HTTP & OSGiRequirements:o Grouping (“application”)o Multi-tenancy o Run multiple instances of an “application” on different URLs

HTTP & OSGipublic class MyWebApp extends Application { @Override protected void doInit() throws CoreException { getApplicationContext().registerServlet(…); getApplicationContext().registerResources(…); getApplicationContext().registerFilter(…); }}

HTTP & OSGiosgi> http <cmd> [args] ls … lists registered applications or providers defineApp … defines an application removeApp … removes an application definition setAppProperty … sets/removes an application property mount … mounts an application at the specified URL unmount … unmounts the specified URL start … starts an application stop … stops an application

Queue ServiceIQueueService { IQueue getQueue(..)}IQueue { void sendMessage(byte[] messageBody) List<IMessage> receiveMessages(..) IMessage consumeMessage(..) boolean deleteMessage(..)}
