Netbinox is the fastest OSGi container that provides a 40% faster startup speed for desktop applications. It achieves this speed by avoiding I/O through caching of class and resource loading. The presentation provides the history of Netbinox, including experiments with OSGi at Sun and Glassfish, and how Netbinox was developed at Oracle to align NetBeans IDE with JDeveloper. It demonstrates Netbinox's faster startup and discusses the technical differences from Equinox, such as using caches for class and resource loading. Netbinox is now used in NetBeans IDE 7.1 and future alignment of NetBeans with JDeveloper is discussed.

Agenda
• Being Fast!?
• A bit of history
• Demo
• Technical details
• Q/A

3. http://netbinox.apidesign.org
Slow I/O During Startup
Demo

4. http://netbinox.apidesign.org
History 1 - Experiments
• Sun and OSGi
> Glassfish adopted OSGi in 2008
• Netigso
> Friday project
> Felix based
> Parallel mode
> Reuse of bundles
• Glassfish in Nb
> Middle of 2009
• Problem: How to get this into release?

History 2 - Acquisition
18 months of despair
• Sun collapsed in Spring 2009
> Acquired by Oracle
> Approved in January 2010
> Czech Republic LEC on Sep 1, 2010
• JDeveloper
> Primary IDE for Oracle Enterprise Technologies
• Eclipse Foundation
> Member and Contributor
• Problem: Can NetBeans be useful for Oracle?

6. http://netbinox.apidesign.org
History 3 - NetBeans 6.9 Theme
• NetBeans Platform based on standards
> Standard UI - Swing
> Adopt OSGi as de-facto standard
• OSGi interoperability
> Reuse existing bundles
> Use bundles on server/client side
> Use NetBeans APIs in OSGi mode
• Problem:
> Is that enough to align with JDev?
The public plan

JDeveloper
Going the same direction
• JDev converted to OSGi meanwhile
> Most of the work done
> Big Bang rewrite
> Using Equinox
• Long term synergy vs. short term benefits
> Reuse pieces of NetBeans in future
> More speed right now
• Netbinox on the rise
> “Just” reuse NetBeans “startup caches”

Being Fast with Caches
Demo

Caches & Speed
Avoid I/O
• 40% faster
• Useful for desktop applications
> Start speed is important
> “Morning” launch
• Intercept I/O queries
> loadClass, getResource
> File.exists()
• Modular vs. monolithic apps
> Deployment modular
> Start is monolithic

The Differences
What is different in Netbinox?
• 100% compatibility for bundles
• Class and resource loading
> ZipBundleFile replaced by JarBundleFile
> Thread Context Class Loader
• Equinox hooks
> Registered slightly differently
• OSGi APIs in Separate JARs
> Shared by Felix & Equinox
• Own Launcher
> Configuration files use NetBeans format

11. http://netbinox.apidesign.org
The Presence
• NetBeans IDE 7.1 uses Netbinox
> Mylyn + Bugzilla Connectors
> Orbit bundles (JSCh, Apache)
• JDeveloper on Netbinox
> Other features than a speed
• The common ground
> OSGi as lingua franca
> How do we share?
With future outlook
