OSGi Tutorial#

I started a simple exercise (see OSGi In Practice above).

Starting with Eclipse Kepler, downloaded the Equinox runtime first from http://download.eclipse.org/equinox/. Unzip it to /usr/local/equinox-sdk-keplersr1.

Then add the Equinox named User Library to Eclipse, pointing to /usr/local/equinox-sdk-keplersr1/plugins/org.eclipse.osgi_3.9.1.v20130814-1242.jar .

Create a new Java project named "OSGi Tutorial", and make sure you use the above User Library.

Create a new runtime configuration, new Java Application, enter search this should find org.eclipse.core.runtime.adaptor.EclipseStarter and program arguments -console -configuration runtime. However, this does not work, you have to add the -consoleLog, or the (error) logging will go to a file by default.
