This in-depth tutorial acquaints HTML and Java programmers with the world of JSP tags -- Java components that open up JSP development to the everyday content developer (the HTML programmer) and improve code reuse and separation between presentation and business logic. Using real-world tags, it guides the novice through practical JSP applications, such as performing iterations and accessing databases, EJBs, e-mail systems, and Java Beans, and demonstrates how tags can be used in the context of e-commerce applications and WAP that work with cellular phones. Included are numerous short examples that can be reused to add simple and powerful dynamic features to Web sites.
