Geronimo uses Karaf as the OSGi framework and comes with both Equinox and Felix pre-installed as runtime. You can easily configure the OSGi environment by updating .properties
files under /etc
directory. By default, Geronimo server uses Equinox as its default OSGi runtime. The following is a list of simple tasks for your demonstration.
Changing the OSGi runtime
The config.properties
file is the system properties file of underlying OSGi framework of Geronimo, in which stores the initial configuration parameters to start up a Karaf framework.
- Open
config.properties
file under/etc
directory. - Uncomment the line with karaf.framework=equinox and comment out the line with karaf.framework=felix.
- Specify the location of Flex bundle using the key karaf.framework.felix. The following code snippet is an updated
config.properteis
file.config.properties... # # Framework selection properties # # karaf.framework=equinox karaf.framework=felix karaf.framework.felix=repository/org/apache/felix/org.apache.felix.framework/3.0.2/org.apache.felix.framework-3.0.2.jar ...
- Save the file and restart the server.
See Apache karaf for more information about those key=value pairs in the config.properties
file.
Enabling OSGi framework debugging
The equinox-debug.properties
is used to configure debug options for Equinox runtime. To enable debug for the Equinox runtime.
- Open
config.properties
file under/etc
directory. - Comment out the line with *osgi.debug=$
Unknown macro: {karaf.home}/etc/equinox-debug.properties
/etc/equinox-debug.properties*.
- Update value of each parameter in the
equinox-debug.properties
file as needed. The following code snippet is an updatedconfig.properteis
file....config.properties
# - Debug options for Equinox
#
osgi.debug=$
... - Update value of each parameter in the
- Save the file and restart the server.
