re. your exports also being imported - this is a specific feature of the Bnd Tool, see: http://www.osgi.org/blog/2007/04/importance-of-exporting-nd-importing.html as well as: http://aqute.biz/Code/Bnd#export-package which explains how to turn this off (add -noimport:=true as an attribute on the package) but importing your exports shouldn't cause any problems - on the contrary it solves them! Ignore-Package is just a 'helper/documentation' entry so you can see what packages the Bnd Tool ignored (same as the Include-Resource and Private-Package entries) these can be removed from the final bundle as the OSGi framework doesn't use them - if you want to remove them use the <_removeheaders> instruction, also documented on the Bnd site. the Bnd site also explains how Export-Package is processed (left to right) ... so to export your public API but not your implementation packages, use something like the following: <Export-Package>!deus.model.impl.*,deus.model.*"</Export-Package> <Private-Package>deus.model.impl.*</Private-Package> HTH Thanks a lot! > > Florian > --------------------------------------------------------------------- > To unsubscribe, e-mail: [email protected] > For additional commands, e-mail: [email protected] > -- Cheers, Stuart
