Wireless Network Distributed Application And Research Based On JAVA Platform

With the construction of the 3G network of high-speed data transfer, cellphone network application technology will become the key technology about mobile telecommunication application platform in the future. Now the J2ME platform hard environment becomes more and more general. And now the J2ME market is more and more living. So the J2ME must be an industry standard.J2ME is a branch of Java 2 platform. It use in the application development of the consumed and embedded connected limited devices, especially being fit of more complex and intelligent client. In the wireless application field developers can implement embedded environment computing with adopting the distributed architecture solution. And the Java visual machine in the J2ME platform overcomes dissimilarity of the different machine platforms and operating systems. It makes the embedded developing easier and easier.This paper is started with introducing the J2ME architecture of wireless technology in the Java platform, in the wireless network distributed application research and has put forward a new model based J2ME and servlet for information organization and retrieve, implement a system-WTSE(Wireless translation search engine), in general WTSE system implement the J2ME wireless network distributed application feature. It is used in special search engine, and on that basis refers to current network information organization mode and some new information processing. For gathering , processing and presenting the translation information resource, it has possible ways of optimization and improvement, and also makes attempt about a new mode of wireless translation application.In system implement, it is analyzed three basic function modules: corpus retrieval module, retrieval proxy module and wireless client search module.The main function of the corpus retrieval module is organizing the bilingual information again in the corpus database for the translation. It mainly includes indexing the gathered bilingual materials for quick searching the information users need.The main function of the retrieval proxy module is in response to the services that the wireless clients request, and transferring it to the corresponding retrieval module to request, then processing gotten retrieval information to return to the wireless client.The main function of the wireless client search module is in response to the services that user request for translations. It connects the network by J2ME Connected Limited Devices and communicates with the retrieval proxy module, finally displays the result on the wireless client.This paper based on the research of wireless network technology in the Java platform, through the elementary realization of wireless translation search engine, opened up broad possibilities for the combine application of Java wireless and full text retrieval technology.
