Re: Log4j 2.10 / slf4j 1.8 icw OSGI/Eclipse

[Rob Gansevles]

Hi Ralph,

I have a simple osgi plugin that just logs something to slf4j Logger in the
Activator's bundle start method.
When I install and start log4j-core-2.11.0.jar, log4j-api-2.11.0.jar,
log4j-slf4j-impl-2.11.0.jar
and slf4j-api-1.8.0-beta1.jar in a clean felix gogo shell, and then install
and start my plugin, it prints the No-SLF4J-providers-were-found message.

Should this not work out-of-the-box?
It does work if I do the same with log4j  2.9.1 and slf4j-api-1.7.25.

You can find my simple plugin on github: https://github.com/
rgansevles/osgi-slf4j-sample

Thanks in advance for looking into this,

Rob

Re: Log4j 2.10 / slf4j 1.8 icw OSGI/Eclipse

[Ralph Goers]

We have some unit tests that run to test our OSGi support and they are all 
passing. I don’t have anything that uses OSGi but I suppose if I can find a 
sample project I could give it a whirl. I just don’t know when. Between work 
and the other things I am trying to do for logging I don’t have much time.  
I’ll take a look at that link.

Ralph,

Do you think that release 2.10 broke OSGI support?
Maybe you can try it out if you have time.

It could be that the manifest has to be modified as described here:
http://aries.apache.org/modules/spi-fly.html#specconf
In that case i guess slf4j also needs to be changed.

I implemented the bindings for SLF4J 1.8 and they are in 2.10.0 but I have 
never tried it with OSGi.

Log4j 2.10 / slf4j 1.8 icw OSGI/Eclipse

[Rob Gansevles]

Hi,

I am trying to get Log4j 2.10 with slf4j 1.8 working in my eclipse plugin
project.

Slf4j 1.8 does not use the StaticLoggerBinder method anymore and it seems
to me osgi was depending on that.
It worked fine with Log4j 2.9 and slf4j 1.7

The error I get is the No-SLF4J-providers-were-found message.

So my question is, Is this a supported combination in an OSGI environment?

Thanks,

Rob
