Re: [Neo4j] Spring Data Graph in an OSGi environment
Mmh, the question is if at least the exceptions and the TX abstract classes could be moved into exported packages. Still, instantiating implementation classes in the templates is probably the root of the problems. But then, as with pointing out implementations through the Java Service notion, somewhere we have to point out these things. We should probably go through these classes and determine the absolute minimum of public access that we need to expose in order to make this work. Meanwhile, if you change manifests and export the offending impl* pacakges, are things working out?

Re: [Neo4j] Spring Data Graph in an OSGi environment
In OSGi, missing classes can be down to which bundles are visible to
the bundle doing the scanning. In this case, whatever is doing the
classpath scanning cannot see the bundle exporting your domain package.
From a number of years back, I remember having to use
eclipse-registerbuddy to solve a classloader visibility issue. I'm not
sure what the standard approach to this became. A quick search doesn't
deliver anything definitive for bundle-buddypolicy, which I suspect is
the standardised mechanism.

I just could resove some more issues.
First of all I had to excplicitely add an Import-Package directive in
the template.mf of our project for packages that are not recognized by
bundlor (as the one for the missing Neo4jConfiguration):
Import-Package:
org.springframework.data.graph.neo4j.config;version=[1.1.0, 1.2.0),
org.springframework.data.repository.support;version=[1.0.0, 1.2.0),
org.springframework.transaction.aspectj;version=[3.0, 3.1)
I also had to put Import-Pacakge statements for cglib packages to the
spring data neo4j bundle.
The next problem I'm facing is that graph repositories cannot be
injected, because they seem not to be created by SDG:

Hi, I've written an article [1] showing how to run neo4j embedded database inside an OSGi container.

But when the spring application context is loaded, the class org.springframework.data.graph.neo4j.config.Neo4jConfiguration cannot be found during bean postprocessing and aspectj magic (see stacktrace below). The class is available and exported. I checked that with clhas and clexport on the Virgo console.
