When We study mordern products and learn lately technologies, reviewing the context and history of the technologies and products is a neccessary step, just like if you want to learn mordern physics well, you have to read Einstein Autobiography which descripted the mordern physical history. So, fisrt, let's review IBM and E-commerce ( most of paragraphs quoted from IBM website)

Although the world economic is dropping now, which is shaking the development of e-commerce but e-commerce still is relatively new and its popularity among both individuals and businesses has grown rapidly.
the various businesses use the Web primarily to provide products, services, and information to their customers, suppliers, and employees, which are the main purposes of e-business.

Static HTML Time
When the first businesses moved onto the Web, it was enough for them to provide a few static Web pages that listed products and services for sale and provided a telephone number or address to order those products and services. Businesses that provided information services (like software companies) were among the first to enter this new frontier, and they often made their products, in the form of information or software, directly available for
downloading.
<a name=CGI></a>
CGI Time
As the Web matured and new technologies were developed, static Web pages were no longer sufficient. In response, businesses built active Web sites where customers can order
products directly, customers and suppliers can communicate with the business, and employees can communicate with each other. CGI and technologies related are the main stream application in active web pages at that time. As you see now, the CGI is decrepit by the Servlet, Perl has been replacing by Java since there is a complex tranfer contract in Perl.

Infrastructure
While the Web side of many businesses was changing rapidly, non-Web business systems also went through some major changes as application development spread into distributed
systems from mainframe systems. The Open Group's Distributed Computing Environment(DCE) and the Object Management Group's (OMG) Common Object Request Broker
Architecture (CORBA) were two major technologies that provided the infrastructure for these types of systems. As we see, RMI tech, is also the Distributed Computing Tech, it have the advantage of cheapness and robustness.
Until recently, Web and non-Web business systems remained largely detached from each other. The IBM e-business initiative and the WebSphere Family change that by enabling
businesses to integrate their Web-based systems with their non-Web systems, to produce a single enterprisewide business system. Further, the WebSphere Family is available in three different editions so that customers can approach the challenge of implementing e-business
solutions in several different ways.
