Hi Sergey,

A while ago, I tried to configure logging in CXF D-OSGi. I deferred this task 
since I had some higher priority tasks to do, but now I am confronted with this 
problem again.

In the meantime, I was able to get pax-logging working with my own application. 
So all logging output that I do through the standard Log4J interface 
("org.apache.log4j.Logger") gets directed to pax-logging. I just had to make 
sure that there are no other bundles exporting the same logging interfaces in 
my container. 

But CXF, on the other hand, still logs to the console. In detail, I get this 
log output for each request that is sent to my application:
08-Mar-2012 16:29:10 
org.apache.cxf.dosgi.dsw.handlers.SecurityDelegatingHttpContext handleSecurity
INFO: No filter registered.

I checked the source for this logging output and it is produced by a logger 
that comes from "LogUtils.getL7dLogger(SecurityDelegatingHttpContext.class);". 
I checked this one again and it uses java.util.logging by default. I thought 
that maybe java.util.logging is not redirected to pax-logging (although it 
should be possible).

So  I tried to switch CXF to Log4j since this is definitely send to 
pax-logging. Therefore, I had a look at the link you provided last time and 
found the possibility to set the system property " 
-Dorg.apache.cxf.Logger=org.apache.cxf.common.logging.Log4jLogger". To be on 
the save side, I checked if the Log4jLogger class uses 
"org.apache.log4j.Logger"; According to the source I found, it should use this 
class. Therefore, output done via Log4jLogger should be redirected to 
pax-logging. 

So I tried to set the system property in my Felix container. I set it when 
starting Felix from the command line and I set it in a file called 
"system.properties" in the Felix configuration directory. But I am still 
getting the same log messages. So I guess that CXF does not find the system 
property. 

Does anybody have an idea where to set this property in Felix (and perhaps also 
in Eclipse) so that CXF can find it? I could also try the second possibility 
with the file on the classpath, but I am not sure how to do it. My first idea 
was a fragment bundle, but since I am now using the multibundle version of CXF, 
I have no idea to what bundle I have to attach the fragment.

Many thanks in advance,
Sven

I run a zookeeper instance in a separate JVM, but I did set a -D system 
property when starting a Felix instance to make sure no random port is 
picked up. The guide at
http://cxf.apache.org/dosgi-discovery.html

is out of date so after observing the discovery demo not working as 
expected I installed those 2 extra bundles, set the system property and 
it started working... To be honest I'm not even sure those two bundles 
made a difference :-), all I was concerned about was to make sure the 
existing demo was still working, the distributed discovery was of the 
least concern for 1.3, rather it was to solve various minor but blocking 
issues and kick start the process again... Nothing changed with respect 
to the distributed discovery except that the legacy zookeeper wrapper 
bundle was removed.

Please try the discovery demo - and if you can't make it work then I'll 
try to reproduce the way I did it.

CXF should be able to work with different logging frameworks, please see 
this section:
http://cxf.apache.org/docs/debugging-and-logging.html#DebuggingandLogging-LoggingMessages
