I may actually have this part working but I have compile errors (see
below) so I'm not getting this far yet.
I want to embed a set of third party libraries in my bundle. This
consists of five jars and one native code library (dbus-java-bin.jar,
debug-disable.jar, hexdump.jar, libdbus-java.jar, unix.jar, and
libunix-java.so). All of these files are in the lib directory of my
project. I've added the following line to the project's pom.xml.
<Include-Resource>lib=lib</Include-Resource>
That should embed the jar and so files. However, don't I still need a
Bundle-NativeCode header? Something like
<Bundle-NativeCode>lib/libunix-java.so;osname=Linux;processor=x86</Bundle-NativeCode>
How might I do this?
just add that to the bundle-plugin instructions - it should be copied into
the manifest (same with any other entry beginning with a capital letter)

I saw FELIX-308, thanks.

I guess that's my first problem. I believe that the Include-Resource
line above does this but I am getting compile errors. The compiler
can't find any of the classes in my embeded jars. How do I get the
compilation kicks in before the bundle-plugin - have you added maven
dependencies for these jars? (either compile scope, or system scope
if the jars only exist in the lib folder rather than from a maven repo)
embedded jars added to the class path? My understanding is that the
Bundle-ClassPath header is automatically generated from the dependencies
in the project's pom file. However, the embedded jar files are in the
yes but the Bundle-ClassPath is different to the compilation classpath,
it is more of a runtime definition - the bundle-plugin only starts its work
once maven has compiled the classes.
project directory, not in the maven repository. I'm pretty sure that my
class path isn't correct which is why the compiler can't find the
packages in the embeded jars.
I think you need to add something like the following for each lib jar:
<dependency>
<groupId>example</groupId>
<artifactId>example</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${basedir}/lib/example.jar</systemPath>
</dependency>
also, be aware that while embedded jars are visible to OSGi, they won't
be seen by the normal java compiler if you try to compile other sources
against your bundle (as javac doesn't handle embedded jars).
hope this helps.
