Yes, i suppossed that..!! (there's a plugin named ajaxify).

The problem was that in the example are missing the xml tags.

You have out.println(“” + report + “”); and must to be out.println(“” + report + “”);

Can you help me with the “callback fuction parameter”, instead of XML I wanted it in HTML, I have the next code:

JSP (Only the .post function)
—————————————
$.post(“CostoProdPorCuentaServlet”,
{
method:$metodo,
cuenta:$accountant,
nivel:$level
},
function(data) {
$(“#datos1″).html(report.text());
},
“html”);
—————————————

On the servlet, i've changed the response.setContentType(“text/xml”); to response.setContentType(“text/html”); I think that the problem is in the way that i am catching the value in the callbackfuction.

Thanks.. !!

Hi Jorkua,

If I understood your question correctly, there's no plugin called 'ajaxify' – its the package name for my Java classes.

And as you said you are getting the response from the Servlet and make sure that you have a HTML DIV with an id as 'weatherReport', if you are following the naming conventions as given in the above example. Because JQuery looks for this ID name for updating the server's response.

do let me know if u have any more question. I'm happy to answer those.

What is the importance to use the ajaxify plugin (ajaxify.WeatherServlet). ???

Actually, I can´t get the response in the web browser, via firebug I know that servlet is returning the hoped data, but it doesn't appear on the web browser.

off course, JQuery can be implemented with all the above you said and the implementation method is same as what I explained in this post. In fact, JSF comes with pre-built JQuery support in it. So, in JSF alone, the usage will be little different.

I have tried this sample code .but when clicking the button the jsp page is not getting submitted.
I have put alerts to debug, so alerts are invoked just before post line : i.e
$.post(“WeatherServlet”, {cityName:$cityName}, function(xml) {

Please tell me why the jsp is not getting submitted.
Waiting for your reply….
