technology for web application development that has received a great deal of attention since it was first announced in 1999 Since then, it has gone through three revisions This book covers the 2.0 version of the specification Why is JSP so exciting? One reason is that JSP is Java-based, and Java™ is well suited for enterprise computing In fact, JSP is a key part of the Java 2™ Enterprise Edition (J2EE) platform and can take advantage of the many Java Enterprise™ libraries, such as JDBC™, JNDI™, and Enterprise JavaBeans™ Another reason is that JSP supports a powerful model for developing web applications that separates presentation from processing Understanding why this is so important requires a bit of a history lesson In the early days of the Web, the only tool for developing dynamic web content was the Common Gateway Interface (CGI) CGI outlined how a web server made user input available to a program, as well as how the program provided the web server with dynamically generated content to send back CGI scripts were typically written in Perl (In fact, Perl/CGI scripts still drive numerous dynamic web sites.) However, CGI is not an efficient solution For every request, the web server has to create a new operating-system process, load a Perl interpreter and the Perl script, execute the script, and then dispose of it when it's done To provide a more efficient solution, various alternatives to CGI have been added to programmers' toolboxes over the last few years: FastCGI, for example, runs each CGI program in an external permanent process (or a pool of processes) In addition, mod_perl for Apache, NSAPI for Netscape, and ISAPI for Microsoft's IIS all run server-side programs in the same process as the web server itself While these solutions offer better performance and scalability, each one is supported only by a subset of the popular web servers The Java Servlet API, introduced in early 1997, provides a solution to the portability issue However, all these technologies suffer from a common problem: HTML code embedded inside programs If you've ever looked at the code for a servlet, you've probably seen endless calls to out.println( ) that contain scores of HTML tags For the individual developer working on a simple web site, this approach may work fine, but it makes it difficult for people with different skills to work together to develop a web application This embedded HTML code is becoming a significant problem As web sites become increasingly complex and more critical to an organization's success, the appearance and usability of the web interface becomes paramount New client technologies, such as client-side scripts and DHTML, are used to develop more responsive and interactive user interfaces, stylesheets can make it easier to globally change fonts and colors, and images make the interface more appealing At the same time, server-side code is getting more complex, and the demands for reliability, performance, and fault tolerance are increasing The increasing complexity of web applications requires a development model that allows people with different skills to cooperate efficiently JSP provides just such a development model, allowing web page authors with skills in areas such as client-side technologies and usability to work in tandem with programmers who are experienced in server-side technologies, such as multithreading, resource pooling, databases, and caching While there are other technologies, such as ASP, PHP, and ColdFusion, that support similar development models, none offer all the advantages of JSP [ Team LiB ] This document is created with a trial version of CHM2PDF Pilot http://www.colorpilot.com [ Team LiB ] What's in This Book This edition of the book covers Version 2.0 of the JSP specification, which was released late 2003 It also covers the related JSP Standard Tag Library (JSTL) specification, Version 1.1, also released late 2003 You will learn how to use all the JSP standard elements and features, including elements for accessing JavaBeans components; separating the processing over multiple pages to increase reusability and simplify maintenance; and sharing information between pages, requests, and users You will also learn how to use JSTL for tasks such as conditional processing, integration of database data, internationalization, and XML processing, as well as how to develop your own custom components for tasks not covered by the standard components The examples in this book guide you through solutions to common JSP design problems, from basic issues, such as retrieving and validating user input, to more advanced areas, such as developing a database-driven site, authenticating users, providing personalized content, caching data for better performance, and implementing internationalization The last part of the book describes how you can combine JSP with other Java technologies; in particular, I describe the combination of JSP and servlets using the popular Apache Struts framework, and provide an overview of how JSP fits into the larger scope of J2EE [ Team LiB ] This document is created with a trial version of CHM2PDF Pilot http://www.colorpilot.com [ Team LiB ] Readers of the Second Edition If you've read the second edition of JavaServer Pages, you'll notice that, in this edition, even more of the custom components used in the previous edition have been replaced in favor of the equivalent standard components from JSTL —a specification I've been lucky enough to contribute to and help shape the standard based on many of the ideas explored in the first and second editions You'll also notice that all the chapters have been modified (some more than others) to cover the new features in the latest versions of the JSP and JSTL specifications A brand new chapter has been added to describe how to develop custom tag libraries using the new tag file format, and the chapter about custom library development using Java has been substantially expanded to cover the new, simplified tag handler API as well as the new mechanism for including Expression Language functions in a tag library All chapters have also been updated to cover the features and clarifications added in the Servlet 2.4 specification on which JSP 2.0 is based Here's a brief summary of the primary changes in all the specifications covered in this book: Incorporation of the Expression Language (EL), first introduced by the JSTL specification in the JSP specification (making it available to all standard and custom components as well as in template text) The EL extended with a function call mechanism and a set of common functions added to JST Addition of the ability to develop custom tag libraries as tag files (text files with JSP elements) as well as a new, simplified tag handler Java API, and various new tag library features such as support for a dynamic attribute list and executable fragment attributes More flexible rules for JSP pages written as XML documents, and support for the JSP directives and scripting elements of XML syntax in regular JSP pages New JSP standard elements, primarily to allow more flexible attribute value assignments and to support the new tag file format and XML format enhancements Access to more information in a JSP error page and adjustment of the attribute names to match the Servlet specification Stricter container requirements to improve syntax error reporting and debugging support for JSP pages XML Schema-based deployment descriptors for all specifications with new configuration options, including automatic include of page segments, page encoding specification, scripting element disabling, and more for JSP Addition of a new request listener component type and filters that can be applied to internal requests Deprecation of the single thread model for both servlets and JSP New JSTL tag library URIs and a few attribute name changes for the XML library [ Team LiB ] This document is created with a trial version of CHM2PDF Pilot http://www.colorpilot.com [ Team LiB ] [SYMBOL] [A] [B]
