Rendered Output:
5. Facelet define tag
This tag is used to define the name of the
content. This named content can be included
within a template. This tag is used within those
tags that allows templating like composition and
decorate tags. This tag takes one attribute
named “name” that is required to be included
when using this define tag. This name attribute
is required to be same as name attribute of
insert tag in the target template to include the
content specified in define tag with the same
name. For example, in the first define tag name
attribute is set to “face1”. Now look at the
code below in “definetemplate.xhtml” where we
have used insert tag with name attribute. This
name attribute is given value “face1”. So the
content within define tag, whose name attribute
value matches with the name attribute of the
insert tag i.e.”face1", will be included in the
“definetemplate.xhtml”.
