Deff,
На клиенте ЯваСкрипт на сервере Ява.

В общем у меня заработал вот такой код. Но он страшен как ночь.

var req;

		function ajaxFunction()
		{
			var url = "Upload_Servlet";
			
			if (window.XMLHttpRequest) // Non-IE browsers
			{ 
				req = new XMLHttpRequest();
				req.onreadystatechange = processStateChange;

				try 
				{
					req.open("GET", url, true);
				} 
				catch (e) 
				{
					alert(e);
				}
				req.send(null);
			} 
			else if (window.ActiveXObject) // IE Browsers
			{ 
				req = new ActiveXObject("Microsoft.XMLHTTP");
			
				if (req) 
				{
					req.onreadystatechange = processStateChange;
					req.open("GET", url, true);
					req.send();
				}
			}
		}

		function processStateChange()
		{
			/**
			 *	State	Description
			 *	0		The request is not initialized
			 *	1		The request has been set up
			 *	2		The request has been sent
			 *	3		The request is in process
			 *	4		The request is complete
			 */
			if (req.readyState == 4)
			{
				if (req.status == 200) // OK response
				{
					var xml = req.responseXML;

					// No need to iterate since there will only be one set of lines
					var isNotFinished = xml.getElementsByTagName("finished")[0];
					var myBytesRead = xml.getElementsByTagName("bytes_read")[0];
					var myContentLength = xml.getElementsByTagName("content_length")[0];
					var myPercent = xml.getElementsByTagName("percent_complete")[0];

					// Check to see if it's even started yet
					if ((isNotFinished == null) && (myPercent == null))
					{
						document.getElementById("initializing").style.visibility = "visible";

						// Sleep then call the function again
						window.setTimeout("ajaxFunction();", 100);
					}
					else 
					{
						document.getElementById("initializing").style.visibility = "hidden";
						document.getElementById("progressBarTable").style.visibility = "visible";
						document.getElementById("percentCompleteTable").style.visibility = "visible";
						document.getElementById("bytesRead").style.visibility = "visible";

						myBytesRead = myBytesRead.firstChild.data;
						myContentLength = myContentLength.firstChild.data;

						if (myPercent != null) // It's started, get the status of the upload
						{
							myPercent = myPercent.firstChild.data;
				
							document.getElementById("progressBar").style.width = myPercent + "%";
							document.getElementById("bytesRead").innerHTML = myBytesRead + " of " + 
								myContentLength + " bytes read";
							document.getElementById("percentComplete").innerHTML = myPercent + "%";
			
							// Sleep then call the function again
							window.setTimeout("ajaxFunction();", 100);
						}
						else
						{
							document.getElementById("bytesRead").style.visibility = "hidden";
							document.getElementById("progressBar").style.width = "100%";
							document.getElementById("percentComplete").innerHTML = "Done!";
						}
					}
				}
				else
				{
					alert(req.statusText);
				}
			}
		}

Но У меня еще один вопрос, как организовать обновление контейнера с контентом по окончанию загрузки? Когда я отправлял запросы к jsp страницам то делал так

$.post(
			 	"deletePoly.jsp",
			 	{ids:ch.toString()},
			   function(per){
			  $("#WRAPlist").load("listing.jsp");
				}
			  );

Но как в данном случае перезагрузить контейнер? Куда вставлять строку $("#WRAPlist").load("listing.jsp");?
