- Tag Reuse
Tag libraries must follow important conventions for initializing
tag fields. The JSP specification lets a JSP container, like Resin,
reuse tag handler instances for efficiency and performance.
Because this optimization restricts how tags can use fields,
even experienced developers will benefit from this tutorial.
- Empty Tag
The simplest kind of tag does not evaluate it's contents.
- Tag Attributes
Tags become more useful once you add attributes. This example creates
- Mail Tag
Body tags can grab JSP results and send them to an entirely different
location. It's easy to create a custom tag that sends part of a JSP to
a survey account. The required attribute
will specify the
mail address for the mail and specifies the subject. The
enclosed JSP contains the body of the mail.
- Tag Files
JSP 2.0 introduces XML-based tag files. Instead of having to write
Java code for custom tags, applications can use XML or JSP syntax for
their tags. Tag files do not require .tld files,
making development simpler.
