Ajax URL with Struts J2

[Akshay Ahooja]

Hi,

I am using Struts Bridge in J2, with AJAX components.

For regular links, using <html:link works out fine, however for Ajax, I have
a validate function:

   function validate()
   {

       var idField= document.getElementById("taskid");
       var url = "validate?id=" + escape(idField.value);
       if (window.XMLHttpRequest) {
           req = new XMLHttpRequest();
       }
       else {
           req = new ActiveXObject("Microsoft.XMLHTTP");
       }


       req.open("GET", url, true);
       req.onreadystatechange=callback;
       req.send(null);
   }

This validate function has a url that it uses. It works fine as a WebApp but
gives a javascript "Object Expected" error when ran in J2.I assume this is
because of the URL itself. How do I call this URL within this function? (Is
GET ok or does it need to be POST? - I do not wish to use POST as it will
limit my application, and plus this does not affect the server side
application state.)

My URI in web.xml is:

    <servlet>
       <servlet-name>validate</servlet-name>
       <servlet-class>com.svvc.rap.ValidateServlet</servlet-class>
       <url-pattern>*.do</url-pattern>
   </servlet>
   <servlet-mapping>
       <servlet-name>validate</servlet-name>
       <url-pattern>/validate</url-pattern>
   </servlet-mapping>
