Is it possible to get the handle of a HTML UI element in JSPDynpage?

Question

Hi Experts,
I am new to Portal Development and my current requirement is as follows:
User is provided an option to upload a file to KM from the JSP for which i used a HTMLB fileupload UI element. I was able to upload the file to the KM.
But the client wanted their specific theme for the Upload UI element to be set. The default Browse button was to be replaced by the custom image. We tried using CSS for setting the image as the background image, but failed doing it. We used the following code for achieving:
JSP Dynpage:
<hbj:fileUpload  id="docupload"                   
        maxLength="125000"                   
        size="50"   />
JQuery:
var funcName = htmlb_formid+"_getHtmlbElementId";
func = window[funcName];
var HTMLBElementIdSubmit = eval(func("<UI ID>"));
$("#"+HTMLBElementIdSubmit.id).removeClass("urUpld ");
$("#"+HTMLBElementIdSubmit.id).addClass("<custom class>");
We tried using standard file UI in HTML and we are successful in setting the background image as per the clients requirement using JQuery to replace the standard look using:
$("[type='file']").removeClass("urUpld");
    $("[type='file']").addClass("btngrey");
But we are now facing the problem in the controller where the following line is throwing an error as we are unable to get the handle for a standard HTML UI element.
com.sapportals.htmlb.FileUpload.FileUpload imageupload = (FileUpload) getComponentByName("<ID>");
Kindly let me know more if either of the 2 points below:
1. Is there an option to customize the standard HTMLB fileupload UI element as per our choice using Javascript / JQuery?
2. Is there a way to get the handle in Dynpage controller for HTML UI elements?

Hi Poojith
Not sure if this would solve your requirment but just in case might be helpful:
1. We can mix up the HTML and HTMLB components in the JSP Page. However, can access only the HTMLB components in the controller. The following link refers to what customizations are offered by the HTMLB framework:

2. Another option would be to use AbstractPortalComponents or a simple web app if that's feasible. (where custom UI themes, css and layout are more in control of the developers.)
Thanks
