Having problem in exporting data while using "Display Tag" from sourceforge.net

Hi I am trying to use display tag in my JSP file. The tag shows the data perfectly fine. But when I click on the export options to export the data in excel or pdf it opens the appropriate application but no data is transferred. I have also included the filter in my web.xml file but still it is not working.

specify the header field Content-Length.
Sometimes Internet Explorer makes the query to your URL twice, take any actions if you depend on that.

Your servlet that returns data should look like:

ServletContext ctx = this.getServletContext();
mime = ctx.getMimeType(fileName);
aResponse.setContentType(mime);
OutputStream out = aResponse.getOutputStream();
aResponse.setContentLength( (int)lengthOfFile );
aResponse.setHeader("Pragma", "no-cache"); //HTTP 1.0
aResponse.setDateHeader("Expires", 1); //prevents caching at the proxy server
aResponse.setHeader("Cache-Control", "max-age=0");

//WRITE DATA
out.write(buf,0,bytes);
....

out.flush();
