I could manage it to run my test code with Equinox Helios (Eclipse 3.6) which
implements OSGi spec 4.2 (*< 4.3*):
This leads to a BundleException for OpenCMIS OSGi Client Wrapper as assumed
above (cause of missing *.wiring package).
This is no problem for me in my environment (probably no problem for most OSGi
clients) but I wanted mention it.
>From my point of view you can resolve this issue *jippiee* ;)
> Allow loading classes from other OSGi Bundles in OSGi Client Wrapper

> Key: CMIS-878
> URL: https://issues.apache.org/jira/browse/CMIS-878
> Project: Chemistry
> Issue Type: Improvement
> Components: opencmis-client
> Affects Versions: OpenCMIS 0.12.0
> Environment: OSGi
> Reporter: Sascha Homeier
> Assignee: Florian Müller
> Priority: Minor
>
> When using the OpenCMIS OSGi Client Wrapper it is hard to load classes from
> other bundles. For example if you specify an own Authentication Provider
> class as Session Parameter then the Wrapper will not find this class when it
> is located inside another bundle. Same problem should occur when defining an
> own Cache.
> *1)*
> It would be nice if other bundles could register their Classloaders so that
> ClassLoaderUtil can use it when trying to load classes.
> *2)*
> Another simpler option would be to simply add "DynamicImport-Package: *" to
> the Manifest of the Wrapper. By doing this the Wrapper will find all classes
> which are exported by other bundles. Though this approach feels more like a
> hack since it breaks modularity.
> What do you think about it?
> Cheers
