Introduction to OSGi
What does OSGi stand for?
• Open Services Gateway initiative
  – This abbreviation is no longer used
• “The Dynamic Module System for Java”
  – Designed to be light weight and dynamic
  – Allows to partition a system into a number of modules
    (a.k.a. bundles)
  – Strict visibility rules (similar to private and protected)
  – Resolution of dependencies and versioning
  – Dynamic Modules can be installed, started, stopped,
    uninstalled and updated - all at runtime
What is the OSGi Service Platform
• A Java framework for developing remotely deployed
  service applications, that require:
   – Reliability
   – Large scale distribution
   – Wide range of devices
   – Collaborative
• Created through collaboration of industry leaders
• Spec 4.0+ publicly available at www.osgi.org
OSGi Environment
                                             Bundle
                                                Bundle
                                                   Bundle
      = service interface
      exported and imported                  Bundle (Application/Service)
      by bundles



                                    OSGi
•Open standard and based on Java
•Sits on top of the operating
system (thus is OS independent)               Java VM
•Not device or CPU specific.
•Client-server software                               Operating System

                                                      Hardware
OSGi Framework
• Allows applications to share a single Java VM
• Manages applications
  – Life cycle, Java Packages, Security, Dependencies
    between applications
• Service registry for collaboration
• Extensive notification mechanism
OSGi Bundles
• OSGi specification defines the OSGi as the unit
  of modularization
• A bundle is
  – Cohesive
  – Self-contained unit
     • Defines dependencies to other modules/services
     • Explicitly defines its external API (interface)
  – A jar file with additional meta information stored
    in the MANIFEST.MF file
MANIFEST.MF File


Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Popup Plug-in Bundle-SymbolicName:
de.vogella.rcp.intro.commands.popup; singleton:=true
Bundle-Version: 1.0.0 Bundle-Activator: de.vogella.rcp.intro.commands.popup.Activator
Require-Bundle: org.eclipse.ui, org.eclipse.core.runtime
Bundle-ActivationPolicy: lazy
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Cooperative Model
• Bundles can cooperate through:
  – service objects
  – package sharing
• A dynamic registry allows a bundle to find and
  track service objects
• Framework fully manages this cooperation
  – Dependencies, security
Service Specifics
• A service is an object registered with the
  Framework by a bundle to be used by other
  bundles


                 service
• The semantics and syntax of a service are
  specified in a Java interface
Services & Java Interfaces
                                                public interface Log {
                                                  public void log(String s);
                                                }
              Gets from Framework
                                                            interface
              (with query)
    Bundle                                Log


public class SimpleLog implements Log {
  public void log(String s) {
    System.out.println( s );                       implements
  }
}


                         Simple           IBM         Motorola
                          Log             Log          Log
Dependencies
• The Framework manages the dependencies
  between bundles
• Bundles that are installed and started will
  register services
• Framework will automatically unregister
  services when a bundle stops
• Event notifications for all important events
Dependencies
   Install A
                                             Framework


 start                      Bundle A
                               {}
                                                         Bundle B
                                                           {}
   events: install


= service, java interface              Bundle C
                                          {}
Dependencies
                                               Framework

Uninstall
 stop                         Bundle A
                                 {}
                                                           Bundle B events:
                                                             {}     unregister
    events: uninstall


  = service, java interface              Bundle C
                                            {}
The Classpath in OSGi
• Each bundle has its own class loader
• Bundles can only shares packages when:
   – Import and export clauses in the manifest match
   – Have permission to do so for those packages
• The framework manages the overall CLASSPATH for
  bundles
• Assures that all bundles use the same class (of the same
  version)
• Tracks shared usage of packages between bundles
Key OSGi Features
• Modularization
• Dynamic Runtime
• Service Orientation
What problems does OSGi solve?
• Visibility By default, a bundle is a black box.
  It's completely protected and you can't see
  inside it, not even with reflection or any other
  classloading trickery. Only exported packages
  are visible outside of the exporting bundle.
  This stops unintended coupling between
  modules, enables independent development,
  faster development cycles and security.
What problems does OSGi solve?
• Operational Control
  An OSGi container allows you to see all modules
  and their status - using the OSGi console or JMX.
  You can get information on wiring, install new
  bundles, activate bundles (and publish services),
  deactivate bundles (and unregister services),
  refresh bundles, stop bundles and uninstall
  bundles. The beauty? You can do all of this
  without stopping or restarting the application!
Who doing OSGi containers?
• Open-source implementations: Equinox, Felix
  (Apache), Knopflerfish
• Significant Enterprise usage: Eclipse,
  Netbeans, IBM (WebSphere), Red (Jboss),
  Oracle (Glassfish, WebLogic), TIBCO ESB,
  WSO2 Carbon, Fuse ESB…
Who’s doing frameworks?
• Hitachi provides a complete OSGi solution yet with standards
  compliant and potentially independent elements (only vendor
  with all 4 elements):
   1.       JVM Options (to insure broadest availability of ported JVMs and
            optimized JVMs):
        •      SuperJEngine (optimized CVM) (better performance, less memory, non-
               open source)
        •      or Oracle Binary solutions: CDC JVM or JavaSE Embedded (reduce risk; add
               value)
   2.       SuperJFramework (client software) (performance, less memory,
            not open source)
        •      SuperJManagement Agent (links to SJDMS) (meets SPs authentication &
               security)
   3.       SuperJDMS (Management Server) (manage clients/bundles/apps
            in device; large scale)
   4.       SuperJTools (SDK development tools for 3rd party apps) (Eclipse
            based)

  • 12. OSGi DevCon • For more information : http://www.osgi.org/DevCon2012/HomePage
  • 14. What does OSGi stand for? • Open Services Gateway initiative – This abbreviation is no longer used • “The Dynamic Module System for Java” – Designed to be light weight and dynamic – Allows to partition a system into a number of modules (a.k.a. bundles) – Strict visibility rules (similar to private and protected) – Resolution of dependencies and versioning – Dynamic Modules can be installed, started, stopped, uninstalled and updated - all at runtime
  • 15. What is the OSGi Service Platform • A Java framework for developing remotely deployed service applications, that require: – Reliability – Large scale distribution – Wide range of devices – Collaborative • Created through collaboration of industry leaders • Spec 4.0+ publicly available at www.osgi.org
  • 16. OSGi Environment Bundle Bundle Bundle = service interface exported and imported Bundle (Application/Service) by bundles OSGi •Open standard and based on Java •Sits on top of the operating system (thus is OS independent) Java VM •Not device or CPU specific. •Client-server software Operating System architecture Driver Driver Driver Hardware
  • 17. OSGi Framework • Allows applications to share a single Java VM • Manages applications – Life cycle, Java Packages, Security, Dependencies between applications • Service registry for collaboration • Extensive notification mechanism
  • 18. OSGi Bundles • OSGi specification defines the OSGi as the unit of modularization • A bundle is – Cohesive – Self-contained unit • Defines dependencies to other modules/services • Explicitly defines its external API (interface) – A jar file with additional meta information stored in the MANIFEST.MF file
  • 19. MANIFEST.MF File Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: Popup Plug-in Bundle-SymbolicName: de.vogella.rcp.intro.commands.popup; singleton:=true Bundle-Version: 1.0.0 Bundle-Activator: de.vogella.rcp.intro.commands.popup.Activator Require-Bundle: org.eclipse.ui, org.eclipse.core.runtime Bundle-ActivationPolicy: lazy Bundle-RequiredExecutionEnvironment: JavaSE-1.6
  • 20. Cooperative Model • Bundles can cooperate through: – service objects – package sharing • A dynamic registry allows a bundle to find and track service objects • Framework fully manages this cooperation – Dependencies, security
  • 21. Service Specifics • A service is an object registered with the Framework by a bundle to be used by other bundles service • The semantics and syntax of a service are specified in a Java interface
  • 22. Services & Java Interfaces public interface Log { public void log(String s); } Gets from Framework interface (with query) Bundle Log public class SimpleLog implements Log { public void log(String s) { System.out.println( s ); implements } } Simple IBM Motorola Log Log Log
  • 23. Dependencies • The Framework manages the dependencies between bundles • Bundles that are installed and started will register services • Framework will automatically unregister services when a bundle stops • Event notifications for all important events
  • 24. Dependencies Install A Framework start Bundle A {} Bundle B {} events: install = service, java interface Bundle C {}
  • 25. Dependencies Framework Uninstall stop Bundle A {} Bundle B events: {} unregister events: uninstall = service, java interface Bundle C {}
  • 26. The Classpath in OSGi • Each bundle has its own class loader • Bundles can only shares packages when: – Import and export clauses in the manifest match – Have permission to do so for those packages • The framework manages the overall CLASSPATH for bundles • Assures that all bundles use the same class (of the same version) • Tracks shared usage of packages between bundles
  • 27. Key OSGi Features • Modularization • Dynamic Runtime • Service Orientation
  • 28. What problems does OSGi solve? • Visibility By default, a bundle is a black box. It's completely protected and you can't see inside it, not even with reflection or any other classloading trickery. Only exported packages are visible outside of the exporting bundle. This stops unintended coupling between modules, enables independent development, faster development cycles and security.
  • 29. What problems does OSGi solve? • Operational Control An OSGi container allows you to see all modules and their status - using the OSGi console or JMX. You can get information on wiring, install new bundles, activate bundles (and publish services), deactivate bundles (and unregister services), refresh bundles, stop bundles and uninstall bundles. The beauty? You can do all of this without stopping or restarting the application!
  • 30. Who doing OSGi containers? • Open-source implementations: Equinox, Felix (Apache), Knopflerfish • Significant Enterprise usage: Eclipse, Netbeans, IBM (WebSphere), Red (Jboss), Oracle (Glassfish, WebLogic), TIBCO ESB, WSO2 Carbon, Fuse ESB…
  • 31. Who’s doing frameworks? • Hitachi provides a complete OSGi solution yet with standards compliant and potentially independent elements (only vendor with all 4 elements): 1. JVM Options (to insure broadest availability of ported JVMs and optimized JVMs): • SuperJEngine (optimized CVM) (better performance, less memory, non- open source) • or Oracle Binary solutions: CDC JVM or JavaSE Embedded (reduce risk; add value) 2. SuperJFramework (client software) (performance, less memory, not open source) • SuperJManagement Agent (links to SJDMS) (meets SPs authentication & security) 3. SuperJDMS (Management Server) (manage clients/bundles/apps in device; large scale) 4. SuperJTools (SDK development tools for 3rd party apps) (Eclipse based)
