how to call applet with swfupload?
===

I am new to swfupload for uploading file from client machine. My uploading program is working fine. Its look like: 

**My Upload.jsp :**

    var swfu;	
    			UploadFileOnLoad = function() {
    				var settings = {
    					flash_url : "<%=session.getAttribute("contextPath") %>/script/swfupload/swfupload.swf",
    					flash9_url : "<%=session.getAttribute("contextPath") %>/script/swfupload/swfupload_fp9.swf",
    					**upload_url: "<%=session.getAttribute("contextPath") %>/fileUpload/fileUpload.works"**,				
    					post_params: {"FILE_PRIVACY" : "filePrivacy", "FILE_KEYWORD" : "fileKeyword","FILE_DETAILS" : "fileDetails", "FILE_COMMENTS" : "fileComments", "FILE_TYPE" : "fileType", "FILE_FOLDER" : "fileFolder"},    					
    				};    	
    				swfu = new SWFUpload(settings);
    		     };

I have set a url for my UploadController at upload_url as given above. 

**My FileUploadController:**

        @RequestMapping(value = "/fileUpload.works")
        	public String uploadFile(@RequestParam("FILE_PRIVACY") String filePrivacy,
        			@RequestParam("FILE_KEYWORD") String fileKeyword,
        			@RequestParam("FILE_COMMENTS") String fileComments,
        			@RequestParam("FILE_TYPE") String fileType,
        			@RequestParam("FILE_FOLDER") String fileFolder, Model model,
        			HttpServletRequest request, HttpServletResponse response) {
        		try {    
        			MultipartHttpServletRequest m = (MultipartHttpServletRequest) request;
    //upload code goes here...
My controller get hit successfully and I can access all that data. But my question is 

1) how can I call to Applet class rather than UploadController?

2) can I write my uploadController's code as given above in Applet class? If yes, how can get all that thinks in applet which is given above controller? because I want to do some work at client side.
thanks in advance.
