Forwarding using mapping.findForward in Struts 1.2

public class MyAction extends Action
{   
    public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {

        String status="success";
        HttpSession session = request.getSession(true);
        System.out.println("My Action---setting key value");
        request.getSession().setAttribute("key1","check");

        //response.sendRedirect("http://localhost:9080/FamiliarPortal/jsp/inicio.jsp");
        return mapping.findForward(status); 

    }
}

In Struts-config.xml, the following is added:

<action path="/myAction" type="iusa.ubicacel.actions.MyAction" validate="false" >
         <forward name="success" path="/jsp/inicio.jsp"/>       
</action>

In web.xml, the following is added:

<servlet>
        <servlet-name>GetFAP</servlet-name>
        <servlet-class>iusa.ubicacel.actions.map.GetFAP</servlet-class>
    </servlet>
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
<servlet-mapping>
        <servlet-name>GetFAP</servlet-name>
        <url-pattern>/GetFAP</url-pattern>
</servlet-mapping>

In inicio.jsp, the following is added:

<BODY onload="requestXML('<%=reqURL %>');">

<table border="0" cellspacing="0" cellpadding="0" align="center">
    <tr>
        <td align="center" valign="middle">
            <div id="mapdiv" style="width: 1000px; height:700px"></div> 
        </td>
    </tr>
</table>
</BODY>

The function requestXML is as follows:

function requestXML(reqURL) 
{   
    alert("calling requestXML"+reqURL);
    var url = "../GetFAP?requestURL=" + reqURL;
    alert("calling requestXML"+url);
    xmlhttpUbi = FAPXMLHttpRequest();
    xmlhttpUbi.open("POST", url, true); // async
    alert("after calling");
    xmlhttpUbi.onreadystatechange = obtainFAPLocation;
    xmlhttpUbi.send(null);
}

The above code is not calling the GetFAP servlet when using mapping.findForward. But when I used response.sendRedirect("entire jsp path") it is calling the servlet.

Can anyone tell me what I am doing wrong here?

You are using a relative URL instead of an absolute URL.

When you render the JSP directly, the ../GetFAP mapping works because you must move "up" a level up from the /jsp directory.1

When you render the JSP from an action, you're moving a level up from the action's path, i.e., there's no more /jsp directory in the URL to move up from.

This is among the many reasons why using relative paths can be a bad idea.

1 JSP files should live in the WEB-INF directory to avoid direct client access.
