If you post enough of a snippet to try and debug the code, I will take a whack at it this afternoon.

I have a dialog contenent a div

div.innerHTML =
		[ "<table><tbody>",
		  "<tr>",
		    "<td align='center'><label for='", toId, "'>Num: <input autocomplete='on' style='width: 21em' type='text' id='", toId, "' value='", toValue, "'/>",
		    "</td>",
		  "</tr>",
		  "<tr>",
		"<td colspan='2' align='center'>",
		"<textarea rows='10' cols='100' style='width: 25em' name='testo' id='", bodyId, "'>", bodyValue, "</textarea>",
                "<br>",
		"<form name='uploadForm' id='uploadForm' method='post' enctype='multipart/form-data' action='/service/upload?fmt=raw'>",
			"<input type='file' name='attach' />",
			"<input type='hidden' name='requestId' value='firstAttach' />",
		"</form>",
		"</td>",
		"</tr>",
		"<tr></tr>",
		"</tbody></table>" ].join("");
        el.appendChild(div);

	var dialog_args = {
		title : "Zimlet",
		view  : view
	};
	var dlg = this._createDialog(dialog_args);
	dlg.popup();

On click on the OK button a function is called:

        var form = document.getElementById("uploadForm");
	var iframe = document.createElement("iframe");
	var view = new DwtComposite(this.getShell());
	view.getHtmlElement().appendChild(iframe);
		
	var post = new AjxPost(iframe);
	var callback = new AjxCallback(this, this._resultCallbackAlert);
	post.execute(callback, form);

But callback is not called and a new window is opened with the result ouput in it.

I also tried in this way, but it doesn't work

document.body.appendChild(el);

Thank's again

I notice that it's been over a year and a half now, and no one has answered Jiggy's question.
Is there some sample code somewhere that shows how to use AjxPost to post variables to another website or web service?
I have not found any sample Zimlets that use AjxPost.

This may not be a "perfect" solution. It is possible to GET data with AjxRpc.invoke, but since a regular AJAX request cannot go to other webservers (it's a browser restriction), I prefer to use a proxy jsp that receives the data from the client, passes it on to the external service, gets a result back and sends it to the client.

Something like this:

proxy.jsp:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page import="java.io.*"%>
<%@page import="java.net.*"%>
<%@page import="java.util.*"%>

<%
List<String> allowedDomains=new ArrayList<String>();
allowedDomains.add("www.zimbra.com"); // external domain you want to call, without prefix, and you may add several domains by duplicating the line

    try {
    URL url = new URL(URLDecoder.decode(request.getParameter("url")));

    if (!allowedDomains.contains(url.getHost()))
        throw new Exception("Invalid hostname");

    InputStream is = url.openStream();
    BufferedReader r = new BufferedReader(new InputStreamReader(is));
    StringBuffer buf = new StringBuffer();
    String line;
    while ((line = r.readLine()) != null) {
         buf.append(line);
    }
    r.close();
    is.close();

    out.print(buf.toString());

} catch (Exception ex) {
}
%>

Then call this in javascript:

	var url=this.getResource('proxy.jsp'); // "this" being the handler object of the zimlet
	var str=escape("http://zimbra.com"+"?"+"param1=value1&param2=value2");// Create the request string
	var reqHeader = {"Content-Type":"application/x-www-form-urlencoded"};
	AjxRpc.invoke("url="+str, url, reqHeader, new AjxCallback(this, this.callbackfunction));

This code is for GET requests, but a little tweaking might just make it POST as well. The org.apache.commons.httpclient.methods.PostMethod class is a good place to start if you must POST the data. That'll of course be used in the proxy jsp.
