Re: Experimenting with Karaf 5
Hi Matteo, It sounds like a very interesting use case. Let me "push" K5 and merge the latest updates I did on the project. Thanks !

Re: Experimenting with Karaf 5
Thank you JB, I’ll set up a project in and I’ll open a PR as soon as it is (sort of ☺) working. There are couple of things we usually use in our apps such as weaving hook + byte-buddy and ConfigurationPlugins that will be interesting to test as well, but let us do one step a time.

Re: Experimenting with Karaf 5
Hi Matteo, You have two approaches to implement what you propose: - Karaf 4 style deployed in Karaf5: K5 OSGi application manager will deploy the Karaf4 features service, and so you can use the same thing as in K4. You will see K4 distribution in K5 doing that. - Karaf 5 style, you implement your own K5 SPI - you use another approach like CDI, Spring Boot I'm going to push K5 as a branch on the main Karaf repo. Anyway, you can submit your example directly on https://github.com/jbonofre/karaf5 (in an example module for instance) If you want, we can have a chat together about that. Thanks for your help anyway !

Experimenting with Karaf 5
Hello, I would like to start playing with Karaf5, waiting for the official RC... With the final goal of migrating a few OSGi 3-tier projects (Hibernate, Declarative Services, Apache CXF REST) to Karaf-5 my idea is: - Put together a very trivial JPA+CXF project using "Karaf-JPA-example" and "Karaf-rest-example" in Karaf's examples module - Create a feature for the complete "demo application" - Run this application in Karaf-5, deploying the application feature. The lesson learned will be used in the actual migration process. Before I start working head-down on this, I would like your advice: is this approach going to work with Karaf 5? Or is there any evident show-stopper I should be aware? Many thanks for your help. Best regards, Matteo
