Hi Jamie, I followed your guide and I think it's great :).
Below are some minor comments: 1. You could base your Maven assembly descriptor on the ones that are avilable in the Apache Felix project. This would eliminate the need to change the existing sections of config.properties and startup.properties. See: http://svn.apache.org/viewvc/karaf/trunk/assembly/src/main/descriptors/unix-bin.xml?revision=958856&view=markup 2. Unfortunately, the released version of Apache Aries (0.1-incubating) uses Derby DB with disk storage. This complicates your quide a bit. The version of samples that is available in the trunk uses in-memory DB. I think that it would make sense to update your guide when a new version of Aries is released. 3. Warnings related to namespace handlers are ok. All shell commands are initialized eventually by the Blueprint Extender. 4. Maybe you could also provide a package with a fully working solution? It would be really useful for those wanting to take the shortest path possible. :) Best regards, Bartek 2010/7/4 Valentin Mahrwald <[email protected]>: > Very nice! > > I followed it all the way through and except for a small race condition > between the blog datasource service registration and the jpa extender > creating the EntityManager everything worked like a charm.
