Download a XML file via jsf -

-

i trying download xmls file zipped archive using richfaces. have done usual way of downloading files. have requirement download zip .xlsx files. same piece of code working zipped archive of xlsx files.

i have throwdownload() follows..

  public void throwdownload(bytearrayoutputstream baos, string filename) throws ioexception {      facescontext facescontext = facescontext.getcurrentinstance();     externalcontext externalcontext = facescontext.getexternalcontext();     httpservletresponse response = (httpservletresponse) externalcontext             .getresponse();       response.reset();     response.setcontenttype("application/zip");     response.setcontentlength( baos.size() );     response.setheader("content-disposition", "attachment; filename=\""             + filename + "\"");      bufferedoutputstream output = null;     final int buffersize = 20480;      output = new bufferedoutputstream(response.getoutputstream(),             buffersize);     output.write(baos.tobytearray());      facescontext.responsecomplete();  }

the same code works fine zip containing .xlsx files. zip containing .xml files save dialog shown browser downloaded file having 0 bytes. response headers in fiddler 2 requests follows:
