Hi,
Thank you for your answer,
That was just what I wanted to do. My scenario is easy, I just wanted
use Log4J Api in one of my bundles, the problem was that I did not
know how to include a external library using Eclipse IDE and
Manifest.MF, so I included in bundle Classpath firstly, then I
exported log4J.jar and I imported log4J.jar in the same bundle since
it is this one the only one which is going to use Log4J. After that If
I launch my bundle with log4J, Equinox is able to recognize Log4J.jar
but the problem now it is that Equinox is not able to find my
log4jproperties file like you told me. I got an exception
FileNotFoundException log4j.properties not found!
I have included my log4j.file in the same place that my
Activator.java, then I exported from Eclipse this Project in order to
have a .jar bundle, could you tell me where do I have to place my
log4jproperties file so that Equinox can locate it?
Thank you in advance
Regards
David

Hi, thank you very much for your answer.
I have tried to download the Pax Logging binary file but I have got
error with the web site.
If I am not wrong, the idea would be included paxlogging bundle as a
required bundle, in order to get the libraries log4j and
common-logging, to launch this bundle and use in my bundle log4j as
the same way as I did without Equinox I mean in normal java
applications, am I missing anything?
By the way, why I can’t to load the library org.apache.log4j.jar in my
bundle and simply to use it? If I have to use other external
libraries, what would I have to do in order to be able to use in
Equinox framework?
I think the simplest way you want is to change a log4j Jar file to a
log4j bundle. Just create a new bundle project, put log4j.jar in the
bundle directory, add log4j.jar to the project build path, export all
the packages in log4j.jar,(through Export-Package in bundle's
MANIFEST.MF), add log4j to the bundle class path (through
Bundle-Classpath in bundle's MANIFEST.MF). And then you get a log4j
bundle which can run on Equinox.
You want to use log4j APIs, just import log4j package in other bundle
(through Import-Package in bundle's MANIFEST.MF) and use it directly.
But in this way, loading of the configuration file log4j.properties is
a problem. log4j.properties can locate in the jar bundle or use a
argument to figure it out.
So using pax log is a better way to resolve the class loader problem.
Thank you in advance

PAX Logging at
http://wiki.ops4j.org/display/paxlogging/Pax+Logging is a good
solution, and the one I use. Another good solution is SLF4J at
http://www.slf4j.org/.
Both of those implement the log4j logging API and use standard
log4j configuration property/xml formats for configuration, which
is convenient if that is what you know.
Both of those also implement Commons Logging and other logging
APIs making it very convenient in an OSGi container!

*Subject: *[equinox-dev] Using Log4J in Equinox framework
Hi,
I have been trying to use org.apache.lo4j jar in Equinox but I got
an exception :
Java.lang.Error Unresolved compilation problems:
The import org.apache cannot be resolved
….
My framework is not able either to recognize or load this library.
I have in my Activator. Java the next one:
*import* org.apache.log4j.Logger;
*import* org._apache_.log4j.PropertyConfigurator;
Furthermore, I included org.apache.log4j.jar in my classpath,
either I installed this library like a bundle. I also tried to
install the bundle from Orbit which implemented log4J, but I
always have the same result.
Does anyone know what I have to do to use org.apache.log4J in Equinox?
I have either include import org.apache.log4j in Manifest.MF, I
guess that there is a way to load external libraries in Equinox
framework, other times I tried directly installing the jar file
and it was fine, but with org.apache.lo4j jar there is no way to
get a good result.
Any idea?
I am using Equinox by Console, not through Eclipse.
Thank you in advance
