Printing PDF in jsp in iframe contents -

i have researched several options printing pdf inside iframe , none seem working.

simple details:

i search parameters user.
i database search , use apachi fop generate pdf of results.
they directed webpage has print , cancel button.
when user clicks print button, open window displaying pdf.
a print dialog open user print pdf.
the pdf file deleted server.
the windows close

advanced details:

this needs work on ie8.
the fop integration not use xslt translations. uses stringreader of inputted fop xml formatted string
the window displaying pdf 2 jsp pages.
the first page:
- has iframe second jsp page source
- runs printpdf() function on load prints pdf in iframe
the second page:
uses java bufferedoutputstream , servletoutputstream
- will delete file after outputting
- uses out = pagecontent.pushbody();

here part of first jsp page (the run calls print function):

<body onload='printpdf()'> <table>     <tr>         <td class="content">             <%             // myfilename myfile parameter on url             string myfile = request.getparameter("myfile");             out.print("<iframe src='fc_view_letter.jsp?myfile="+ myfile + "' id='pdfframe'></iframe>");             %>         </td>     </tr> </table> <script>     function printpdf()     {         var id = 'pdfframe';         var iframe = document.frames ? document.frames[0] : document.getelementbyid(id);         var ifwin = iframe.contentwindow || iframe;          ifwin.focus();         ifwin.printpage();         //ifwin.print();     } </script> </body>

here of second jsp page (the 1 shows pdf):

<%@ page session="false" %> <%@ page import="java.io.*" %> <%@ page import="java.net.urldecoder" %> <html> <head> </head> <body> <% string myfile = request.getparameter("myfile"); string myfiledecoded = ""; myfiledecoded = urldecoder.decode(myfile, "utf8"); string myfilename = myfiledecoded; string extension; int dotpos = myfilename.lastindexof(".")+1; extension = myfilename.substring(dotpos); int slashpos = myfilename.lastindexof("/")+1; string secondparam = "filename=" + myfiledecoded.substring(slashpos); response.setcontenttype("application/pdf"); response.setheader("content-disposition", secondparam); try {         servletoutputstream sout = response.getoutputstream();         response.setheader("content-disposition", secondparam);          file  file  = new file(myfilename);         fileinputstream fstream = new fileinputstream(file);          bufferedinputstream bis = null;         bis = new bufferedinputstream(fstream);           bufferedoutputstream bos = null;         bos = new bufferedoutputstream(sout);          byte[] buff = new byte[1024];         int bytesread;          while(-1 != (bytesread = bis.read(buff, 0, buff.length))) {              bos.write(buff, 0, bytesread);         }           bis.close();          bos.close();           sout.flush();          sout.close();           //file.delete();  } catch (exception e)  {      system.out.println("exception occured...................." ); }    out.clear();     out = pagecontext.pushbody(); %> </body> </html>

what think issue: i'm thinking buffer eliminates of html , displays pdf. or @ least in ie. when looked in firefox embedded pdf file. maybe cannot grab contents of iframe because no longer html.
