Introduction/Background

• Original HTML content on the web was largely static HTML pages.
• CGI scripts were the first way of generating HTML pages with dynamic content.
• Servlets are Java programs that run within a web server, or within a web application server.
  • There is a special Servlet API.
  • Servlets work hand-in-hand with databases, JavaBeans, components, and JSPs.
• JSPs are a combination of HTML and Java code.
• JSPs are a form of servlets; that is, they are compiled into servlets behind the scenes. In practice however, they appear quite different, and appear like a combination of HTML and Java code.
• In practice, JSPs should be approximately 90% HTML code and 10% Java code.
