ServiceMix 4 Integrating JBI with OSGi

Overview Recent releases Apache ServiceMix 3.2, 3.3 and 4.0.0 Dissecting ServiceMix 4.0.0 ServiceMix Kernel ServiceMix NMR and JBI Getting involved?

Recent releases Recent releases ServiceMix 3.2.x ServiceMix 3.3.x why separate components? ServiceMix 4.x why a new container?

ServiceMix 3.2.x ServiceMix 3.2.x JBI container and components in one release

ServiceMix 3.3.x ServiceMix 3.3.1 JBI Container version 3.3.1 JBI Components version 2009.01

ServiceMix 3.3.x – Component versioning Rationale for separate components versioning share component between ServiceMix 3.x and 4.x containers ensure container independence build using JBI API and shared library be able to test/run in both containers (as well as other JBI containers)‏ ease migration from 3.x to 4.x

ServiceMix 4.x ServiceMix 4.0.0 and beyond Modular OSGi-based container ServiceMix Kernel, ServiceMix NMR JBI Components version 2009.01

So what? We started with a JBI container and components... ...and we ended with one Why should I care?

ServiceMix NMR/JBI Using ServiceMix Kernel to build a JBI container We are using a 2 layer solution NMR API for messaging JBI specification implementation

ServiceMix NMR ServiceMix 4 NMR easy to use messaging API (Exchange, Message, Endpoint, ...)‏ handles XML and POJO payloads listener interfaces to monitor the NMR (ExchangeListener, EndpointListener, …)‏ support for wiring endpoints and intercepting exchanges command shell for managing the NMR

ServiceMix NMR ServiceMix 4 NMR installable as a ServiceMix Kernel feature You can use it for loosely coupled integration Camel routes CXF web services … add anything else yourself here We use it to build our JBI integration layer
