Servlets are an exciting and important technology that ties Java to the Web, allowing programmers to write Java programs that create dynamic web content.
Java Servlet Programming covers everything Java developers need to know to write effective servlets. It explains the servlet lifecycle, showing how to use servlets to maintain state information effortlessly. It also describes how to serve dynamic web content, including both HTML pages and multimedia data, and explores more advanced topics like integrated session tracking, efficient database connectivity using JDBC, applet-servlet communicaton, interservlet communication, and internationalization. Readers can use the book's numerous real-world examples as the basis for their own servlets.
The second edition has been completely updated to cover the new features of Version 2.2 of the Java Servlet API. It introduces chapters on servlet security and advanced communication, and also introduces several popular tools for easier integration of servlet technology with dynamic web pages. These tools include JavaServer Pages (JSP), Tea, XMLC, and the Element Construction Set.In addition to complete coverage of 2.2 specification, Java Servlet programming, 2nd Edition, also contains coverage of the new 2.3 final draft specification.
Jason Hunter is Senior Technologist with CollabNet, a company that provides tools and services for open source style collaboration. In addition to authoring Java Servlet Programming, he is publisher of Servlets.com, creator of the com.oreilly.servlet library, a contributor to the Apache Jakarta project that creates Tomcat (starting on the project when it was still Sun internal), a member of the expert groups responsible for Servlet/JSP and JAXP API development, and he holds a seat on the JCP Executive Committee overseeing the Java platform, as a representative of the Apache Software Foundation. He also writes columns for JavaWorld, and speaks at many programming and open source conferences. Most recently he co-created the open source JDOM library to enable optimized Java and XML integration, and he leads the expert group responsible for JDOM development. Jason graduated summa cum laude from Willamette University (Salem, Oregon) in 1995 with a degree in computer science. He began programming in Java in the summer of 1995 and has been involved with servlets and related server-side technologies since December 1996. If by some miracle you don't find him at work, he's probably out hiking in the mountains. William Crawford has been developing web-based enterprise applications since 1995, including one of the first web-based electronic medical record systems (at Children's Hospital in Boston) and some of the first enterprise-level uses of Java. He has consulted for a variety of institutional clients, including Boston Children's Hospital, Harvard Medical Center, numerous startups and several Fortune 500 companies. Prior to an acquisition he was CTO of Invantage, Incorporated in Cambridge, MA. He received a degree in history and economics from Yale University. He is the co-author of Java Servlet Programming, 2nd Edition, Java Enterprise in a Nutshell, 2nd Edition, and two forthcoming O'Reilly titles. Will is currently Principal Software Architect at Perceptive Informatics, Inc.Massachusetts, provider of software and services to the pharmaceutical industry.
