Because XML is a W3C standard and has characteristics like platform independent, it has a critical role in electronic commerce. Many electronic commerce systems are already using XML. Business rules and procedures should be standardized for efficient B2B electronic commerce. But a lot of companies have its own XML documents instead of standard documents. In this paper an XML message processor is designed. Clients may request services in XML and server returns response in XML in this system. This XML message processor can be applied easily and used efficiently in electronic commerce systems.

본 논문에서는 웹, 모바일 환경에 적응 가능하고, 다양한 서비스의 지원이 가능한 글로벌 Peer-to-Peer(P2P) 엔진에서 서비스 모듈, 네트워크 모듈, 레파지토리 모듈간에 발생되는 메시지를 처리하는 메시지 디스패쳐의 설계 경험을 기술한다. P2P엔진이 이 기종 네트워크환경에 적응 가능하고, 다양한 서비스들을 동시에 지원하기 위해서는 피어 간 또는 엔진 내부에서 발생하는 많은 메시지들을 원활히 처리하는 모듈이 필요하다. 이를 위하여 메시지 처리를 위한 글로벌 P2P 엔진의 메시지 디스패쳐를 제안한다. 메시지 디스패쳐는 글로벌 P2P엔진에서 지원하는 서비스 또는 다른 모듈에서 발생하는 메시지들을 우선순위와 마감시간을 이용하여 작업순서를 배열하는 Message Queue, Message Queue에 적재된 메시지들을 분석하여 처리하는 Message Processor, 메시지 디스패쳐와 서비스 또는 각 모듈간의 메시지의 전달을 위한 공유 버퍼인 Service Buffer로 구성되어져 있다. P2P 엔진에서 메시지 디스패쳐를 이용하게 되면 다양만 서비스에 적응가능하고, 모듈간의 투명성을 제공하고, 신속한 메시지의 처리가 가능하게 된다.

This paper proposes the wireless integrated service for controlling networked appliances. Using wireless devices such as celluar phone and PDA which can communicate through Bluetooth and CDMA technology, home appliances are accessed and controlled from outside of house. The XML and the SMS message format is designed to specify controlling information for home appliances. Also the mobile agent and the message processor for networked appliances are implemented in the home gateway. In order to verify the proposed service system, a universal remote controller for cellular phone and PDA and network appliance simulator on web browser are implemented. Correct operation is verified through simulation using them.

Web services are key applications in business­to-business, business-to-customer, and enterprise applications integration solutions. As the mobile internet becomes one of the main methods for information delivery, mobile Web Services are regarded as a critical aspect of e-business architecture. In this paper, we proposed a mobile Web Services middleware that converts conventional internet services into mobile Web services. We implemented a WSDL (Web Service Description Language) builder that converts HTML/XML into WSDL and a SAOP (Simple Object Access Protocol) message processor that performs SOAP message handling, chain and handling of server requests. The former minimizes the overhead cost of rebuilding mobile Web Services and enables seamless services between wired and wireless internet services. The latter enhances SOAP processing performance by eliminating the Servlet container (Tomcat), a required component of typical Web services implementation. Our main contributions are to overcome the latency problem of current Web Services and to provide an easy mobile Web service implementation. Our system can completely support standard Web Services protocol, minimizing communication overhead, message processing time, and server overload. Finally we compare our empirical results with those of typical Web Services.

This paper presents is for the design and implementation of EDI document exchange system based on XML To create a customized document of the users' choice, it designed and created the transaction processor and the template manager, and to make it accessable with the original EDI, a converter function is included, Also, on this system, this protocol stores EDI message structure that needed to exchange as XML format and controls it as DOM API for user can use previous system, And provides interface for user can create template files with converter and transfer necessary elements that can be chosen by user. For this purpose, This system proposes a shows structure information and document converting mechanism solution of EDI documents based on by using XML which does not show proper document conversion mechanism solution in other system so far.

Advances in communications and control technology, the strengthening of the Internet, and the growing recognition of the urgency to reduce the risk and production cost are motivating the development of improvements in the traditional manufacturing industry. In this paper, we developed a remote dust collector bag control system which is a combination of advanced IT and traditional dust collector based on the event. At first, we made the A/D(Analog/Digital) converter using a micro processor because the differential pressure transmission, which is a sensor of the dust collector, produces analog volt data. A/D converter can provide RS-232 communication to connect with Power Line Communication(PLC) modem. And, n-bytes message format was defined for the efficient dust collector bag information transmission from a dust collector to a user. Also, we designed the data types to model the dust collector and the dust collector bag, and they were logically modeled using XML and object-oriented modeling method. In addition to that, we implemented the system for showing the dust collector bag exchange time exactly to users at real-time using various visual user interfaces.
