I have a portlet that performs a file-upload that uses ajax. The form is in a jsp page and the action executes a servlet and the form also executes a javascript function onsubmit()

function startStatusCheck() {
    		$('submitButton').disabled = true;
    		updater = new Ajax.PeriodicalUpdater('status', '/Profile/Upload', {asynchronous:true, frequency:1, method: 'get', parameters: 'c=status', onFailure: reportError});
    		return true;
  		}

function reportError(request) {
    		$('submitButton').disabled = false;
    		$('status').innerHTML = '<div class="error"><b>Error communicating with server. Please try again.</b></div>';
  		}

My servlet uploads the file correctly but I need to execute the killUpdate() function in order to stop the update listener, though I don't know how to do it. The example code that I obtained has the function being called like below but this won't work within the portal. Here is a snippet of my servlet that tries to call the javascript function

Any suggestions?

Thanks.
