Description
Developing Java Server Pages teaches JSP programming, with emphasis on techniques that allow programmers to get the job done quickly and efficiently. This book shows you how JSP, the next chapter in the evolution of Java as a server side development language, is used and how it can be used. Workarounds in advice and code are explored to provide practical and realistic solutions to problems. Other technologies are also introduced, including Servlets, the Java language, JDBC, and beans. Using extensive examples, and a hands-on approach, authors Paul Colton, Andre Lei, and Scott Stirling present the most important topics for web developers, including security, database interaction, custom tags and scalability. All examples are based on hard earned, real-world experience.
