In my web-app, after a form validation, perform an Ajax request to my Struts action:

 $.ajax({
                url: "**viewResult**",
                type:"POST",
                data: "TEST",
                contentType: "application/json; charset=utf-8",
                success: function(res, textStatus, jqXHR) {

.....

Ajax request is successfully performed as well as my execute method in action so I would expect to be redirected to the specified page but this doesn’t happen. Below my struts.xml :

I've already tried to use

${url}

“`
and

  
         <action name="viewResult" class="comparatorProject.navigator.actions.ViewResultAction" method="execute" >
            <result name="success" type="dispatcher">
             <param name="location">jsp/viewResult.jsp</param>
             </result>
        </action>    ```
