callServer to call servlets, to update DCT values

Hi Techies,

We are facing the issue, while updating the DCT test box values.

Actually we have DCT with some text fields. We have make a call to servlet by using IWDatacapture.callServer("http://serverIP Smiley Tongue

ort/iw-cc/RFCServlet", parameters, true);

The servlet is executing fine and we have written doGet() method servlet like follow.
PrintWriter out= response.getWriter();
out.print("update DCT ");
response.setContentType("text/html");
response.getWriter().write("update DCT!");

but we cannot able to update the DCT text value with servlet return data.

could you please tell that what script we need to write in order to update my DCT values in Datacapture.cfg.

Shall we need to write any Ajax, jquery to update the DCT text fields ?

Regards,
Nageswar

Where is your callback method to handle the callserver?

Rick Poulin

Callserver merely loads your servlet in a hidden frame. It doesn't execute any callback functions on its own. Try changing your write() call to this:
[PHP]
response.getWriter().write("<html><head><title>blah</title></head><body><script type='text/javascript'>opener.top.getScriptFrame().IWDatacapture.getItem('/hello/world').setText('kablamo');</script></body></html>");
[/PHP]
When you get a handle on what's happening, dispatch the response to a JSP instead so whoever has to maintain this code doesn't jump off a bridge.

Also, don't forget to flush+close the outputstream on your Writer.

Thank you Rick, It is working fine with this approach.

And we have used another approach like Jquery instead of callServer for invoking servlet and getting back the response.

$.ajax({
url : "http://serverIP Smiley Tongue

ort/iw-cc/HritRFCServlet",
type : "get",
dataType : "text",
data &colon; { test : "test" },
error : function() {
alert(1);
},
success : function(data) {
var myStringArray = data.split(':');

IWDatacapture.getItem("/Admin/CustName").setValue(myStringArray[0]); }

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">
</script>
<script>
$(document).ready(function(){
alert("Start");
$.ajax({

url : "http://serverIP Smiley Tongue

ort/iw-cc/HritRFCServlet",
type : "get",
dataType : "text",
data &colon; { test : "test" },
error : function() {
alert(1);
},
success : function(data) {
var myStringArray = data.split(':');

IWDatacapture.getItem("/Admin/CustName").setValue(myStringArray[0]); }
});
alert("End");
});
</script>

Thanks once again.
