Extending, Expanding, and Porting Mobile & Embedded Community Projects

by Phil Bartholowww.bartholo.com/OSCON/

‣ Learn how the core M&E Community projects have been the catalyst for numerous ports, extensions, and expanded open source uses not previously envisioned when the community launched.

Goals

Java Momentum

6 Billion Java-Enabled Devices

2.5 Billion Java-Enabled Phones

3.5 Billion Java Card

20 Million Java Set-top Boxes

800 Million Java Desktops

180 Operators DeployingJava Content

6 Million Developers

Why Open Source?

•Bring communities together and extend them

•Engage platform and application developers, ISV's, tools vendors, and operators

•Industry-wide collaboration on platform, tools, and applications

•Remove inefficiencies and barriers to innovation

•Drive common implementation and consistency

‣ Introduction to the Mobile & Embedded Community

‣ Mobile‣ Media‣ Embedded

Agenda

Community Structure

‣ The only place in the industry that brings together

• Complete source code of Java ME implementations

• Platform experts and spec leads

• Testing tools

• Experienced application and content developers

• Lots of cutting-edge samples and source code under BSD

• 3rd party technology, collaboration, and code

• Active community, very friendly and helpful

‣ The best place to jump-start your involvement with Java ME

Why Get Involved?
