MultipartRequest File Upload

Archanazzar · June 8th, 2003, 05:54 PM

I'm trying for ages to get a working fileupload system with a variable name. I've searched the entire web for a nice (not too difficult) example but there doesn't seems to be one. I've been trying to get a working one and im this far atm. I thought that it should work but i keep getting a weird error. Weird, coz to me its standing there correct. Could anyone tell me what is wrong in this code or supply me with another 'working' version of a fileupload that's understandable for an amateur JSP programmer.

The error i get is this:
Error creating file: java.io.IOException: Posted content type isn't multipart/form-data

Here's my code:

<%@ page language="java" contentType="text/html" import = "java.io.*" import = 'com.oreilly.servlet.*' %>
<%@ page import="com.oreilly.servlet.MultipartRequest" %>
<%@ page import="java.util.*" %>
<html>
<head>
<title>Project Gosu</title>
<%
    String urlred = "loginfailure.htm";
    String name = (String) session.getAttribute( "Sessie" );
    if( name != null )
    {
        out.println( "Hello "+name+"!" );
    }
    if(name == null)
    {
        response.sendRedirect(urlred);
    }
    try
    {
        MultipartRequest mrequest = new MultipartRequest(request, "C:/jakarta-tomcat-3.2.4/webapps/ProjectGosu/Login/Replays");
        Enumeration files = mrequest.getFileNames();

        while(files.hasMoreElements() )
          {
            String upload = (String)files.nextElement();
             String filename = mrequest.getFilesystemName(upload);
            System.out.println(filename);
        }
    }
    catch(Exception ex)
    {
    System.out.println("Error creating file: " + ex );
    }
%>
</head>

if you now perl cgi then you need a small code to do it .
# !/usr/bin/perl
upload_dir =".";

$query = new CGI;

$filename = $query->param("filename");
$upload_filehandle = $query->upload("filename");
$filename =~ s/.*[\/\\](.*)/$1/;

open UPLOADFILE, ">$upload_dir/$filename";

while ( <$upload_filehandle> )
{
print UPLOADFILE;
}

close UPLOADFILE;

#this will help you to save the file by $filename
#in the present directory as I have given dot as the
#upload directory the html file will include the form
#tag and the input type=file name=filename and this will
#will give u the desired output
