5. what (the hell) is this talk about?!?
luckily no horoscopes!
OSGi for the earthlings: Meet Eclipse Libra
EclipseCon 2010/2011, JavaOne 2011/2012
Eclipse Gemini
Eclipse Virgo
Wednesday, October 9, 13

6. so what (the hell) is OSGi?!?
architecture for developing and deploying modular
apps
build using OSGi apis
deploy to an OSGi container
a dynamic modular runtime for Java developers
Wednesday, October 9, 13

7. containers?
from Symbian to Enterprise
equinox
felix
knoplerfish
µJonas
...
Wednesday, October 9, 13

8. tools
Ant tools: bnd, Bundlor
Eclipse plugins: bnd, Bndtools, Bundlor, Pax, Sigil,
Concierge
Rational
Spring Tools (Eclipse Virgo)
back to 2009
later...
Wednesday, October 9, 13

9. problems!!
development complexity, no more plain java (bundles,
activators, manifests...)
different tools, adds its own behavior and complexity
(ant, maven, packaging..)
different containers, different packaging and
configuration
Wednesday, October 9, 13

10. the (OSGi) Developer
need the learn the OSGi
way, well it is a new
platform...
need to learn each tool
need to know each
container
pointed ears
science officer
half human - half vulcan
trying to understand
human nature
rounded ears
developer
java & OSGi
trying to understand OSGi
Wednesday, October 9, 13

11. there used to be a similar problem!!
Building Java Web/J2EE apps!
Different vendors
Different servers
Different configurations
Different tools
Did old Java Web/J2EE apps were really portable?
Wednesday, October 9, 13

12. So what happened?!?
Eclipse Web Tools Platform
abstraction of runtime from the project
adapters for the runtimes to integrate the IDE
target platforms for the runtimes
Wednesday, October 9, 13

13. So what happened?!?
Eclipse Web Tools Platform
abstraction of runtime from the project
adapters for the runtimes to integrate the IDE
target platforms for the runtimes
really need to reinvent
the wheel?

14. road to Libra... OSamI
sorry, not a japanese beer
targets social needs: energy efficiency, remote health,
smart home, mobility..
based on OSGi
first results: Green building (grenoble, thales, bull),
Smart Home (VTT), Mobile (Siemens), Embedded
(ProSyst)
Wednesday, October 9, 13

15. OSamI Tools
OSamI tools for OSGi developers
abstraction layer between bundles and containers
built on server adapters (well OSGi runtime adapters)
demo at EclipseCon 2010
moving to Eclipse repo... (2011)
Wednesday, October 9, 13

16. PDE to OSamI

Not only Eclipse plugins (PDE)
Support for multi OSGi frameworks

17. Eclipse Libra
tools for creation of deployable artifacts for application
servers implementing the OSGi Enterprise specification,
(Web Application Bundles)

OSGi Enterprise deployable artifacts (Dynamic Web
projects to a Web Application Bundle projects)
Wednesday, October 9, 13

18. Eclipse Libra (cont.)
tools for editing and validation of the metadata of OSGi
Enterprise artifacts, (extension of the PDE Manifest
Editor for editing manifest headers)

of configuring an OSGi-based application server,
starting it and deploying OSGi enterprise artifacts.
Wednesday, October 9, 13

19. Libra in a Nutshell
adapters for OSGi containers
no runtime info in bundles
dynamic packaging, deploy, run, debug
easy to develop new adapters
war products (packaging OSGi container with bundles
as a war file)
gemini profile (OSGi web profile)
