HTTP-Plugin with dynamic port from configuration? [message #94916]

Hi

I know that I can set the system property "org.osgi.service.http.port" to define the port for the HTTP-Plugin. In my case, the port should be read from an external configuration file and is only known after my application is started. Currently, I set the system property in my code but I also read, that "osgi.*" properties should be defined outside of the runtime (and not in code).

The second problem is that the next time I start my application, the HTTP-Plugin is started before my application and the port is not set yet. Starting with -clean works around the problem. I tried changing config.ini but had no success.

Is it safe to set the property in the code or is there some other way to define the port?

Thanks, Stephan

Hi Stephan,

I would only use System Properties if you know which port you want to use
beforehand, when launching the process.

If you're using the Jetty based implementation you might want to take a look
at JettyConfigurator and use that to explicitly start your instance each
time.
You can also do the same thing using ConfigAdmin service which will
persistently save your port (and other) settings.
