- <h1>JSP 2.0 Examples - Repeat SimpleTag Handler</h1>
- <hr>
- <p>This tag handler accepts a "num" parameter and repeats the body of the
- tag "num" times. It's a simple example, but the implementation of
- such a tag in JSP 2.0 is substantially simpler than the equivalent
- JSP 1.2-style classic tag handler.</p>
- <p>The body of the tag is encapsulated in a "JSP Fragment" and passed
- to the tag handler, which then executes it five times, inside a
- for loop. The tag handler passes in the current invocation in a
- scoped variable called count, which can be accessed using the EL.</p>

- <mytag:repeat num="5">
- Invocation ${count} of 5<br>
