response.Header() not working in JSF Portlet

[pa...@wipro.com]

Hi All,
         I have a JSF portlet where i want to save the contents of my
Text area on the click of a button to a word document.
         (IBM Websphere portal)

     <h:inputTextarea id="text1"
value="#{pc_TextAreaView.textAreaValue}" rows="10" cols="50" />
     <h:commandButton id="save" value="Save As Word"
action="#{pc_TextAreaView.SaveAsWord}"/>

In my page bean i have written the follwoing code but the
response.setHeader() doesn't seem to work.
I am not getting any pop dialog and i cannot save my file.
Please let me know what is wrong in this code snippet.How can i make it
work in my portlet.

public String SaveAsWord() {
 
  FacesContext context = FacesContext.getCurrentInstance();
  HttpServletResponse response =
(HttpServletResponse)context.getExternalContext().getResponse();
  response.setContentType("application/vnd.ms-word");
     response.setHeader("Content-Disposition", "attachment;
filename=myfile.doc");
     response.setHeader("Cache-Control", "no-cache");
     try{
     byte[] buf=new byte[4*1024];
     InputStream inStream=new
ByteArrayInputStream(textAreaValue.getBytes());
     OutputStream outStream=response.getOutputStream();
     int sizeRead;
     while ( ( sizeRead=inStream.read(buf, 0, buf.length) ) != -1 )
       {
       outStream.write(buf, 0, sizeRead);
       }
     inStream.close();
     outStream.close();
  }
     catch(IOException ex){
      ex.printStackTrace();
      }
     return null;
  }

Best Regards,
Pallavi
