not possible directly as the mbean
server is only started when karaf is started.
What you can do though is start a master instannce of karaf and use the
admin/instance mbean to start and stop
child instances.

Hi Asha,
no argument for the shutdown() operation, so you can directly invoke the
operation.

I tried to shutdown the container, but I got the following exception. Is
there some settings I need to modify to let JMX shutdown the container. I
used the shutdown command in "org.apache.karaf:type=system,name=root" to
shutdown Karaf 2.2.9.

Thanks, I found a test program at

Thanks Jean-Baptiste for the quick response. Are you aware of any
samples/test that use it via MBeanServerConnection. I tried a few things,
but none worked. Does it need any arguments passed to shutdown the
container?
thanks again,
Asha

Hi Asha,
in org.apache.karaf:type=system,name=root, you can find the shutdown
operation to stop Karaf.
For start/restart, it's not available in Karaf 2.2.x.
Since Karaf 2.3.x (so 2.3.0 ;)), in
org.apache.karaf:type=system,name=root, you have the following operations:
halt() - to stop Karaf
halt(String time) - to stop Karaf at a given time
reboot() - to reboot Karaf
reboot(String time, boolean clean) - to reboot Karaf at a given time and
eventually cleanup the data folder
Regards
JB
