Custom WebWork Result Type

add following to a xwork.xml config file:

<?xml version="1.0" encoding="utf-8"?>
<result-types> <result-type name="mydispatch" class="com.company.portal.util.MyDispatch" default="true"/> <result-type name="my2dispatch" class="MyDispatch" default="true"/><!-- spring wire bean --> </result-types>

use this custom type in the action:

<?xml version="1.0" encoding="utf-8"?>
<action name="mydispatch" class="myPackage.barAction"> <result>foo.jsp</result> </action>

Actually can simply extend a webwork predefined resulttype for some purpose and override the conditionalParse and return a final location for the action. major methods in WebWorkSupport.java

/** * Implementation of the execute method from the Result interface.
This will call * the abstract method {[cite/t:@link] #doExecute(String,
