OSGi basicsCopyright VMware 2009, 2010. Licensed under the Eclipse Public License. 3Monday, 22 November 2010 3

“It’s bundles all the way down” • OSGi is a Module System A Bundle = a Jar file = a single module (approx) The Bundle Manifest defines the imports/exports • Many adopters including a lot of Eclipse projects • Defined by the OSGi AllianceCopyright VMware 2009, 2010. Licensed under the Eclipse Public License. 4Monday, 22 November 2010 4

Services • A Bundle can export and consume services This happens dynamically at runtime • A service is a Java Object with some properties • Managed by a Service Registry (the Whiteboard pattern)Copyright VMware 2009, 2010. Licensed under the Eclipse Public License. 5Monday, 22 November 2010 5

Life-cycle • Resolving the dependencies must happen before running a module’s code • starting/stopping/refreshing a module are life-cycle events • OSGi framework offers life-cycle management through services • modules are dynamic • resolved, started, stopped, refreshed at any timeCopyright VMware 2009, 2010.
