Hi In general it is good practive in OSGi to import everything you export. but in this case I guess it could be a private-package to just tie jena to its preferred xerces bundle.
You're very welcome to submit a patch maybe also updating the jena version :) Cheers, Reto On Fri, Dec 7, 2012 at 12:00 PM, Minto van der Sluis <mi...@xup.nl> wrote: > Thanks for your reply. > > See my remarks below > > Regards, > > Minto > > Op 7-12-2012 11:37, Daniel Spicar schreef: > > I am not sure what is happening but it is possible that Xerces is > confused > > because it somehow found conflicting class definitions. > > > > Regarding "org.apache.clerezza.ext:com.hp.hpl.jena.tdb": > > > > I don't know why it imports 'xerces.util' but > > 'org.apache.clerezza.ext:com.hp.hpl.jena.tdb' is an 'osgi-ified' Jena TDB > > (presumably an old version).
