Overview

Apache ServiceMix Kernel is a small OSGi based runtime which provides a lightweight container onto which various components and applications can be deployed.

Here is a short list of features supported by the Kernel:

Hot deployment: ServiceMix Kernel supports hot deployment of OSGi bundles by monitoring jar files inside the [home]/deploy directory. Each time a jar is copied in this folder, it will be installed inside the runtime. You can then update or delete it and changes will be handled automatically. In addition, the Kernel also supports exploded bundles and custom deployers (a spring one is included by default).
Dynamic configuration: Services are usually configured through the ConfigurationAdmin OSGi service. Such configuration can be defined in ServiceMix Kernel using property files inside the [home]/etc directory. These configurations are monitored and changes on the properties files will be propagated to the services.
Logging System: using a centralized logging back end supported by Log4J, ServiceMix Kernel supports a number of different APIs (JDK 1.4, JCL, SLF4J, Avalon, Tomcat, OSGi)
Provisioning: Provisioning of libraries or applications can be done through a number of different ways, by which they will be downloaded locally, installed and started.
Native OS integration: ServiceMix Kernel can be integrated into your own Operating System as a service so that the lifecycle will be bound to your Operating System.
Extensible Shell console: ServiceMix features a nice text console where you can manage the services, install new applications or libraries and manage their state. This shell is easily extensible by deploying new commands dynamically along with new features or applications.
Remote access: use any SSH client to connect to the kernel and issue commands in the console
Security framework based on JAAS
Managing instances: ServiceMix Kernel provides simple commands for managing instances of ServiceMix Kernel. You can easily create, delete, start and stop instances of ServiceMix Kernel through the console.

ServiceMix Kernel 1.0.0

We're very please to announce the availability of Apache ServiceMix Kernel 1.0.0.

This release is the first GA release of ServiceMix Kernel. A few bugs and enhancements have been done to the Kernel since the second release candidate. The most two important fixes from a user point of view are SMX4KNL-70 which makes sure the bundles provided in the distribution are used first instead of the ones from the user's local maven repository and SMX4KNL-77 which allows artifacts in the /deploy folder to be started when the needed dependencies have been installed successfully (the previous behavior was to fail if there were missing bundles when the artifact is processed).

A more detailed change log and download links are available on ServiceMix Kernel 1.0.0.

The main change is that the system folder that contains the OSGi bundles to install in the runtime is now
organized as a maven 2 repository, though it should not directly affect users.
