Start Service on Ofbiz Startup

[iwolf]

Hi everybody,

is it possible to start a service when Ofbiz has started and is ready?

Use case: I need to startup a connection to an external storage system. In my
case a TCP/IP connection that is permanent.

Best regards,
Ingo

Hello Ingo,

For this case, i think I would plan a job to run every X minutes, that
will check if the connexion is alive or, establish it.

The jobPoller will then take care of it after OFBiz is launched.
Depending on the connexion type it might be enough.

AFAIK there is no standard configuration to launch a service at OFBiz
start.

Is it important to establish the connection to the external storage
system only after OFBiz has been startet?

Can it be established beforehand? If yes, I would either startup the
connection in your OFBiz start script or completely independend of OFBiz
on the server level (mounting on startup).

Hello Gil,

that was my first try either, unfortunately that is not working as when I
restart Ofbiz, the service may crash and due to restarting a new pending job
will not be created. So the service status has to be reviewed everytime the
server is restarted and a new  new job has to be created. If the server is
restarted for some reasons Ofbiz will startup automatically but I want to
avoid having dependencies on someone checking the service -  or calling me to
do it.

Thanks for your thoughts!

Best regards,
Ingo

Yes it is important as the external storage, in my case an automatic storage
system, sends messages to Ofbiz if inventory is requested. If it has the
information that the connection is established, but unaware that Ofbiz is not
ready it will run into problems - or makes it more complicated.
I guess I will have to add the service database entries via the startup
script. I was hoping to find a "cleaner" way, telling ofbiz to do something
when ready.

Thanks for the input.

Hi Ingo,

You can implement an OFBiz Container and declare it in your custom ofbiz-component.xml file.
Also see Container.java from the sources.

Another possible solution is to implement ServletContextListener and declare it in your custom web.xml file.

James

Hi Ingo,

Please check the serviecengine.xml, you can define the startup-service
there, I think this will fulfill your requirements

===============
<!-- Start-Up Services -->
<!--
- runtime-data-id refers to the RuntimeData entity for in-parameters
- runtime-delay is the milliseconds after startup this service should run
- run-in-pool is the name of the pool to run the job in; defaults to the
send-to-poll (above)
<startup-service name="testScv" runtime-data-id="9900" runtime-delay="0"
run-in-pool="pool"/>
-->
==============

Hi James,

I decided to go with the ServletContextListener. It does exactly what I need.

Thanks a lot!
Best regards,
Ingo
