OSGi Bundles

The REQUEA Platform is based on OSGi. That means:

- applications are packages as OSGi bundles that can be deployed on the platform
- the platform itself is packaged as bundles
- bundles can be added to extend the applications or the platform.

Structure of an OSGi bundle

A bundle is a jar file with a manifest. It provides:

- a symbolic name, which is the identifier of the bundle
- a version number
- a classpath entry that describes java classes that can be loaded by the platform
- dependencies. This is useful to describe which services or classes or even bundles are required by the bundle.

The list of bundles that the platform has started is available on the dysoweb panel:

http://localhost:8080/dysoweb/dysoweb/panel/secure/bundles.jsp
