This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Everyone says E-commerce is the in-thing today. I have basic questions on this 1> Can an e-commerce application be done just by using servlets or server-side programming or applets and windows programming is also necessary. 2> What is E-commerce exactly? These questions may sound stupid but they say "Curiosity kills the cat "

1> Can an e-commerce application be done just by using servlets or server-side programming or applets and windows programming is also necessary. Both ... Servlets can be replaced by CGI programs written in Perl, C++ etc. But applet programming, I believe, is MANDATORY for succes of e-commerce 2> What is E-commerce exactly? Carry business electronically -- buy, sell and even have a virtual office - GREAT , no need to pay for office space- VoIP, video conferencing -- all can be achieved and can form part of E-commerce.
E-commerce is simply any form of commerce (buying, selling, marketing etc.) done using the internet (web, email, news, chat etc...) E-commerce operations are often divided into two broad categories; "consumer" and "B2B". Consumer e-commerce is any form of e-commerce used directly by members of the public. Such systems usually include at least a web site with catalogue and product details, and some way to buy product on line (typically via web forms). B2B (business-to-business) e-commerce is electronic commerce between businesses. This may take a similar form to customer e-commerce, but can also include more specialized server systems for other protocols (CORBA etc). B2B e-commerce is sometimes also taken to include things like the replacement of fax ordering and invoicing with automatic generation and processing of email messages. Many successful e-commerce organizations use purely server-side software (Amazon.com, for example) so Applets are not necessary. The server-side software can be written in any language, but Java Servlets are a fairly popular choice, as is ASP. Early e-commerce systems tended to be based on CGI, but CGI is not very scaleable, so larger systems are abandoning CGI to move to more specific technology.
