How to register a new service to start at the server start up time
hello,
I have created a new service for JMX(api and implementation) and now I want
to start it with the server start up. Where should I register the service
so that JMX service will start at the server boot up time ?
Thank you.

Re: How to register a new service to start at the server start up time
Posted by Rajika Kumarasiri <ra...@gmail.com>.
hello,
I got the proposed POC working for
https://issues.apache.org/jira/browse/MARMOTTA-408. It seems the jira is
offline for maintenance so I will add the information here. I will copy
the same information into the jira when it's online.
Please find the attached patch and the screenshot.
The screenshot shows how I exposed the OS and JDK run-time
information(similar to System->Statistics->System ) using a MBean from the
newly developed JMX infrastructure.
The classes;
a). org.apache.marmotta.platform.core.api.jmx.JMXService
b). org.apache.marmotta.platform.core.services.jmx.JMXServiceImpl
c). org.apache.marmotta.platform.core.services.jmx.JMXRMIRegistryController
d). org.apache.marmotta.platform.core.services.jmx.JMXMBeansRegister
e). org.apache.marmotta.platform.core.services.jmx.JMXAdapter
are responsible for #1 in the jira. The mentioned MBeanRegister API is
defined in JMXMBeansRegister (d)). It has the APIs to register and
unregister the MBeans. The other classes basically create a JMX connector
and starts it with the platform. I consumed the SystemStartupEvent to start
the JMX CDI service.
The interface and class;
a). org.apache.marmotta.platform.core.services.jmx.SystemStatisticsMBean
b). org.apache.marmotta.platform.core.services.jmx.SystemStatistics
are an example for #2. They collects the stats about the OS/JDK run time
data and register them into #1 using MBeans so that we can view that
statistics using JConsole(or any other JMX client). This is what can be
seen in the screen shot. I just implemented this logic inside
org.apache.marmotta.platform.core.services.jmx.JMXServiceImpl itself but it
should be implemented in each place where those stats will be collected
(for example
org.apache.marmotta.platform.core.services.statistics.system.SystemStatisticsModule).
Now the next step is to identify various places, components or modules
across the platform and other places and replace them with relevant MBeans
and register them with the MBean server similar to #2 above. #1 also need
to improve so that other jmx parameters can be configured(for example SSL
connections).
Do you think I am heading in the correct direction ? I would like to start
writing my proposal based on this information once I compiled a list of
places to have new MBeans to collect respective statistics. I am aware of
JUnit and each of this new feature will be covered with a JUnit test case.
Please let me know your feedback or any comment.
Sorry for the long email. For sure if you prefer we can continue the
discussion in the jira as well.
Thank you.

Hi Rajika,
if you want your CDI service to startup automatically (e.g. because it
needs to register something somewhere) you should listen on the
SystemStartupEvent which is fired once the system has come up
completely:
// trigger startup once configuration service is finished with initialisation
public void initEvent(@Observes SystemStartupEvent e) {
// nop;
}
Best,
Jakob

helo Sergio,
Thanks, will try that. Sure will provide a documentation enhancement patch

The services are in the end CDI services (JSR346), using the JBoss Weld
implementation.
So you just need to add to your service class the annotation with the
necessary scope, in this case @ApplicationScope. Then the platform will
instantiate it, and you can normally use IoC with your new service in
the rest of the platform.
Further details at:

If you miss anything else in the documentation, contributions there are
also welcomed ;-)
