Notes: servlet-api is not required in a servlet container environment,
since this api is provided by the container and should be injected
through the system bundle. The osgi.services jar should probably not be
place in the lib and the bundles folder, one location should do it.
I suggest to add an OSGi LogService implementation bundle, such that you
get logging of OSGi events as well as the web console itself (and others).

If you could send me your web application directly (off-list), I could
try to find out, what exactly is going on here.
