Re: [Neo] Neo under OSGi
Hi Peter, Submitting patches would be a simple way to start, for now. I'll just use my own local snapshots of trunk until they get folded in. I'll use the keyword osgi on the trac tickets. For pax-exam tests, would you prefer a separate directory, like src/exam/java or a naming convention to distinguish integration tests from unit tests? -Andreas On Jul 7, 2009, at 1:54 AM, Peter Neubauer wrote: Hi Andreas, I have had that on my todo-list for quite a while but not really started that effort.

So, if you have patches or failing test cases, please send them to me and I will start a laboratory project to test OSGi things with the awesome OPS4J Pax Exam.

Re: [Neo] Neo under OSGi
Hi Andreas, thanks for your feedback! IMHO the OSGi-friendliness-projects should occur in two steps: 1. Make all jars OSGi - lib - friendly - see over the Manifest.mf for all components and check that we have all required OSGi Attributes in there - make sure there are no namespace clashes between Neo4j components, refactor where that occurs. 2. Provide a component that wraps and exposes the Neo4j APOC (http://wiki.neo4j.org/content/Getting_Started_With_Apoc) components services and public APIs in an OSGi bundle - introduce a new component, Neo4j-APOC-bundle - write an Actviator that instantiates and registers the main APOC services like EmbeddedNeo, IndexServices etc etc - provide ConfigAdmin integration for setting parameters, storage dirs etc etc and document it. - move the project out the the other components So, I think first, we should start a new laboratory component and get PaxExam up and running, pulling in more and more Neo4j bundles and fixing the problems as we go in the other components. Regarding APOC, it is a collection of useful Neo4j default components, and IMHO that is a good scope to start from. If people want to fine tune this and e.g. just expose EmbeddedNeo but not the Shell service, then we either might provide more bundles, more configuration at startup or they can look at the APOC bundle code and roll their own activators. WDYT? You are very welcome to start the process by submitting issues in TRAC, but as I said, I will be away for 2 weeks from Thursday, so I can chip in first afterward.

Re: [Neo] Neo under OSGi
Starting with the APOC-bundle to guide the transition and provide both a starting and reference point sounds really good to me. I'd be willing to get started with a nice pax-constructed project in labs, while you lounge away in Iceland. I'll try to time the biggest changes for when you're the least capable of paying attention ;) . How do I sign up?
