For more, go to news item. It has ported Blackberry applications to work on J2ME. We also said that in the long run, we expect J2ME to get wider network and device support.
Freeware for Java
Now in early, , 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. 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.

WAP standardizes access not only for mobile phones but also for PDAs personal digital assistants and pagers. WAP-based sites typically present information in one or two lines of data: company name and phone number; flight numbers and times; currency and exchange rate, etc. This is the information that WAP is good at handling, and it is quick and easy for individuals to access. But WAP is not for everyone.
Due to its bare-bones nature, WAP benefits the most individuals with a high demand for mobility. Tim: On those same lines, the Java 2 Platform, Micro Edition J2ME was developed specifically to address the vast consumer space of small devices, ranging from smart cards to pagers.
This space, with its limited memory and display constraints, has proved to be an ideal environment for Java. But before we venture too far into what J2ME is and the benefits it provides, it might make sense to state up front what it is not, and that is a replacement for WAP.
Those who follow this space will quickly agree that, instead of looking at it as a WAP competitor, J2ME should be looked at as a complementary technology used to further expand the usefulness of wireless access and applications. Unfortunately, although useful in what it does, it does have a few shortcomings, including security and the fact that it requires constant airtime for stand-alone or offline operations. When coupled with J2ME, however, users will now be provided with a full-featured Java-based application environment from which to enhance their experience.

What makes it especially appealing is the fact that implementation is as easy as having your users download the application via their standard WAP browser. Furthermore, by employing this type of technology, users will no longer be restricted to the limited monochromatic interfaces seen on WAP devices today, but rather we will enjoy full-color, animated graphics and applications that are much easier to navigate.

Once a Java application has been stored on a handset, it can then exchange data with backend information systems using the existing WAP infrastructure. Ana: Companies in the mobile data business and end users will all benefit from WAP. The devices will cover a wide base of end-user needs, and phone manufactures will continue to improve and develop newer and more sophisticated devices that will continue to support and enhance services and the user's experience.
Because WAP is supported by all major phone manufacturers, it is very likely to become very successful.

Java is also an established platform, and J2ME will appeal to developers, which may lead to better wireless applications. Some individuals may not take J2ME seriously right away, however, because Java has traditionally been better suited to a desktop- and server-based environment and therefore appeals to mainstream developers more than it does to embedded-system builders.
Tim: I could not agree with you more, Ana, except for the statement that J2ME is not being taken seriously. In fact, if you consider the upcoming 3G third-generation standard, most vendors are already considering the use and inclusion of the technology. Moreover, once more individuals realize the huge potential that Java can bring not only to their tethered applications but also to those that are wireless, I expect to see an even bigger adoption of the technology.
The only real problem I see with WAP, or more specifically WML Wireless Markup Language , in the future is that, just like any specialized language or technology, few qualified individuals are or will be available. Here is where Java really stands proud: as long as individuals continue using it -- and I suspect that they will for some time to come -- a constant source of talent will be available.
Ana: WAP has been designed to leverage the established Internet infrastructure by taking advantage of investments already made in programming, applications, development tools, and Web servers. WAP is also closely aligned with existing data networking standards and Internet technologies, including IP and XML, while focusing on the unique requirements of wireless access.

From a hardware standpoint, device manufacturers ranging from Nokia to Motorola are all building J2ME into their next-generation wireless handsets. Ana: 3G is the generic term used for the next generation of mobile communications systems. As 3G becomes more widely available in the United States, home banking, ecommerce, and online trading applications will be modified for the mobile environment and videoconferencing. The wireless terminal will be the personal gateway to the world of voice, data, video, mobile Internet, and interactive multimedia communications.
Tim: I agree that once 3G has reached a saturation point more users will find the wireless experience appealing.

From a J2ME standpoint, adoption is already taking place, as J2ME has been chosen as the industry standard for wireless devices by the Third Generation Partnership Project, a group responsible for defining the specification for the next-generation handset application environment.
WTLS was specifically designed to conduct secure transactions over a low-bandwidth environment without requiring PC-level processing power or memory in the handset. The problem occurs when the data is handed over from WTLS to SSL, a process in which the data is decrypted and then re-encrypted, meaning that for a split second the data is not secure.
