xel-method

Syntax:

<xel-method prefix="..." name="..." class="..." signature="..."/>

It specifies an EL function that could be used in EL expressions. For example,

 <xel-method prefix="c" name="forName"
     class="java.lang.Class"
     signature="java.lang.Class forName(java.lang.String)"/>
 <action class="${c:forName('foo.MyAction')}">
...

Notice that the class attribute of an action definition could be a string, so the above statement is equivalent to the following:

<action class="foo.MyAction">
