RE: [LIKELY JUNK]Re: [equinox-dev] Keeping the OSGi frameworkfromtermina

["Kirchev, Lazar" <l.kirchev@xxxxxxx>]

Thanks, the osgi.framework.activeThreadType property works fine for us.

 

As for the osgi.noshutdown property, is it possible its description to be changed, so that this becomes clear from it? Beacuse the current description suggests that it really keeps the framework alive.

 

Regards,

Lazar

That is correct. Another option is to have one of your bundles start an non-daemon thread itself. This has issues though because once your bundle stops (which should stop its own thread) then the VM will stop.

Thanks a lot.

We are starting the framework with java -jar org.eclipse.osgi.jar. As far as I can see, in this case the only way to keep the framework running without any applications is to use the property osgi.framework.activeThreadType and cannot be achieved with osgi.noshutdown. Is this correct?

Lazar

The osgi.noShutdown option is used to disable the code in the launcher that shuts down the framework and calls System.exit once it has gained access back to the main thread. If you are running no eclipse application then the main thread will be returned back to the launcher (org.eclipse.equinox.launcher jar) immediately. If you are not using org.eclipse.equinox.launcher to start equinox then you may not need this option. If you are just using java -jar org.eclipse.osgi.jar then this option is automatically set for you.

The way to shutdown any OSGi framework is to call Bundle.stop() on the system bundle (bundle id = 0)

BundleContext context = getContext()
context.getBundle(0).stop();

HTH.

Thank you, Ali, this works just fine.

But still, does anybody know what is the effect of osgi.noshutdown? Because by setting osgi.framework.activeThreadType to normal, the framework stays active with no applications, regardless if osgi.noshutdown is set to true or not.

And one more question - if using osgi.framework.activeThreadType, is it possible to shutdown "gracefully" the framework?

Lazar Kirchev

Set "osgi.framework.activeThreadType=normal" in your config.ini or pass that to the jre (via "-D") and it should do what you want

Hello,

I have a question regarding the configuration property osgi.noshutdown and the corresponding command line parameter -noExit. According to the documentation for this property, "if "true", the VM will not exit after the eclipse application has ended". We are launching Equinox from command line, with osgi.noshutdown set to true in the configuration file, and also with eclipse.ingnoreApp set to true. We want to have a running framework, which is not executing any application. But still, the framework terminates. Isn't this in odds with the documentation?

In bug 183208 is described a similar case. It is commented there, that the VM exits if there is no non-daemon threads running, and the framework does not start such threads, and the bug is closed as resolved. But then what is the osgi.noshutdown property for? Since the framework exits, then the property does not do what it should. In this case, how can we achieve running the framework with no application, and without the -console option, if possible?

Kind regards,
Lazar Kirchev
