As usual, when learning a new technology, the first application to write is a "Hello World" style application. To continue this tradition, I've written a very simple Hello World JSF application. After setting up the Faces servlet as described in my previous post, I've written a simple JSP page called hello.jsp which has the following contents:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<f:view>
<h:outputText value="Hello World" />
</f:view>
</body>
</html>
This simple JSP page specifies that the 2 JSF taglibs "core" and "html" are to be used and specifies their appropriate prefixes. The HTML is pretty standard up until the <f:view> tag. This tag tells the container we are going to start using JSF components. Inside this tag, the outputText component is used to print out the text "Hello World" to the browser.
This trivial application is started by pointing the browser to http://localhost:8080/LearningJSF/hello.jsf
