In case you are using eclipse: There is a wizard for that. It allows you to select a number of jar libraries and creates a plug-in project (i.e. OSGi bundle) including these jars. You can find it here: File -> New -> Other … -> Plug-in from Existing jar Archives.
The error means that your bundle has a Require-Capability: osgi.ee; filter=”(&(osgi.ee=JavaSE)(version=1.8))” entry in its manifest. So this means the bundle will only start when there is a bundle that provides this capability. In case of the osgi.ee capability it is the OSGi framework (equinox) that should provide this capability. Apparently it does not do this. … Read more
Option 1 – use bnd-platform to build your OSGi bundles when expecting frequent additions/updates of Jars, or when you can retrieve your dependencies from Maven repositories We use bnd-platform (I am also the author) to manage third party dependencies and create OSGi bundles from them. You can use it with both dependencies retrieved from Maven … Read more
Follow the article Create Eclipse plugins (OSGi bundles) from standard jar to achieve this. Though this approach does not use Bnd, but you would be able to achieve what you want. In short you can do following: Create a new Plugin project by selection File-> New -> Project…-> Plug-in Development -> “Plug-in from Existing JAR … Read more
I believe Require-Bundle is an Eclipse thing (that has now made it in the OSGi spec to accommodate Eclipse). The “pure” OSGi way is to use Import-Package, as it specifically decouples the package from the bundle that provides it. You should be declaring dependencies on functionality that you need (the Java API provided by a … Read more
This is a long answer, the quick answer for the impatient is to download this sample code for displaying a splash page for an intensive startup task and see if it is adaptable to your situation. My answer provides general information about Preloader style functionality in JavaFX. Your question specifically mentions Preloader usage in an … Read more
Any OSGi framework (R4.1 or later) can be started programmatically using the FrameworkFactory API: ServiceLoader<FrameworkFactory> ffs = ServiceLoader.load(FrameworkFactory.class); FrameworkFactory ff = ffs.iterator().next(); Map<String,Object> config = new HashMap<String,Object>(); // add some params to config … Framework fwk = ff.newFramework(config); fwk.start(); The OSGi framework is now running. Since Framework extends Bundle you can call getBundleContext and call … Read more
what benefits does OSGi’s component system provide you? Well, Here is quite a list: Reduced Complexity – Developing with OSGi technology means developing bundles: the OSGi components. Bundles are modules. They hide their internals from other bundles and communicate through well defined services. Hiding internals means more freedom to change later. This not only reduces … Read more
You can do one of two things: Call getResources() and iterate through the returned collection of URLs, reading them as manifests until you find yours: Enumeration<URL> resources = getClass().getClassLoader() .getResources(“META-INF/MANIFEST.MF”); while (resources.hasMoreElements()) { try { Manifest manifest = new Manifest(resources.nextElement().openStream()); // check that this is your manifest and do what you need or get the … Read more
