calling a servlet from ajax in portlets

[archanagp]

Hi,

I am trying to develop a portlet which has a javascript function which uses ajax to call a servlet in the server.
The portlet I am trying to develop is in websphere application developer.
My servlet name is Ajax.

<script language="javascript" type="text/javaScript">
  var PATH = "<%= request.getContextPath() %>";
  var Ajax_SERVLET = PATH + "/Ajax";
  function showProduct(str)
  {    
  alert("Inside the function");
  xmlHttp=GetXmlHttpObject();
    if (xmlHttp==null)
      {
      alert ("Your browser does not support AJAX!");
      return;
      } 
    var url=Ajax_SERVLET;
    alert(url);
    xmlHttp.onreadystatechange=stateChanged;
    xmlHttp.open("GET",url,true);
    xmlHttp.send(null);
}

please help me as soon as possible..

Hi Archana,
This is Chirag here. I am also trying to do the same thing but still not gettting solution. I tried to call the portlet and to some extent I a have succeeded but after that not able to display the output again on JSP. One of the link says that you cannot make a direct Ajax call to portlets as it renders the portal content also along with the target portlet.
Well you can contact me on my personal id chirag.rana@red iffmail.com
