The next section to examine is the
<tag>
section. It describes the name of the tag and its asso-
ciated tag handler. It also says that the
bodycontent
for this tag is empty.
The next step is to copy this
tld
into a directory that can be referenced in the Web applica-
tion's deployment descriptor. For this example, create a directory
<SERVER_ROOT>/webapps/djs/WEB-INF/tlds/
and copy the
tld
into it.
The final step to deploy your tag library is to add the following section to your application's
web.xml
file.
<taglib>
<taglib-uri>/djs</taglib-uri>
<taglib-location>/WEB-INF/tlds/taglib.tld</taglib-location>
</taglib>
Now you can see your new tag in action. Listing 19.3 contains the source for the JSP that will
use your
Hello
tag.
