3. Who am I?
• Java/JavaEE, OSGi, GWT, Flex, Android, iOS, Node.js...
simply Code Geek!
• GDG/GTUG Istanbul Lead
• Eclipse Committer
• Conference Speaker

4. OSGi vs Developers
Human rounded ears OSGi?!?
pointed ears nature?
Fully supported by USS Enterprise Looking for IDE support
Wednesday, October 3, 12

5. OSGi: The good(s)...
•Architecture for developing and deploying modular apps
•Build using OSGi APIs
•Deploy to an OSGi Container
Wednesday, October 3, 12

6. OSGi Containers?
•Runtime for the OSGi Apps
•from Symbian to Enterprise
•equinox, felix, knoplerfish...
Wednesday, October 3, 12

7. JavaEE: If the shoe does not fit
•Tightly coupled -- hardwired
•Not Dynamic -- restarts with
every deploy
•Isolation -- no sharing,
common libraries, version
conflicts, hierarchical class
loading

8. Enterprise OSGi
•OSGi programming model: proven, standarts-based,
dynamic, modular, manageable, ubiquitous, evolvable
•Enterprise Infrastructure: persistence, transactions,
distributed, management, naming

10. OSGi Tools: the bad..
•Ant tools: bnd, bundlor •Too many/Not enough
tools
•Eclipse tools: bnd,
bndtools, bundlor, pax, •Different philosophies
sigil, concierge (OSGi Transperent,
Generate Manifests)
•Rational
•OSGi Frameworks are
•Spring tools tricky (launching,
installing...)
Wednesday, October 3, 12

11. OSGi: the ugly...
•development complexity, no more plain java (bundles,
activators, manifests)
•each tool adds its own behaivour and complexity
•different containers, different packaging and
configuration

12. Five Levels of OSGi (Alex Blewit)
can’t possibly work
DENIAL
written by IBM, right?
eclipse use OSGi, I don’t use Eclipse
OSGi is too complex
if you can start up the services in this order
ANGER why does this work in equinox but not felix
please let there be a StackOverflow answer
why can’t this bundles see this class
BARGAINING
why am I getting ClassNotFound Ex
these two same classes are not the same
why doesn’t hibernate work
how do I load a JDBC driver
DEPRESSION why doen’t my custom Log4J logger work
why do I have to write a Manifest manually
sudden dawn of understanding of bundles
see how services can be connected with DS
ACCEPTANCE remote services to other Systems
dynamically upgrade running code
evangelise & tweet & give keynote on OSGi
