Export data from an iView to Excel, get a login screen displayed in Excel

Question

Hi
I'm trying to export data from a tableview to excel, I followed the instruction posted by Detlev Beutner, created a class extends AbstractPortalComponent, and overwrote the doOnNodeReady:
HttpServletResponse response = request.getServletResponse(true);
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition", "filename=\"text.xls\"");
I did write some test output in doContent:
         aResponse.write("Filed11,Filed12,Field13");
         aResponse.write("Field21,Field22,Field23");
I was hoping to see the excel to display the content "Field11 Field12...", but I got a portal login screen displayed in Excel.
Does anyone have the same experience and and idea on this?
Thanks
Yutong

Sure, here is the sample code for method doOnNodeReady
protected void doOnNodeReady(IPortalComponentRequest request,
      IEvent event)
  //set http content type to excel format
  HttpServletResponse response = request.getServletResponse(true);
  response.setContentType("application/vnd.ms-excel");
  response.setHeader("Content-Disposition", "attachement;filename=\"abc.xls\"");
  java.io.PrintWriter out = response.getWriter();
  // print out the header
  out.print(headerSubject + "\t");
  out.print(headerDueDate + "\t");
  // then print out your data
  out.close();
