Documentation Conventions

File and directory paths are given in Windows format (with backslashes separating directory names). For Unix versions, the directory paths are the same, except forward slashes are used instead of backslashes to separate directories.

This guide uses URLs of the form: http://server.domain/path/file.html, where:

server is the name of the server where you are running the application.
domain is your internet domain name.
path is the directory structure on the server.
file is an individual filename.

The following table shows the typographic conventions used throughout Sun ONE documentation

Table 1  Typographic Conventions 

Typeface	Meaning	Examples
Monospaced	The names of files, directories, sample code, and code listings; and HTML tags	Open Hello.html file. <HEAD1> creates a top level heading.
Italics	Book titles, variables, other code placeholders, words to be emphasized, and words used in the literal sense	See Chapter 2 of the Migrating and Redeploying Server Applications Guide. Enter your UserID. Enter Login in the Name field.
