& Wireless Application Development
- J2ME -
Wireless application development
has the following characteristics:
multi-device support, since no single device can serve entire organization's
multi-RF network support
and database support
integration with web
application server platforms
While several different device
platforms are being promoted by major device vendors, such as PalmOS, Microsoft
Windows CE, PocketPC and Sambian's EPOC, Motorola and Lutris Technologies (a
Santa Cruz, California company) have teamed up to offer Java-based
development platform for iDEN handsets. They duo have decided to bundle
Lutris' open-source Enhydra application server with Motorola's SDK for iDEN.
With this set of Enhydra and J2ME (Java 2 Micro Edition), programmers can
develop both server-side and client-side software that takes advantage of
Sun's J2ME specifications. iDEN handset that transmits both voice and data,
will be available in mid 2001.
Enthusiasts for J2ME point out
that J2ME is more open than WAP, because you may choose not to utilize a
micro-browser for J2ME applications.

Directory and Vendor
We said in December 2000 that it was still too early to determine larger potential of widespread
adoption of J2ME for wireless applications beyond Motorola's iDEN
network applications. We also said that in the long run, we expect J2ME to get wider network
and device support. Now in early, 2002, J2ME has succeeded in
garnering excellent support across all groups - hardware developers, phone
manufacturers and enterprise developers. However, It is important to
understand the role of J2ME - it is useful primarily for developing packaged applications and device drivers
for smart phones and PDAs by those application developers who are targeting
these applications for carriers. For enterprise vertical applications,
business application developers should continue to utilize higher-level tools
like those available from IBM, Sun (J2EE), BEA, Oracle, Sybase iAnywhere, Microsoft, @Hand,
etc.. The latter category of tools will continue to have superior backend
integration. They can develop client application pieces in J2ME and then
integrate these with backend applications.
