public class ServletActionRedirectResult
extends ServletRedirectResult
implements com.opensymphony.xwork2.util.reflection.ReflectionExceptionHandler

This result uses the ActionMapper provided by the ActionMapperFactory to redirect the browser to a URL that invokes the specified action and (optional) namespace. This is better than the ServletRedirectResult because it does not require you to encode the URL patterns processed by the ActionMapper in to your struts.xml configuration files. This means you can change your URL patterns at any point and your application will still work. It is strongly recommended that if you are redirecting to another action, you use this result rather than the standard redirect result. See examples below for an example of how request parameters could be passed in. This result type takes the following parameters:

• actionName (default) - The name of the action that will be redirected to.
• namespace - Used to determine which namespace the action is in that we're redirecting to. If namespace is null, the default will be the current namespace.
• suppressEmptyParameters - Optional boolean (defaults to false) that can prevent parameters with no values from being included in the redirect URL.
• parse - Boolean, true by default. If set to false, the actionName param will not be parsed for Ognl expressions.
• anchor - Optional. Also known as "fragment" or colloquially as "hash". You can specify an anchor for a result.

Example:

 
 <package name="public" extends="struts-default">
     <action name="login" class="...">
         <!-- Redirect to another namespace -->
         <result type="redirectAction">
             <param name="actionName">dashboard</param>
             <param name="namespace">/secure</param>
         </result>
     </action>
 </package>

 <package name="secure" extends="struts-default" namespace="/secure">
     <-- Redirect to an action in the same namespace -->
     <action name="dashboard" class="...">
         <result>dashboard.jsp</result>
         <result name="error" type="redirectAction">error</result>
     </action>

     <action name="error" class="...">
         <result>error.jsp</result>
     </action>
 </package>

 <package name="passingRequestParameters" extends="struts-default" namespace="/passingRequestParameters">
    <!-- Pass parameters (reportType, width and height) -->
    <!--
    The redirectAction url generated will be :
    /genReport/generateReport.action?reportType=pie&width=100&height=100#summary
    -->
    <action name="gatherReportInfo" class="...">
       <result name="showReportResult" type="redirectAction">
          <param name="actionName">generateReport</param>
          <param name="namespace">/genReport</param>
          <param name="reportType">pie</param>
          <param name="width">100</param>
          <param name="height">100</param>
          <param name="empty"></param>
          <param name="suppressEmptyParameters">true</param>
          <param name="anchor">summary</param>
       </result>
    </action>
 </package>
