JSP technology -- friend or foe?A critical look at JavaServer Pages servlets as a viable presentation technology Brett McLaughlinEnhydra Strategist, Lutris TechnologiesOctober 2000 An old Java technology hand and new Enhydra partisan, the author urges developers to consider alternatives to JavaServer Pages JSP servlets when choosing an approach to coding Web applications. JSP technology, part of Suns J2EE platform and programming model, serves as a solution to the common dilemma of how to turn drab content into a visually appealing presentation layer. The fact is, Web developers arent uniformly happy with JSP technology. Since many variations on the Sun technology are now available, you can choose from a number of presentation technologies. This article takes an in-depth look at JSP coding and explores some attractive alternatives. Presentation technology was designed to transform plain ol raw Web content into content wrapped in an attractive presentation layer. JavaServer Pages JSP technology, Suns presentation model and part of the J2EE platform, has received significant attention. There are both advantages and disadvantages to using JSP technology, and Web developers should be aware of the good and the bad -- and know that they dont have to be limited to this single technology. In fact, these days a number of presentation technologies are available. This article begins by defining the problems presentation technologies were designed to solve. It then examines the specific strengths and weaknesses of the JSP model. Finally, it introduces some viable alternatives to Suns presentation technology.
