InfoPath Dev

Sorry, I noticed a typo the last line of my current code should read: nodeAlias.text = System.Environment.UserName;

OK so here is the code that I have in my event: function XDocument::OnLoad(oEvent) { // Avoid DOM updates when the document has been digitally signed. if (XDocument.IsSigned) return; var now = new Date(); initializeNodeValue(''/ar:absenceRequest/ar:date'', getDateString(now)); initializeNodeValue(''/ar:absenceRequest/ar:time'', ...

So what would the code look like to use System.Environment.UserName in the on load event to get the username into a text box? I realize this is probably a stuped question but I'm new to Infopath and java.
