Hi,
i'm sorry if this is some kind of noob question (since today is the first
day i am experimenting with apache felix - and OSGI in general), but i can't
find a solution on google or in this forum.
I created a bundle for my swing application.
Although i know that i have to find a solution to my log4j logging problems,
this is not the main problem.
Here is the output after starting felix:
<code>
Welcome to Felix.
=================

a "org.apache.log4j.Appender" variable.

Shouldn't this class be part of the jdk itself?
I started Felix with the custom framework launcher from
http://felix.apache.org/site/apache-felix-framework-launching-and-embedding.html.
Is this problem related with my custom launcher?
Maybe someone can help me with this problem (or even with my log4j problem)
Best regards,
Niko
