Defining the Custom Component Tag in a Tag Library Descriptor
To define a tag, you need to declare it in a tag library descriptor (TLD), which is an XML document that describes a tag library. A TLD contains information about a library and each tag contained in the library. TLDs are used by a Web container to validate the tags. The set of tags that are part of the HTML render kit are defined in the
html_basic
TLD.The custom tags
image
,area
, andmap
, are defined incomponents.tld
, which is stored in thecomponents/src/components/taglib
directory of your installation. Thecomponents.tld
defines tags for all of the custom components included in this release.All tag definitions must be nested inside the
taglib
element in the TLD. Each tag is defined by atag
element. Here is the tag definition of themap
tag:<tag> <name>map</name> <tag-class>cardemo.MapTag</tag-class> <attribute> <name>id</name> <required>true</required> <rtexprvalue>false</rtexprvalue> </attribute> <attribute> <name>currentArea</name> <required>true</required> <rtexprvalue>false</rtexprvalue> </attribute> </tag>At a minimum, each tag must have a
name
(the name of the tag) and atag-class
(the tag handler) attribute. For more information on defining tags in a TLD, please consult the Tag Library Descriptors section of this tutorial.
