Previous process for issuing and messaging tax-invoice needs too much cost and has risky problems such as loss or forgery. A rule for an electronic tax-invoice can make up for the weak points. In the tax-invoice system based on web environment, the messaging electronic tax-invoices is more important than the issuing it. Therefore, a messaging system should be developed for submitting tax-invoice efficiently and safely. In this paper, we implement an electronic tax-invoice messaging system based on Hermes 2 which is an open source framework for electronic document messaging.

This paper is a proposal of the world-wide messaging system for supporting wireless internet messaging against the existing system which has many limits on functionality and structure. To this work, this paper proposes the hierarchical structure to ensure an extensibility of an existing messaging system, and show the possibility via implementing and operating together wireless units.

B2B(business-to-business) commerce has become the prime driver of contemporary electronic commerce. Under B2B commerce, corporations often must operate across organizational boundaries to share their business processes. Workflow management was proposed by Aalst(4, 5) to support several business partners that are involved in shared workflow processes in B2B commerce. We designed a messaging system for B2B workflow, where heterogeneous workflow management systems on each organization for trade were integrated. Based on Aalst's example in(4, 5), we analyzed B2B workflow by using class diagram, use case diagram, activity diagram, and statechart diagram of UML, and designed the messaging system, We also demonstrated a prototype system which was implemented by using Java API and XML. To compare with a holistic system such as EDI systems, the messaging system allows the business partners in B2B commerce to communicate with each other by dedicated messages and integrate each B2B interoperable workflow without any restrictions.

Because XML is a W3C standard and has characteristics like platform-independent, it has a critical role in e-commerce. Business rules and procedures should be standardized for efficient B2B integration. But a lot of companies has its own XML documents instead of standard documents. Therefore many organizations try to make standards for e-commerce based on framework. In this paper, n messaging system is designed and implemented. Client request service in a XML and server return response in XML in this system. So we can more easily and efficiently build e-Procurement system based on this XML messaging system.

As Internet is spreaded widely, the virtual communities among people with the same interest and hobby are dynamically created. The exchange of fruitful opinion and information makes them to be closed, not only with the help of the messaging system but also wireless terminals. The messaging system is a core technology supporting the global community services like chatting, messenger, short message services, and file sharing services. The paper focus on the design of software architecture for messaging system and the engineering model for QoS support.

In ubiquitous environments, context is any information that can be used to characterize the situation of an entity such as a person or an object. Many sensors and small computers collect contexts and provide applications with them. Thus, ubiquitous applications need to represent contexts and exploit them effectively. In this paper, we design and implement a context-aware messaging system, called UMS (Ubiquitous Messaging System), based on Java and Jini. UMS can represent various contexts using XML scripts, and communicate text messages regardless of user's location using the proxy mechanism of Jini.

Costs and times, resources was better decreased than former times because it had been introduced EDI(Electronic Data Interchange) system. Nevertheless, many problems has been raised as before, that is high costs and data re-using, the rapidly changing environment, etc. To solve these problems, it was attempted to introduce XML technology at traditional EDI System. From this point to view, 1 designed and implemented XML/EDI System based on Internet(Internet Messaging System) in this paper. And I selected some services as basic service among many services which is provided at XML/EDI System, that is message sending and message receiving, message retrieval. Other service of client system was composed of MapIn and MapOut module. MapIn Module is to parse the received XML Message and to store XML Data to RDB system. And MapOut module is to generate XML Message after extracting data from RDB system and to transfer XML Message to recipient. Hereby, XML/EDI System(XEDI System) provide document re-using, the various result(output) generation f3r various requirement and directly interface with DB. Therefore, This System(XEDI System) is more various and more flexible than the existing Messaging System that just provide transfer and retrieval service

The BioPlace system is a web-based collaborative system which offers effective exchange of information and research activities among the genomic researchers. BioPlace supports collaborative works among the related group members through Personal Workspces and Team Workspces which are virtual spaces on the web. Jabber is an open messaging system based on XML, giving an efficient way of developing messaging services by providing various functionality for real-time communication and interoperability with other foreign messaging systems. In this paper, we have designed additional Jabber XML protocol to extend Jabber messaging system to be used as real-time communication methods on the BioPlace collaborative system. Also, according to the protocol, we have developed both the extended Jabber server and the BioPlace messenger client.

A policy of instant messaging usage is offered in this article. First, a brief introduction of instant messaging system structure is described. The main threats and vulnerabilities of Instant messenger (IM) are described in the second part of the paper. Instant messaging applications offer so many advantages in so many different fields that they're fast becoming the preferred communication tool for a number of different professional scenarios. When properly implemented, instant messaging can be a true asset to the business by making communications easier throughout the organization. If instant messaging is carelessly implemented, though, it can cause problems with privacy and may expose the organization to various forms of malware. The solution offered in this paper is one of the effective ways against threats of IM. However, the system cannot be secured entirely. All we can do is reducing the risks.

This paper deals with a web-based public address system for conveying information for different institutions. An architecture for a Short Messaging Service (SMS) based public address (PA) system that can be programmed by an authorized mobile phone or device is proposed. This PA system will facilitate information transfer from heads of offices, managers, directors, and deans of the institutions to its constituents or unit area as well as enable postings of information with proper authentication and validation remotely. The system supports high priority messaging, allowing the conveyance of critical and time sensitive information. The mobility management support for the PA system will be based on the Hierarchical Mobile Internet Protocol version 6 (HMIPv6), hence, allowing for a seamless connectivity to the system. The major advantage of this proposed PA system as compared with the traditional electronic displays and bulletin boards is seamless mobility wherein the display devices can be programmed remotely by heads of the institutions and business organization. It also allows faster communication and immediate actions concerning the different institutions, organizations, and businesses, thus, ensuring high productivity.
