The core Vaadin jar is a valid OSGi bundle but creating a Vaadin OSGi application can be a daunting task. This package contains a bundle which allows Vaadin apps to be deployed as OSGi Declarative Service components, a bundle which proxies resources from the core Vaadin bundle (though static resource deployment to a web-server is recommended) and a sample application. Please see the README.txt in the zip for more information and each bundle contains it's own source code. Note: See the discussion thread for instructions on how to get started with Felix.
