Hi Peter,
Thanks for initiating this work on OSGi bundle.
I've forked you repository and tried to make is work using this sample
activator [1]. My goal is to make my activator work when deployed on Felix with
the neo4j superbundle.
First of all, I had troubles to mvn clean install the bundle module.
maven-bundle-plugin is complaining about bundle.namespace property not set.
I've fixed it.
Then when deploying it on Felix I had an error saying that javax.transaction
couldn't be imported. Because this package is already included in superbundle,
I've removed it explicitally from the Import-Package directive. You can see the
changes here [2].
Then I tried to make my bundle activated using felix and the following bundles
installed :
g! lb
START LEVEL 1
ID|State |Level|Name
0|Active | 0|System Bundle (3.2.2)
1|Active | 1|Neo4j OSGi default bundle (0.1.0.SNAPSHOT)
2|Active | 1|Apache Felix Bundle Repository (1.6.2)
3|Active | 1|Apache Felix Gogo Command (0.8.0)
4|Active | 1|Apache Felix Gogo Runtime (0.8.0)
5|Active | 1|Apache Felix Gogo Shell (0.8.0)
6|Resolved | 1|EscapeK - Neo4j OSGi how-to - Embedded client
(0.0.1.SNAPSHOT)
There are only felix core, neo4j superbundle and my test bundle.
So when starting felix I get the following trace :

So everything works fine (open database, populate it and register service)
until the activator tries to register IndexProvider service. I then get the
previous exception which reminds me of something ...
May be you can have a look at the stack trace to look for the error cause.
