Core Web Programming
However, when Marty went shopping for texts over the next semester or two, he got a rude surprise. Despite the availability of good books in most of the individual areas he wanted to cover, Marty found that he needed three, four, or even five separate books to get good coverage of the overall material. Similarly, for his day job, Marty was constantly switching back and forth among the best of the huge stack of books he had accumulated and various on-line references. Surely there was a better way. Shouldn't it be possible to fit 85 percent of what professional programmers use in about 35 percent of the space, and get it all in one book?
That was the genesis of the first edition ofCore Web Programming. The book was very popular, but the industry has been rapidly moving since the book's release. Browsers moved from HTML 3.2 to 4.0. The Java 2 platform was released, providing greatly improved performance and graphics libraries suitable for commercial-quality applications. JSP 1.0 came along, resulting in an explosion of interest in both servlets and JSP as an alternative to CGI and to proprietary solutions like ASP and ColdFusion. XML burst upon the scene. The server equalled or even surpassed the desktop as the biggest application area for the Java programming language.
Wow. And demand has only been growing since then. Although readers were clamoring for a new edition of the book, it was just too much for Marty to handle alone. Enter Larry Brown, with broad development and teaching experience in Java and Web technologies, and with particular expertise in the Java Foundation Classes, multithreaded programming, RMI, and XML processing with Java. Larry teamed up with Marty to totally update the existing material to HTML 4, CSS/1, HTTP 1.1, and the Java 2 platform; to replace the CGI sections with chapters on servlets 2.2 and JSP 1.1; and to add completely new sections on Swing, Java 2D, and XML processing with JAXP, DOM Level 2, SAX 2.0, and XSLT. They even got a little bit of sleep along the way.
We—Marty and Larry—hope you find the result enjoyable and useful!Real Code for Real Programmers
A word of caution, however. Nobody becomes a great developer just by reading. You have to write some real code too. The more, the better. In each chapter, we suggest that you start by making a simple program or a small variation of one of the examples given, then strike off on your own with a more significant project. Skim the sections you don't plan on using right away, then come back when you are ready to try them out.
Web pages are created with HTML, the HyperText Markup Language. HTML lets you mix regular text with special tags that describe the content, layout, or appearance of the text. These tags are then used by Web browsers like Netscape Navigator or Microsoft Internet Explorer to format the page. This first part of the book covers the following topics in HTML.
Java is a powerful general-purpose programming language that can be used to create stand-alone programs as well as ones that are embedded in Web pages. The following Java topics are covered.
Programs that run on a Web server can generate dynamic content based on client data. Servlets are Java technology's answer to CGI programming and JSP is Java's answer to Active Server Pages or ColdFusion. The following server-side topics are discussed.
