e4 – dependency injection

  Riena has Dependency Injection for OSGi Services and Equinox Extensions for more than a year

  Implemented before e4 or JSR 330 was finished

  e4 now implements the JSR 330 standard and uses dependency injection in many places

  e4 not only injects OSGi Services but Application Services and other objects (i.e. parent Composite)

  both implementation (NOT surprisingly ) use annotations

Riena - XWT

  Riena separates View and Controller

  View contains the definition of Widgets, Colors, Fonts, Layout

  Controller contains data binding, event listener, view logic

  The BindingId links the widgets in the view with the Ridget that the Controller accesses.

  Action: Remove the Java View and replace it with a XWT View.

Conclusion

  e4 has many components that are interesting for Riena

  some are more stable than others

  The Riena implementation gets a lot easier on e4 than on 3.x

  We will soon make a Riena build available for everyone to try out.
