Open Source IssuesOpen Source Issues

• Android will open source 2008/Q4– Open source doesn’t mean free of charge

• Sun provides phoneME as JavaME open source– Product shipment without Java logo – must open source– Product shipment with Java logo – need commercial license

AgendaAgenda

ConclusionConclusion

• Linux becomes more and more important, lots of devices shipped with Linux, e.g. PND, MID, mobile phones. Nokia and Google are involved.

• To overcome platform diversity and simplify deployment, embedded Java is the key solution.

• To adopt Java technology into your product, application determines Java configuration.– Customer driven– Operator driven

• Java is complicated in technology and biz model, it’s not good to self-develop but to find Java partner.
