taglib

Syntax:

<tablib uri="myURI" prefix="my"/>

It 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 toLowerCase function.

<taglib uri="http://www.zkoss.org/dsp/web/core" prefix="c"/>
<action pattern="/hello" method="c:toLowerCase(request.method)" class="foo.Hello"> 
...

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"/>

For more information about the syntax of a custom taglib, please refer to ZUML Reference.

uri

The prefix Attribute

A prefix used to identify functions defined in this taglib file. The prefix could be any non-empty string.
