The OSGi subsystem is configured like any other subsystem in the standalone/domain XML descriptor. The configuration options are:
Subsystem Activation - By default the OSGi subsystem is activated on-demand. The activation attribute can be set to 'eager' to initialize the subsystem on server startup.
Framework Properties - OSGi supports the notion of framework properties. Property values are of type string. A typical configuration includes a set of packages that are provided by the server directly. Please refer to the OSGi core specification for a list of standard OSGi properties.
Module Dependencies - The Framework can export packages from server system modules. The property 'org.jboss.osgi.system.modules.extra' contains a list of module identifiers that are setup as dependencies of the OSGi Framework.
Capabilities - OSGi bundles can be installed by providing coordinates to the OSGi Repository. Supported coordinates include but are not limited to Maven coordinates and module identifiers.
Config Admin properties - Supported are multiple configurations identified by persistent id (PID). Each configuration may contain multiple configuration key/value pairs.Below is a sample configuration for the OSGi subsystem
