HI I am trying to pass a value from dropdown list on onchange event fo the dropdown in a jsp page through AJAX to servlet. The servlet then returns the value back to the jsp page and displays it in dropdown list.

the problem I am facing is that the value returned is null. though in the servlet the value is set but when I pass the value to jsp, the value is null. somewhere I am passing the value properly. could someone please help. It's important. thnaks in advance.

here is the code for that:

inputPage.jsp

    {
    alert("str"+str);
    if (str=="")

      return;
      }  
    if (window.XMLHttpRequest)
      {// code for IE7+, Firefox, Chrome, Opera, Safari
      xmlhttp=new XMLHttpRequest();
      }
    else
      {// code for IE6, IE5

        {
        alert("xmlhttp.status"+xmlhttp.status);

        document.getElementById("txtHint").innerHTML=xmlhttp.responseText;




        }
      }
      alert("str1"+str);
    xmlhttp.open("GET","/Tester.html?q="+str,true);
    xmlhttp.send();

What you are doing in the servlet is that you are setting the 'tagValue' as an attribute in the request and than forwarding the request.
But for AJAX requests all you have to do is just send the 'tagValue' on the response output stream

You should do something like this in your servlet,

.......
public void doGet(HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException {
System.out.println("in servlet#########################: doGet() method");
PrintWriter out = response.getWriter();

tagName = request.getParameter("q");

if(tagName.equals("2")){
     tagValue = getInitParameter("2"); 
     out.println(tagValue); //This will send the data as a response text to AJAX request
}

String tagName = "";
String tagValue ="";

...............
}

You can also create a XML as a String object and send it on the response output stream and in the javascript callback function you can read it with xmlhttp.responseXML

A nice introductory tutorial can be found at
http://www.oracle.com/technetwork/articles/javaee/ajax-135201.html

Hope this helps

Hi Thanks for replying back...I am new to this forum and was not sure if anyone's going to reply back.So I saw a post on this forum and actly changed my code according to that...but still I am facing the problem. The value of 'tagValue' is not getting displayed on the page. I have included your change too. Could you please take a look at the new code and suggest me whats wrong.
If I do a sysout on jsp page to see the value of 'userBean.getTagValues()', I am getting the expected values. but hte values are not just not getting displayed on the page. Is it the problem of the dropdown list..please advice.
I am new to JSP , servlets and AJAX. I would really appreciate if you could go throught the new code and give some advice. Thanks in advance.

This program helps in creating a jsp page in which 2nd dropdown is populated based on the selected value of the first dropdown using AJAX. The values of the second dropdown are fetched from the database by calling a servlet.then the selected values are submitted and the result is printed on the same jsp page. however on fetching the result, the inputPage.jsp is submitted again due to which the selected values of the dropdown are not prepopulated. in order to avoid that currently I am displaying the results on submission on another jsp page called transInput.jsp. In case anybody can help me on that, it would be great. thanks
