Sun has completed the Mobile Information Device Profile (MIDP 2.0) standard and made available the final MIDP 2.0 specification, reference implementation, compatibility test suite and beta version of the JavaTM 2 Platform, Micro Edition (J2METM) Wireless Toolkit 2.0. Developed by more than 50 wireless industry leaders worldwide to extend the base collection of JavaTM technologies for mobile devices, MIDP 2.0 supports new and enhanced gaming, graphics, video, audio, security and many other features for mobile devices, such as cell phones and personal digital assistants.

MIDP is a set of Java-technology APIs that, together with the Connected Limited Device Configuration (CLDC), provides a complete J2ME application runtime environment to support the majority of low-cost mobile information devices in use today, including mobile phones, digital assistants and two-way pagers. It provides Java technology developers the opportunity to leverage their skills onto a wide variety of mobile devices, taking into account the individual capabilities and limitations of each.

With the availability of MIDP 2.0, manufacturers and service providers will be able to quickly and cost-effectively deliver increased functionality, more robust applications and a better user experience to mobile devices using the J2ME platform. Providing the foundation for highly graphical and intuitive mobile applications, MIDP 2.0 now brings the following new features:

• Enhanced user interface: MIDP 2.0 makes applications more interactive and easier to use. It also provides greater extensibility and a more flexible layout for increased application portability across a wide range of devices with differing screen sizes.

• Media support: MIDP 2.0 allows developers to leverage the full audio capabilities of each device.

• Game support: MIDP 2.0 adds a Game API that provides a standard foundation for building rich games.

• Expanded connectivity: MIDP 2.0 adds support for leading connectivity standards beyond HTTP, such as HTTPS, datagram, sockets, server sockets and serial port communication, providing applications several ways to exchange data with back-end services.

• Push architecture: MIDP 2.0 includes a server push model whereby MIDlets can be registered to be activated when a device receives information from a server, such as news updates, stock trading, online auctions and real-time messaging.

• Over-The-Air (OTA) Provisioning: To ensure a standard approach to MIDP application deployment that works across a range of mobile devices, OTA provisioning is now required as part of the MIDP specification.

• End-to-end security: MIDP 2.0 adds a robust end-to-end security model, built on open standards, that protects the network, applications and mobile device.

Sample applications leveraging the new features introduced in MIDP 2.0 could be a karaoke game streaming audio files over a wireless network, multi-player arcade games, a supply-chain management (SCM) tool accessing corporate data over a secure wireless connection, traffic alerts launching a related street navigation application and more.
