Okay, this is very enlightening. So in my case of creating an H2
database module:
1) A few packages have compile time only dependencies...unless the H2
deployment specifically uses those 3rd party features (e.g.,
org.lucene). So, this is what you refer to as an optional dependency
right?
2) Is there an "optional" flag for the <Import-Package> section or
some other way to declare org.lucene as optional.
3) If I declare lucene optional and don't package it, but then the
user does wants to use the lucene features, I need to instruct them to
add the package to the proper vm sections(s) of the conf/
config.properties file? Or is their some other way?
Thanks!

I would recommend option (b), since (a) hides the dependency, which
will cause your bundle to fail on other frameworks or even
misconfigured installations of Felix and you won't easily know why.
Better to have your dependencies be explicit, so that people will
know how to satisfy them.

That did the trick! I just removed the imports using option a.
Now I have to look at what makes since in separating the current
bundle into separate services: tcp server, embedded server, mixed
mode, web console etc. What I'm really interested in is deploying
in mixed mode (embedded and tcp db server) to get the in-vm speed
advantages but still connect from external tools. Using felix I can
do that now and deploy multiple services that take advantage of an
embedded db.
Thanks again!

The issue is that the packages are not exported by the system
bundle.
You can do one of the following two things:
a) remove the import from your bundle i.e.,
<Import-Package>
!., !com.sun.*, !sun.*,*
</Import-Package>
and add/uncomment the following line in conf/config.properties
org.osgi.framework.bootdelegation=sun.*,com.sun.*
or b) add the required packages to the system bundle exports. That
can
be done in the conf/config.properties as well by adding it to the
Java
platform package export properties. Make sure you add it to the list
that matches your version of java.
It's hard to say which approach is preferable - there are pro and
cons
to both. Are you sure your bundle really needs the packages or is it
an optional dependency? Maybe just remove the import and don't add
the
bootdelegation line. Then see whether your bundle does run without
access to the packages. If that is the case go with option b) but
mark
the import as optional.

I'm new to osgi/felix and am trying to wrap h2 database as an
iPOJO bundle.
When starting the service from felix console I get:
"org.osgi.framework.BundleException: Unresolved package in
bundle 24:
package; (package=com.sun.tools.javac)"
I'm on Mac OS X 10.5 (Leopard) which, to my understanding,
includes this
package in the runtime. So there is no tools.jar that needs to be
imported.
Any ideas how to get this working?
Thanks!
