Conventions
In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text are shown as follows: "We can include other contexts through the use of the include directive."
A block of code is set as follows:
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page language="java" %>
<html >
<HEAD>
<TITLE>PACKT Login Form</TITLE>
<SCRIPT>
function submitForm() {
var frm = document. myform;
if( frm.j_username.value == "" ) {
alert("please enter your username, its empty");
frm.j_username.focus();
return ;
}When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page language="java" %>
<html >
<HEAD>
<TITLE>PACKT Login Form</TITLE>
<SCRIPT>
function submitForm() {
var frm = document. myform;
if( frm.j_username.value == "" ) {
alert("please enter your username, its empty");
frm.j_username.focus();
return ;
}Any command-line input or output is written as follows:
[INFO] Parameter: groupId, Value: com.packt [INFO] Parameter: artifactId, Value: spring-security-wicket [INFO] Parameter: version, Value: 1.0-SNAPSHOT
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "After clicking on submit we need to get an authenticated session."
