Hi, I have written a code to save an exe file from my server side to client's pc in C:\ drive.
But, I am getting error as like this:

type Exception report

message

descriptionThe server encountered an internal error () that prevented it from fulfilling this request.

exception

java.lang.OutOfMemoryError: Java heap space
note The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 3.1.2.2 logs.

For my code:

HTML

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ page import="java.io.*"  %> 
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <% 
String fileName=getServletContext().getRealPath("jdk-6u20-windows-i586.exe"); 

File f=new File(fileName); 

InputStream in = new FileInputStream(f); 

BufferedInputStream bin = new BufferedInputStream(in); 

DataInputStream din = new DataInputStream(bin); 
StringBuffer sb=new StringBuffer(); 
while(din.available()>0) 
    { 
    sb.append(din.readByte()); 
    } 

try {    
    PrintWriter pw = new PrintWriter(new FileOutputStream("c:/jdk-6u20-windows-i586.exe"));// save file 
    pw.println(sb.toString()); 
    pw.close(); 
} catch(IOException e) { 
   e.getMessage(); 
} 
          
in.close(); 
bin.close(); 
din.close(); 
%> 
    </body>
</html>

Please help me to solve this problem. And if I want to add a progress bar to display count % for downloading file than what I have to do for this in my code. Can you help me brother?

Solution 1

No Popular browser will give you access to Client's local file system
In this case you can provide a link to file by putting it in your project folder or GlassFish Server folder
or else you case use a signed applet
