This document provides an overview of Eclipse Libra, a set of tools for OSGi enterprise application development in Eclipse. It describes Libra's scope, the tools included in the initial Juno release such as bundle projects, framework adapters, and the bundle overview. It also briefly demonstrates the bundle dependency view and server console.

3. Five Levels of OSGi (Alex Blewit)
Can’t possibly work Cannot see my class why this uses constraint How do I load a JDBC driver? Bundle Enlightenment
OSGi is written by IBM? ClassNotFoundException? It fails How can I map JNDI Declarative services
I don’t use Eclipse is there Can’t we start the services references to data sources? Remote Services
These classes are the same in order My custom Log4J logger
OSGi is too complex Dynamically update code on
but aren’t? Works on Equinox but not does not work? servers
javax.swing is not there Felix Write a Manifest manually? Tweets about OSGi
Denial
Acceptance
Anger
Bargaining
Depression
hibernate is not working? Let there be a Stack Is there a bundle for Apache

4. JavaEE: If the shoe does not fit
 Tightly coupled
 hardwired
 Not Dynamic
 Restarts with every deploy
 Isolation
 No sharing
 Common libraries etc. xflickrx, Flickr Creative Commons
 Version conflicts
 Hierarchical class-loading

8. OSGi Tools • Too many/Not enough tools
• Different Philosophies
• OSGi Transparent
 Development Tools • Generate Manifests
• OSGi Frameworks are tricky
 Eclipse Libra
• Launching
 Eclipse PDE • Installing
 Eclipse WTP • Etc.
 Eclipse Virgo Tools
 BndTools
 IBM Rational Development Tools
for OSGi Applications
 Silent, still alive???
 Builds
 Maven Tycho
 PDE Builds
