The JavaServer Pages (JSP) web framework introduced a great productivity boost for Java web developers over the Java Servlet API. When the JSP technology was introduced in 1999, it was Sun’s answer to PHP and ASP, which provided web developers with a quick way to create dynamic web content. JSPs contain a mix of XML and HTML but can also contain embedded Java code within scripting elements known as scriptlets. Indeed, JSPs are easy to learn and allow developers to quickly create dynamic content and use their favorite HTML editor to lay out nice-looking pages. JSP was introduced several years ago and still remains one of the most important Java web technologies available. Although JSP technology has changed over the years, there are still many applications using older JSP variations in the world today.
