I am an Open Source Architect at Talend working full time on the Apache projects Camel, CXF and Karaf. On my blog you will find the latest news from the Open Source communities I work in. I also write tutorials about OSGi, services and integration.
Best practices for Services and Integration in OSGi (WJAX 13)
In this talk from WJAX 2013 I show best practices for OSGi development in a practical example based around an online voting application.
Apache Karaf Tutorial Part 8 - Distributed OSGi
By default OSGi services are only visible and accessible in the OSGi container where they are published. Distributed OSGi allows to define services in one container and use them in some other (even over machine boundaries).

ApacheCon Talk OSGi best practices shown on Apache Karaf
I just did my ApacheCon talk about OSGi best practices.It was the last slot but the room was still almost full. In general the OSGi track had a lot of listeners and there were a lot of talks that involved Apache Karaf. So I think that is a nice sign for greater adoption of OSGi and Karaf.

Integration ganz einfach mit Apache Camel
Nach dem Talk auf der letzten W-JAX hatte ich nun die Gelegenheit, auch auf der JAX über Apache Camel zu sprechen. Diesmal hatte ich einen grösseren Raum zur Verfügung, der mit fast 200 Zuhörern auch gut gefüllt war. Dies zeigt das grosse Interesse an Apache Camel. Die Präsentation ist direkt im Anhang verfügbar. Diesmal ging ich stärker auf OSGi und Apache Karaf als Ablaufumgebung ein. Ich hatte auch nur 20 Folien und verwendete einen größeren Teil der Zeit für Live Demos. …

Camel and JMS on JBoss
Camel has many options for deployment. If I have the freedom of choice I prefer to run Camel on Karaf but the typical case at customers is that they have a certain app server and we have to fit in. In this case the platform was JBoss 5.1. Before Camel 2.8 this was quite complicated as camel tried to scan for typeconverters on the classpath and that part failed because of the JBoss class loader. I used camel 2.8.4 and so this was no issue except for a little problem I will come back to later. …
Big improvements for CXF in OSGi ahead with version 2.6.0
CXF 2.6.0 will bring a lot of improvements for deployment in OSGi. Till now cxf was bundled in one OSGi bundle. Either with all features or with a minimal feature set. Thanks to Dan Kulp cxf is now delivered as individual bundles. So it can be installed with only the needed features. Besides the smaller size in many use cases this also means that we have less optional dependencies which make installation difficult. Each bundle defines the imports it really needs. …
