can we run two version of pax-logging in Karaf?

[Raman <ra...@yahoo.com>]

Hi,
        We have upgraded
Karaf from 2.2.3 to 2.3.0, while doing this upgradation we need to make below
changes to our manifest files in order resolve with updated version of
paxlogging.
 
org.apache.log4j;provider=paxlogging;version="[1.2,1.3)"
 
to
 
org.apache.log4j;provider=paxlogging;version="[1.2,2.0)",
 
 
Now, the problem is we have some bundles developed by 3rd party that have
org.apache.log4j;provider=paxlogging;version="[1.2,1.3)" in their
manifest file. How can we deploy those bundles without making any changes? The
solution crossed to my mind was having two version of pax-logging but with that
logging is not working.
 
Regards
Raman

Hi Raman,

Theorically, by upgrade etc/startup.properties, you should be able to 
deploy two pax-logging version.

However, it doesn't make sense for me, and the bundles should only 
define a import to log4j, slf4j, but NOT paxlogging. Like this it will 
work whatever the pax-logging version is in use.

As Pax-Logging use a ManageService, you may have an issue with the 
configuration loading.

Once again, I think it's not correct to import pax-logging: it's not the 
purpose of pax-logging to provide a logging facility itself, the purpose 
is to provide multiple logging framework in a central way.

That's why, it's better in the bundles to define the logging system to 
use without version. For instance, it's what we use in Karaf and Cellar 
itself: we import slf4j (not pax-logging).

We put pax-logging as provider in manifest to make sure pax-logging is picked
up instead of any other log4j deployed in container. As we use Karaf as a
container, there is a possibility that others may deploy log4j into
container.

If we update etc/startup.properties with two versions of pax-logging bundles
how pax-logging.cfg is shared? We tried that option seems logging is not
working. I can verify again.

Raman
