Subject [jira] Commented: (FELIX-428) Support Application supplied Logger instance for the framework
Date Wed, 05 Dec 2007 01:19:42 GMT

Lucas Galfaso commented on FELIX-428:

Ok, now I think I got close to the complete picture, but there is still one more thing that
I do not understand.
 .) The user will have to be aware that if the Log service is installed ...

No. The initial Logger is only used for framework logging. If users use it for other things,
so what. It is not good, but none of our business. Of course "users" should use LogService
if available becase using a LogService has more advantages than just logging. For example
the LogService will also log the source bundle of the log message.

Now, the patch would allow a developer to override the method "doLog" and that method will
be called up to the point that a LogService is installed. Once a LogService is installed the
"doLog" method will no longer be called when the framework logs, so I do not fully understand
how this patch fits in your specific needs.

> In certain environments where the Felix framework is embeded, the environment may provide
a logging facility which should be used by the framework as long as no OSGi LogService is
> For example, in Sling we have a web application based launcher, which embeds the Felix
framework in a web application. In this case, it would be usefull to have the log messages
being directed to the ServletContext.log methods until the LogService is set up.
> Will attach a patch to implement this feature.
> WDYT ?
