Conventions Used in This Book

Italics are used for:

• Pathnames, filenames, program names, compilers, options, and commands

• New terms where they are defined

• Internet addresses, such as domain names and example URLs

Constant width is used for:

• Anything that appears literally in a JSP page or a Java program, including keywords, datatypes, constants, method names, variables, class names, and interface names

• Command lines and options that should be typed verbatim on the screen

• All JSP and Java code listings

• HTML documents, tags, and attributes

• XML element and attribute names

• Maven goals such as java:compile

Constant width italics are used for:

• General placeholders that indicate that an item is replaced by some actual value in your own program

Constant width bold is used for:

To indicate a continued command line, we used the convention appropriate to the operating system: \ for Unix, and ^ for a Windows DOS shell.
