All Implemented Interfaces:

DynaTag, Tag

public class SetPropertiesTag
extends MapTagSupport

A tag which sets the bean properties on the given bean. So if you used it as follows, for example using the <j:new> tag.

 <j:new className="com.acme.Person" var="person"/>
 <j:setProperties object="${person}" name="James" location="${loc}"/>
 

Then it would set the name and location properties on the bean denoted by the expression ${person}.

This tag can also be nested inside a bean tag such as the <useBean> tag or a JellySwing tag to set one or more properties, maybe inside some conditional logic.
