I'm currently developing an application which should handle plugins.
Everything works fine except one plugin, which makes use of the osgi'd
version of httpclient.
I google'd alot and didn't found something useful that tells me how to
fix this.
i also posted this on
http://www.coderanch.com/t/555730/oa/osgi-felix-NoClassDefFoundError-org-apache#2521416
but i'm pretty sure that no one there can help me with that specific topic:

i used the springsource commons logging jar which is osgi'd, it also
exports the org.apache.commons.logging.LogFactory in its Manifest:
Export-Package:
org.apache.commons.logging;version="1.1.1",org.apache.commons.logging.impl;version="1.1.1"...
and i tried it with pax logging. When i use pax logging and include it
as dependency in my main bundle (which starts everything) in netbeans i
can debug the whole osgi project and the plugin works.
i then get a lot of debugging output whats currently going on
(connection information including http content).
