OSGi has a name of being hard to use and complex. With today’s tools and frameworks this is far from true! In this presentation you will see an OSGi application being built from scratch and learn about package imports and exports, dynamic services, dependency injection and integration with JAX-RS and MongoDB. This talk is both for developers new to OSGi that want to learn the OSGi basics, and for developers with some OSGi experience looking to optimize their workflow.

Modularity ?!

3. Observations
!
Extremely agile
(first mover advantage)
!
Architecture (and code base)
should be able to cope with change
Trend
!
Applications tend to
grow bigger and more
complex
!
Agile development
and refactoring have
become more common

4. Modularity
is the answer

5. What we lear ned about OO design in university :
Prevent
(tight)
coupling
Promote
cohesion

6. Modules Service Lookups

7. What do we need
design
consequences
High-level
enterprise APIs
Architectural
focus on
modularity
Runtime
dynamic
module
framework
Right now,
OSGi is the
only option
let’s not
reinvent the
wheel
for modularity?

8. Stop talking…
and show me code!
