Why Java ME (J2ME)?

Success stories/Case studies elsewhere on the web:


  • Alone among all the current technology, and because of its modular approach to targeting small devices, Java ME (J2ME) has positioned itself as the best solution for an extremely wide range of small devices. With some incremental learning, a single java developer can quickly master coding conventions from smart cards all the way to high powered devices like settop boxes and high end PDAs.

  • The huge and fast growing base of java developers worldwide provides a ready resource for creating Java ME (J2ME) apps.

  • Java ME (J2ME) promises developers and companies portability across the widest range of devices imaginable. Profiles target specific devices, but portability is maintained to some extent across configurations.

  • Java ME (J2ME) on handsets like cell phones is supported by ALL the major carriers (including Verizon Wireless, which had previously been a BREW-only supporter), unlike its competitors like BREW and Microsoft technologies.

  • Java ME (J2ME) on handsets is strongly pushed by ALL the major phone vendors (Nokia, Motorola, Sony-Ericsson, etc), unlike partial competitors like BREW (which is not supported by the major phone vendors because they have their own competing OS called Symbian) or the competing Microsoft technology (which is a fringe player at best).

  • Java ME (J2ME) on cellphones is a PROVEN commercial success. More than 94 million devices have been shipped worldwide since last year (July 2003)

  • More than 13 million consumers download java apps using NTTDoCoMo's 2.5G i-appli service, with 60% of the apps being games (Fall 2002).

  • European mmO2 saw the number of Java games purchased to date on its site increase from 278,000 to more than half a million since its last reported figures at the end of March 2003. (July 2, 2003)

  • In Japan, Java is what's saving NTTDoCoMo's i-mode. Japan's dominant wireless company (which partly owns AT&T Wireless) has acknowledged this fact by reporting ARPU (average revenue per user) for Java users separately from non-Java users. In July 2001, one investment bank analyst estimated that, as of June, Java users were generating 425 packets per day of usage (on average) compared to 180 per day for non-Java users -- a huge differential. J-Phone introduced Java in July, and already the Java handsets are the top sellers.

  • Palm and IBM recently announced in July 2003 that ALL Palm Tungsten devices will ship with an integrated Java ME (J2ME) runtime by Fall 2003.

    This is a major advance for Java ME (J2ME), as the Palm OS represents the strongly dominant handheld OS. More than 97% of all handheld software sold in 2001 was for the Palm OS, and Palm OS is gaining dominance in the enterprise as well , with Palm OS licensees accounting for more than half of all handhelds sold to enterprises worldwide, compared to 32 percent for Pocket PC licensees. In addition, the Palm OS made up around 85% of handheld retail sales in the US in March 2002. Finally, more than 85 percent of enterprises chose Palm OS as their platform for mobile solution development, according to a 2002 report by Maritz Research. And, in a 2002 study by the Gantry Group, Palm Powered handhelds had a 41 percent lower total cost of ownership than those that use the Microsoft Pocket PC platform.

  • Java support is becoming standard in many of the current PDAs, including Sharp's new Zaurus PDA.

  • All-Java PDAs are coming out, including the really good looking Kyocera Pocket Cosmo PDA, and the aJile aJ-100WRP.

JavaCard (Java Smart Card)

  • Java ME (J2ME) on smart cards is the de facto standard for this fast growing industry. It is supported by the largest smart card vendors, including Schlumberger and Gemplus, and is running on more than 100 million smart cards worldwide.

  • American Express and Visa have adopted Java Card technology as the platform of choice for the development of their smart card applications. The very popular AMEX Blue card (current circulation: more than 4 million in the USA) is a java smart card. After only 18 months, Blue accounted for 10 percent of all U.S. Amex cards, and should hit about 10 million cards in 2002. There are also about 7 million VISA smart cards in the country.

  • Target stores began the first large scale smart card based loyalty program in the United States last September 2001. Target sent out 2.5 MILLION java smart cards, along with free smart card readers to its customers. In addition to providing secure access to their store account, consumers can go online on their home computers to download the loyalty programís electronic coupons onto their smart cards. Target will redeem the coupons at the POS in stores. (get Target smart card).

  • Government agencies are currently issuing Java Card technology-based smart cards as their new identification cards to replace existing "paper" identification cards. Most recently the Federal Aviation Administration (FAA) named Java Card technology as the platform of choice for the Transportation Workers(TW) card, the first national identity card for transportation workers. The Department of Defense is issuing a Common Access Card to 4.3 million active duty U.S. military personnel and eligible contractors. The Government of Taiwan will deploy a Java Card technology-based smart card as their new health insurance identification card to all 24 million residents.

  • 112 million javacards were shipped in 2001, which made up 51% of the total number of multi-application smart cards. It is projected that 200 million javacards will be shipped in 2002, making up 56% of the total multi-application smart card market.

  • Telecommunications carriers such as China Mobile, France Telecom, Hong Kong Telecom, Orange, Swisscom, Telecom Italia Mobile and Telefonica have deployed millions of Java Card technology-based Subscriber Identity Modules (SIM)cards worldwide. Java Card technology-enabled SIM cards allow operators to provide secure, innovative services on mobile devices. In 2001, Java SIM cards grew 92% and made up about 25% of all SIM cards (96 million java SIM cards). The number of java SIM cards is expected to grow to 162 million (or 36% of total) in 2002.
