i'm getting error while opening pdf in java code :

<%@ page language="java"     import="java.util.*,         java.io.*,          java.lang.*,          com.eb.util.propertyutil,             javax.portlet.*,          com.ub.ac.aeans.*,         com.ub.pm.wob,com.eb.ac.aservice,          javax.xml.bind.datatypeconverter,com.eb.patientchecklist.portlets.*;"     pageencoding="iso-8859-1"%><%@ taglib     uri="http://java.sun.com/portlet_2_0" prefix="portlet"%><portlet:defineobjects />     <%         response.reset();         response.setcontenttype("application/pdf");         string wobid = resourcerequest.getparameter("wobid");         string filename = resourcerequest.getparameter("filename");         string dir = propertyutil.getpropertyvalue("doc_base") + wobid                 + "/" + filename;         int count = new file(dir).list().length-1;         system.out.println("dir hi        :" + dir);         string root = dir + "/" + count + ".pdf";         file pdffile = new file(root);          response.setcontentlength((int) pdffile.length());         system.out.println("path   :" + root);         fileinputstream reader = new fileinputstream(pdffile);         int line;         outputstream responseoutputstream = response.getoutputstream();         while ((line = reader.read()) != -1) {             responseoutputstream.write(line);             system.out.print(line);         }     %>

when remove line:

response.reset();

the file called in browser it's showing me this:

ava tutorial pdf) /creator (��) /producer (��wkhtmltopdf) /creationdate (d:20130708155338-05'00') >> endobj 3 0 obj << /type /extgstate /sa true /sm 0.02 /ca 1.0 /ca 1.0 /ais false /smask /none>> endobj 4 0 obj [/pattern /devicergb] endobj 8 0 obj [0 /xyz 34.0799999 807.919999 0] endobj 9 0 obj [0 /xyz 39.8400000 636.079999 0] endobj 10 0 obj << /type /annot /subtype /link /rect [34.0799999 772.399999 283.680000 782.959999 ] /border [0 0 0] /a << /type /action /s /uri /uri (http://www.tutorialspoint.com/java/java_pdf_version.htm) >> >> endobj 12 0 obj <> endobj 13 0 obj <> endobj 11 0 obj <> endobj 14 0 obj <<

then when return line:
