Chapter 10. Creating Custom Tags

Welcome to Day 10—yesterday, you took a look at using and creating custom tags, and today you'll get more of the story. Creating a custom tag is actually a very large topic in JSP, which is why two days are dedicated to them. Today, you'll learn how to:

• Create a simple tag that inserts text into a Web page

• Use the pageContext object

• Support custom tag attributes

• Create iterator tags

• Make custom tags cooperate, using pageContext attributes

• Work with scripting variables to pass data between JSP code and custom tag code
