Syntax:
<?tablib uri="myURI" prefix="my"?>
This directive is used to load a taglib file, which defines a set of static methods that can be used in EL expressions (so called EL functions).
For example, we could load functions defined in the built-in TLD files identified as http://www.zkoss.org/dsp/web/core, and then use the l function.
<?taglib uri="http://www.zkoss.org/dsp/web/core" prefix="c"?>
<window title="${c:l('my.title')}">
...
</window>
If you want to load a TLD file from your Web application, you can specify the path directly. For example, suppose you have a custom TLD at /WEB-INF/tld/my.tld
, then you could specify it as follows.
<?taglib uri="/WEB-INF/tld/my.tld" prefix="my"?>
<listbox>
<listitem label="${each.name}" forEach="${my:getCustomers()}"/>
<!-- assume there is a function called getCustomers -->
</listbox>
The syntax of a taglib document is described in the subsection:
uri
[Required][EL is not allowed]
A URL of the taglib file. Unlike other URL and URI, it doesn't interpret ~ or * specially. And, the page and the taglib files it references must be in the same Web application.
prefix
[Required]
A prefix used to identify functions defined in this taglib file. The prefix could be any non-empty string.
