Chapter 6. Formatting Data with Tags
JSTL provides several tags that greatly simplify the formatting and parsing of data. Tags are provided that allow you to format numbers, percents, dates, and currencies. By using these tags, you can fine-tune the output of your data, without the need for customized display programming.
Web applications must frequently process data entered by a user. Data from a user always arrives as a string. However, this string is often a number, date, percentage, or other data type. JSTL provides parsing tags that enable you to take the strings a user enters and parse them into other data types.
In this chapter, we examine both of these issues. We provide several examples that illustrate practical application of data formatting and parsing. We begin by examining the process of data formatting.
