would you actually suggest switching to spring-osgi? does spring-osgi
already use the maven-bundle-plugin?

Hi,
Sorry for posting again and again about the same issue, but I just have
problems getting it done.
I fixed a couple of things in my pom file now using the patch of the
bundle plugin (felix 308).
I did set up a very simple maven project (basically a simple artifact),
imported log4j as dependency, set the packaging to "bundle" and set the
dependencies the following way:
I use <Embed-Dependency>*<Embed-Dependency> and
<Embed-Transitive>true</Embed-Transitive>
still, the bundle cant be started, because of the following missing
dependencies:
Missing imported package com.sun.jdmk.comm_0.0.0.
Missing imported package javax.jms_0.0.0.
Missing imported package javax.mail_0.0.0.
Missing imported package javax.mail.internet_0.0.0.
welcome to the world of OSGi :)
these are dependencies that aren't declared in maven because they're
normally found in the Java runtime... however, because their packages
don't start with java.* the OSGi framework does not export them from
the bootclasspath (this is so alternative versions can be provided).
there are a couple of ways to solve this:
a) mark them as optional imports, for example Spring-OSGi uses:
<Import-Package>
com.sun*;resolution:=optional,
javax.*;resolution:=optional,
org.w3c.dom;resolution:=optional,
org.xml.sax;resolution:=optional,
org.xml.sax.helpers;resolution:=optional,
*
</Import-Package>
b) use the org.osgi.framework.bootdelegation OSGi property to get
the OSGi framework to surface the required additional runtime
packages (ie. set it to sun.*,com.sun.*,javax.*)
c) add bundles that provide these packages
most people choose a) because it's simpler, more portable (ie no extra
setup / bundles) and those packages are _not_ required for general use
of Log4J.
FYI, you might want to look at the Pax-Logging bundle:
http://wiki.ops4j.org/confluence/x/F
which provides a range of logging APIs that use a single Log4J backend.
HTH (ps. I've copied this to the felix mailing list)
my (very simple) POM file can be found below:

not sure this is what you want - here you're saying that all packages
on the compilation classpath should be marked as 'private' and not
exported... perhaps try <Export-Package>*<Export-Package> ?
<Embed-Transitive>true</Embed-Transitive>
<Embed-Dependency>

is there any problem in the pom?
