8.8 Other Useful Tag Libraries

The Struts custom tags aren't the only tag libraries
that work with Struts applications. Although some of the Struts tags
make it very easy to use certain facets of the framework, other tags
can assist you in developing applications and help to reduce the
development time for a project.

We will mention only two of the more popular locations at which you
can find additional tag libraries, but many other sites and vendors
provide free or low-cost tag libraries too. You should always check
to see if the tag you need already exists or if
there's one that's close enough for
you to simply extend or modify.

8.8.1 The Jakarta Taglibs Project

One of the best resources is another Jakarta project named Taglibs.
The goal of the Taglibs project is to provide an open
source repository for JSP custom tag libraries and web publishing
tool extensions.

There are around 25 separate tag libraries in the Taglibs project,
each of which provides some unique functionality that most web
applications need to perform sooner or later. The tag libraries are
free and provide the source code, which allows you to not only get a
better understanding of how to develop JSP tags but also to modify or
extend the tags as your application dictates.

There's no sense in listing the available tags, as
new ones are added regularly. The best idea is to check the site
itself. You can find the Taglibs project on the Jakarta site at
http://jakarta.apache.org/taglibs.

8.8.2 JSPTags.com

Another useful web site that contains many
JSP tags is
http://jsptags.com. This site has
been around for several years and has many tag libraries that you can
use for free. It's also a great resource for other
web application information. Make sure to check this site as well
before setting off to create your own tag. Somebody may have already
created the tag you need, saving you the development and testing
timealways a good thing.
