This is a Heroku buildpack for OSGi apps. It uses Pax Runner 1.7.6 start the OSGi framework of choice and uses OpenJDK 1.6.0_20 to run it.

Example usage:

$ ls
paxrunner

$ heroku create --stack cedar --buildpack http://github.com/dennisg/heroku-buildpack-paxrunner.git

$ git push heroku master

The buildpack will detect your app as OSGi (using Pax Runner) if it has the file 'paxrunner' in the root. The file can be totally empty, it is just a marker file.

The Pax Runner distribution is unpacked inside your slug directory in '.buildpack'. A Procfile is not required, because the buildpack supplies a (I think) reasonable default.

Default Procfile:

web: pax-run.sh --platform=${OSGI_FW} --version=${OSGI_VER} --console=false --vmo="-Dorg.osgi.service.http.port=$PORT" $PROVISIONING_URL

where OSGI_FW=felix, OSGI_VER=4.0.2, PORT supplied by Heroku and PROVISIONING_URL=scan-dir:bundles. This means that the default setup will start up an OSGi framework based on Felix, version 4.0.2 starting all bundles in 'bundles'.

Modifying the default OSGi framework is as simple as this:

heroku config:add OSGI_FW=equinox
heroku config:add OSGI_VER=3.7.0

Provisioning URL

You can also simply change the provisioning url that is required for your slug

heroku config:add PROVISIONING_URL=scan-dir:data (or any other valid provisioning url)

For more info on the various forms of provisioning urls: Pax Runner Docs

Example Custom Procfile:

web: pax-run.sh --platform=equinox --console=false --vmo="-Dorg.osgi.service.http.port=$PORT" $PROVISIONING_URL
