Is OSGi log service a mandatory requirement for Felix web console?
Contrary to the documentation [1], I am getting following error if I try
to start Felix web console (version 1.2.2) in an environment that does
not have OSGi log service:

To work around this, I had to install Apache Felix Log Service
(0.9.0.SNAPSHOT).
Thanks,

While this sounds useful for most cases, i don't see much benefit from NOT
requirering an installed compendium in case of a _webconsole_.
Otherwise compendium could be just included and exported to keep things
simple.

Sounds like a bug to have it as optional but still require it at
runtime (if the console actually does not work). The implementation
might want to use reflection to see if the classes are available at
runtime. For an example of that, look at the actual framework code
that does something similar.

Yes, webconsole fails to start when that error occurs.

Its org.osgi.service.*;resolution:=optional,* in webconsole. I don't see why
this is optional while they do not provide it (included) themselves.
Actually it makes webconsole crash, right, Sahoo ?

Well, org.osgi.service.log.LogService should be provided by the compendium
which you need to have installed.
I wonder why webconsole does not require it at resolve time..

Sahoo,
It should not be necessary to have an *instance* of the LogService
available. But so many things in OSGi depend on the LogService
interface that you should at least have a bundle exporting it.
Typically I always have the osgi.cmpn.jar bundle (downloaded from
osgi.org) installed in my framework, whether I'm using Felix or
Equinox. That bundle exports all the interfaces found in the OSGi
Compendium specification.
Regards,
Neil

Re: Is OSGi log service a mandatory requirement for Felix web console?
Posted by Felix Meschberger <fm...@gmail.com>.
Hi Sahoo,
As Marcel Offermans noted, this is most certainly a bug in the Web
Console. The intent was, as is reflected in the optional resolution of
the org.osgi.service.log package, that the WebConsole might run without
a LogService API available.
But as Tony Menzel rightly says, it is probably ok for the Web Console
to just require the org.osgi.service.log package and fail to resolve if
missing.
On the other hand, fixing this is trivial enough: The Logger class does
a "LogService.class.getName()" to specify the name of the LogService for
the ServiceTracker. By just using a String constant, which does not use
the LogService class, this can be fixed and the Web Console can be run
without the LogService package.
I have created FELIX-916 for this and committed a fix in Rev. 740435.
Regards
Felix
