JavaServer Pages

JavaServer pages (JSP) enable Web developers to combine the flexibility of HTML with the power of Java components to capitalize on dynamic features for Web applications. The simplicity of JSP's component-based model, combined with the cross-platform power of Java, creates a Web development environment with enormous potential. Written by a key contributor not only to the JSP specification, but also to the JSP and Servlet reference implementations, the second edition of this comprehensive guide to JavaServer Pages shows you how to embed server-side Java in to Web pages, while also offering full access to other features such as JavaBeans, Enterprise JavaBeans (EJB), and JDBC database access. In addition, this book covers the new Java Standard Tag Library (JSTL) in detail - in fact, most of the examples are updated to use this new technology from Sun Microsystems, Inc. Filled with examples, this 2nd Edition is completely revised and updated to cover the changes in the 1.2 version of the JSP specifications, and includes coverage of the new JSTL Tag libraries-an eagerly anticipated standard set of JSP elements for the tasks needed in most JSP applications, as well as thorough coverage of
