Christian,
I may suggest to look fist at the runtime configuration - it's possible
that there are two conflicting bundles exporting the same version of the
package.
I am attaching the list bundles from my runtime (eclipse launch
configuration).
Also it is always useful to make use of the equinox console for
analysis of the bundles, their content and state. I wasted a lot of
time before I discovered it.

Hi,
I have setup a little project with aries blueprint + jpa and
eclipselink (with aries.eclipselink.adapter). Backend is Derby
embedded driver. I have tree bundles, a datasource bundle for derby
(ch.eugster.herakles.datasource.derby), a jpa persistence bundle
(ch.eugster.herakles.persistence) with persistence.xml, orm.xml and
persistence classes (Tectonic, TectonicsLevel, TectonicsLevelLink) and
a junit test bundle (ch.eugster.herakles.persistence.test).
The testclass contains two testmethods so far, one checks if a
TectonicsService exists (testValidService) and a method that tries to
persist an object of type Tectonic (testPersist). Running the test,
the first method passes, but the second throws the following message:
[code]

I understand, that there is a classloader issue but I don't know why
it comes up and how I can resolve this problem. May anyone give me a
hint?
Thank you!
