Hi,
This is interesting. Actually Servicemix 4 and OSGI give a much more fine
grained control in terms of staging applications than Servicemix 3 due to
richer OSGi based lifecycle operations support.
As far as best practices go, when you deploy service assemblies in OSGi in
the following way
a> Ensure that you deploy using
servicemix> osgi install
jbi:mvn:com.mycompany/foo-sa/1.0-SNAPSHOT/zip
b> Set the OSGI bundle level
servicemix> osgi start-level <bundle-number>
servicemix> osgi start <bundle-number>
c> You could deploy using a batch file that could source the above
commands via a shell script using the utils commands for e.g
servicemix> utils exec foobar.bat
The above 3 steps should help you to craft a strategy that allows you to
deploy your JBI applications in a staged manner.
What is more setting the bundle-level will ensure that you can stage your
deployment in a very fine-grained manner. This staging will hold good on any
subsequent bouncing of your container as well.
Hope this helps.
Cheers,
Ashwin...
