....only addressed security through a user identifier and password scheme. It now includes transport layer encryption over HTTPS connections. Of course, use of the Internet for database access, collaboration, and real time monitoring has many antecedents. We mention four examples. Evans and Rogers [2] report on using Java applets and CORBA to reimplement (parts of) an existing multi user WWW application, replacing the existing CGI scripts. They found the applet CORBA combination to be better at performing client side applications, to be easier to maintain, to be simpler to program (because of ....

....by the CORBA approach allows the distributed applications to be composed of legacy and third party software as well as newly developed software. The CORBA approach as it is today, has some limitations. The CORBA does not solve the problem of deploying the components of a distributed application (Evans and Rogers, 1997). The programs comprising a distributed application must be installed on the hosts where they will execute. This usually represents a problem for the client software in a multi user distributed application. The deployment problems are faced in both the initial setup and in maintenance because ....

....tasks. The CORBA specifications do not define any built in management support. Systems management is currently treated at the facilities layer within the Object Management Architecture (OMA) 19] which is the framework of CORBA. The specifications so far called Common Management Facilities (XCMF) [15] focus on support for policydriven objects. To date, low level management support, such as the performance instrumentation [4] specified for the OSF Distributed Computing Environment (DCE) is missing (see [21] for discussion) It is therefore up to ORB vendors and application developers to what ....

....especially when the target application is a legacy one, therefore difficult to maintain and evolve. Further on, a basic requirement in Internet based computing is that the various components must be operated and administered by their local authority, and not by a global administrative authority [33]. As a result, CORBA and DCOM are better suited for Intranet under a common administration authority. Here, we should mention the emerging Web Interface Definition Language (WIDL) 34] Based on XML [35] WIDL defines interfaces to Web data and services, enabling automatic and structured Web ....

It is especially the combination of Java and CORBA that is receiving much attention [8].

In this respect, a perhaps more interesting development is the proposed HTTP ng protocol [27] the goal of which is to present a new object based protocol for the Web. ....

....power than either technology does alone. A robust distributed architecture can be created using Java as programming language, Java applets to provide user interfaces, and CORBA as an integration technology. It should be noted that there are other types of middleware technology besides Java CORBA (Evans Rogers 1997). Other technologies such as HTTP CGI approach and ActiveX DCOM (Orfali Harkey 1997) are also used for developing intranet and Internet based applications. It is recognized that the HTTP CGI approach may be adequate when there is no need for sophisticated remote server capabilities and no data ....

....intranet and Internet based applications. It is recognized that the HTTP CGI approach may be adequate when there is no need for sophisticated remote server capabilities and no data sharing among databases is required. Otherwise, Java CORBA approach offers several advantages over HTTP CGI [14]. We note also that the CORBA s IIOP and HTTP can run on the same network as both of them uses the Internet as the backbone. Also, the interoperability between CORBA and ActiveX DCOM is already a reality with the beta version of Orbix COMet Desktop [29] Thus, the access to Internet databases ....

....for supporting distributed multiuser applications, especially after the introduction of Java. In fact, the WWW can be seen as a programming platform to integrate Internet based services and multiuser applications in which proactive or reactive processing is required, like groupware or workflow [Evans and Rogers 1997; Chen and Cowie 1997] In this paper we investigate how the WWW software architecture integrated by Java should be used to design distributed multiuser applications. Java is quite effective for this kind of applications, because it offers a uniform software platform to implement software running ....

....applications on top of the Web. Web browsers supporting Internet programming languages such as Java allow activity at user interface level in the form of applets. However, languages like Java need integrated middleware (e.g. CORBA) to coordinate activities tied to multiple, distributed clients [3]. Coordination has to be centralized at some server to which all users participating in an application have to connect to. Thereby, the activity located at the browser does not really make the application distributed, as applets at the browser cannot connect to other applets providing services to ....
