Knopflerfish is a leading universal open source OSGi Service Platform. Knopflerfish implements it's own OSGi framework as defined by the OSGi Core Specification and a o a large set of the bundles / services defined by OSGi Compendium Specification. Knopflerfish also includes various optional services such as OSGi wrappers for popular 3rd party libraries, knopflerfish specific bundles / services, and utilities and development tools.
Knopflerfish is designed to be compliant with the OSGi Release 6 specifications.
The Knopflerfish website has the full documentation and Knopflerfish OSGi Service Platform SDK's available for download. http://www.knopflerfish.org
Building Knopflerfish OSGi
- JDK 6 or later, available from Open JDK, Oracle or elsewhere.
- Ant 1.9.1 or later, available from ant.apache.org.
- openssl, to create and manipulate certificates when using security and the Conditional Permission Admin (CPA) service. Test suites for CPA can not be built and executed without openssl.
- ProGuard 4.10 or later, tested with 5.2. This is only need if you want to build the compact version of the framework. You need ProGuard 5 or later if you want to build with Java 8.
Knopflerfish, release 6, is designed to run on Java 1.6 and upwards.
The Knopflerfish 6 SDK releases are always compiled with JDK6.
The Knopflerfish SDK can however be rebuilt for another JDK versions if preferred. For a comprehensive explanation of running and building Knopflerfish with different JDK versions please consult: http://www.knopflerfish.org/osgi_java_compatibility_guide.html
How to build
Clone this repository
Step into the osgi subdir and call ant
> cd osgi > ant
This will build the framework and all essential OSGi bundles.
After a successful build a
framework.jar will be created.
Compiled bundles are placed in the
To start the platform simply run:
java -jar framework.jar
To get more start-up options:
java -jar framework.jar -help
Please refer to the documentation for a complete description on starting Knopflerfish and start options.
Building the Knopflerfish OSGi SDK
A complete Knopflerfish OSGi SDK distribution can also be built. In this case build from the root directory of the repo and call the distrib target:
This target will compile all bundles, including test bundles. run the knopflerfish test suite, generate javadoc and bundle specific documentation, and finally create a self-extracting jar file with the complete SDK.
Working with bndtools
Knopflerfish itself is not built with bnd or bndtools, but it is very easy to integrate or use knopflerfish since an OSGi repository index file is generated in the build process.
Insert the following in the .bnd file of your project.
-plugin.org.knopflerfish.kf6: \ aQute.bnd.repository.osgi.OSGiRepository; \ locations=http://www.knopflerfish.org/releases/6.1.0/osgi/jars/index.xml; \ name=kf6
and replace the location with a file URL pointing to your local Knopflerfish repository.
Working with maven
During the distribution build a maven2 repository is built which can be used as a local maven repository.
More information on user maven can be found here: http://www.knopflerfish.org/maven.html
