Transcript

  • 1. All About Virgo Christopher Frost – Virgo Committer Martin Lippert – Lead, Spring Development Tools SpringSource, a division of VMware 3rd November 2011 OSGi Alliance Marketing © 2008-2010 . All Rights Reserved Page 1
  • 2. Page 2 First Hands up if you have used Virgo before?
  • 3. Page 3 Agenda • Back to basics, Virgo Catch up • What's new • Tooling • Snaps • Regions • The Future
  • 4. Page 4 Virgo – Catch up To be the best OSGi runtime environment we can be ● OSGi as the programming model ● Standards compliant ● Simplifies the managing Enterprise OSGi ● Simplifies the use of existing containers
  • 5. Page 5 Virgo – Catch up
  • 6. Page 6 Virgo 3.0 – What's new • Regions have replaced Nested Frameworks • New Shell based on Apache GoGo • Spring 3.0.5.RELEASE & Equinox Indigo • Declarative Service & Log Service support
  • 7. Page 7 Virgo 3.0 – Regions
  • 8. Page 8 Virgo 3.0 – Demo The GoGo Shell & Regions For more about GoGo see Fridays Talk “Next Generation Equinox Shell”
  • 9. Page 9 Virgo 3.0 – What's new • Servlet 3.0 with Tomcat 7.x • Gemini.Web, strict compliance to OSGi web container spec • Jetty version (based on 7.x) • Updated sample application, Greenpages • Lots of Bugfixes etc...
  • 10. Page 10 Tooling - History dm Server Tooling becomes Virgo IDE
  • 11. Page 11 Tooling • Bundle and PAR projects • Including Bundlor • PDE-like editors • Server integration • Launching • Deployment • Introspection • EBR – Enterprise Bundle Repository
  • 12. Page 12 Tooling – Demo Virgo IDE
  • 13. Page 13 Virgo 3.0 – What's new Snaps gets its first release • Some features tidied up • Documentation written • Single sample app showing everything Snaps can do • All available in a Zip from the Virgo website
  • 14. Page 14 Snaps – Basics • Lots of Snaps (Web Application Bundles) • Snaps have the hosts ServletContext • Uses a filter to dispatch requests from the host • Everything else is business as normal
  • 15. Page 15 Snaps – Nested Context Paths /app/orders /app/billing
  • 16. Page 16 Snaps – A filter for Snaps • Still just web.xml • Define the subpath for Snaps with a filter
  • 17. Page 17 Snaps – Manifest • Attaching Snaps to hosts
  • 18. Page 18 Snaps – Taglibs • JSP tag to look up slices & their properties
  • 19. Page 19 Snaps – Host Properties • Looking up resources & properties from the host
  • 20. Page 20 Virgo 3.0 – Demo Snaps
  • 21. Page 21 Regions – Background Bundle ≠ Application ● Need higher level scoping construct than a bundle ● Simpler management applications
  • 22. Page 22 Regions – Scoping in Virgo ● Region scoping - Kernel Space vs User Space ● Application scoping ● PARs and scoped Plans ● Metadata rewriting for bundle/package scoping ● Service registry hooks for service scoping
  • 23. Page 23 Regions & Hook Usability • Control the visibility of bundles, packages, generic capabilities • Bundle Resolver, Find and Event hooks • Service Find and Event hooks • Hard to ensure consistent behaviour across hooks • Need higher level abstraction • Enter..... Region digraph
  • 24. Page 24 Regions – Region Digraph • A directed graph of "regions" • A region is a group of bundles • Regions may be connected by directed arcs • Each directed arc has a filter which controls visibility: • bundles • packages • services • generic capabilities
  • 25. Page 25 Regions – Region Digraph
  • 26. Page 26 Regions – Region Digraph
  • 27. Page 27 Regions – Region Digraph (cont.) • Developed as part of Virgo • Formal model specified in Z • Seen to be useful outside Virgo • Moved to Equinox • Used in Virgo 3.0 • Used in Apache Aries
  • 28. Page 28 Regions & Subsystems • OSGi standard multi-bundle scoping mechanism • Work in progress, public draft soon • Inspired by Virgo regions & scopes, Apache Aries applications, Apache Felix Karaf features, Eclipse features, Deployment Admin deployment packages etc... • Virgo to implement subsystems in a future release
  • 29. Page 29 Regions & Subsystems For more information Go to the talk later today on “Multi-bundle Scoping in OSGi” For even more see Subsystems RFC 152
  • 30. Page 30 Virgo Future • Web Admin Console (Demo at the BoF later) • Nano Virgo based around P2 • Subsystems • Snaps, Nesting & Listener Support • Cloud Come to the BoF, tonight at 18:30 ...
  • 31. Page 31 Virgo Future -Tooling Libra: • Tooling for Enterprise OSGi • Spec compatible only Virgo IDE: • Tooling for Virgo • Not spec compatible (there is no spec) • Very much specialized
  • 32. Page 32 Virgo Future - Tooling Move spec-compatible parts to Libra • Launcher, server visualization, Bundlor, … Let Virgo consume and enhance Libra • With Virgo-specific parts, like PAR projects, EBR integration, … Enhance modularization • Separate build tools (Bundlor, bndtools, PDE) from server integration Remove Spring IDE dependencies Improve performance/footprint
  • 33. Page 33 Questions Martin Lippert mlippert@vmware.com @martinlippert QuestionsQuestions Christopher Frost frostc@vmware.com @cgfrost
