Just me two cents. When karaf will be capable to deploy multiple artifacts as applications (apache aries applications) or something like that it can use eclipse virgo's par approach. Here is the link: http://www.eclipse.org/virgo/documentation/virgo-documentation-2.1.0.RELEASE/docs/virgo-programmer-guide/html/ch04s02.html Quotation: The artifacts of a PAR have their exported packages imported by the synthetic context bundle which is used for thread context class loading. So, for example, hibernate will be able to load classes of any of the exported packages of the artifacts in a PAR file using Class.forName() (or equivalent). Moreover PAR applications have some more useful features.

As Richard said, there's no easy way to solve the problem. What we've done in Karaf / Servicemix / Camel where needed is that when using a library that require a TCCL to be set for finding classes or resources, we set it locally before calling that library. A cleaner API would be to actually pass a classloader directly (JaxbContext does that for example IIRC), but it's basically the same: the caller needs to build / find the classloader, so it does not really change anything.
