It can be said that Java technology is born from the beginning of the Internet, and it can be seen that it can be seen in less than ten years of development. Its development is closely related to demand and guided demand. In 2003, Java has fully promoted its technical strategy and market strategy in the two major directions of Web services and mobile communications.

Motorola is expected to be expected to put on the Asia-Pacific market this year. ◆ In February 2003, the third-year long-distance telecom operator of the United States announced its PCS video service wireless application business that adapts to multimedia needs. The service is 1KTV, based on Java technology, supports mobile download J2ME applications, providing custom news, financial news, weather forecast, sports news and entertainment content for Sprint's PCS wireless users. The service charges are $ 3.95 per month. ◆ In February 2003, the leading Java Solutions Supplier in the mobile field announced that its Optimized version of its JBED ME will fully support the new PXA800F mobile phone processor for Intel companies. Esmertec As a leading provider of embedded Java Virtual Machine in the mobile field, Esmertec is a leading provider of embedded Java Virtual Machines, its wireless and enterprise-level solutions are completely based on Sun's J2ME technology and JBED microcanic platforms. The JBED platform can supply service on small devices. Business, mobile device suppliers, application developers and enterprise IT organizations provide high performance computational enrich user experience. It is alleged that JBED ME is the first JVM solution selected by Intel's PXA800F. JBED MEs are licensed by Sun Authorization, providing high-performance calculations on small terminal devices for service operators, application developers, and mobile device manufacturers. ◆ In February 2003, the wireless communication semiconductor solution manufacturer Nanoamp Solutions revealed that its new product MOCA-J (Memory Oriented Coprocessor Accelerator Technology for the Java Platform) will provide a richest performance for your mobile phone, especially to execute J2ME software. The speed is 20 times. ◆ In February 2003, the leading enterprise M7 in the field of enterprise application integration technology began to work with the Star Partner cooperation plan of the BEA. M7 Application Integration Platform provides a solution to the BEA user to manage J2EE development complexity.

The most active two aspects of Java technologies can be seen above. Java technology is currently the most active fields roughly divided into two large-oriented - business applications, aims to enhance the company's competitive J2EE; facing wireless applications Provides more, more convenient personalized J2ME and Java mobile apps. Among them, J2EE is in the United J2EE, and is divided into the following points: ◆ Big companies headed by Sun, BEA, IBM, continue to cooperate and compete in server products and technology; ◆ Continue to appear in IBM, HP, Many of the companies headed by Oracle, in terms of products related to server products and technologies and integration tools, etc.; Will go out and enter, while other software development tools and products related to Web services will be more abundant.
Mobile computing and embedded development trends
Some phenomena in mobile computing and embedded systems indicate: ◆ 2003 Java mobile phone will launch and drive new round of competition boom in domestic production and consumption; ◆ Beginning in 2003, in the next 2 ~ 5 years The huge business opportunities and fierce competition of mobile communication operators and mobile device applications that are not limited to mobile phones are likely to be interact with other development of e-government, e-commerce; ◆ Intel will be involved in smartphone chip fields will be given mobile phones. The price, performance, development process, etc. have brought a huge impact; ◆ Mobile devices represented by Java mobile phones have taken to the Linux operating system and Java technology, and it is estimated that after a period of practice, it will be the strategy of Microsoft. Form a continuous influence with product ideas.
to sum up
Since Java and Java-related technologies have a certain basis, the future development of Java technology will be higher than the performance of hardware products, more popular, and more demand A tendency that has gradually fused extensive. For example, e-government, e-commerce, etc. For the manufacturer of website operators and commodities, there is a certain size or even large-scale government departments and merchants, but for information and goods consumers, more distribution In the world, there are different consumer people. This seemingly unsuitable various information needs will eventually collect together in some way, and the information products and hardware products that adapt to different needs will be all flowered, and they are unprecedented, and they will be in the same way. In China, after the previous year's e-commerce boom and 2002 e-government promotion activities, the Internet has different degrees of demand from government officials to ordinary people. After the Web service research and application have achieved a certain basis, how to better share various resources in the web service architecture, easy to interactive communication, and more efficiently conduct collaborative works to become the problem of application developers and users. At the same time, using the standard technology of Java platform, XML and other standards to build a strong functional, safe and reliable e-commerce and e-government system, and related research and implementation of the Digital Olympics will also fall into practice in the next few years.
