Commons fileupload exception

when i use commons fileupload to do file uploading, i got an exception
"javax.servlet.ServletException: Servlet execution threw an exception
fileters.ExampleFilter.doFilter(ExampleFilter.java:101)"
root cause:
"java.lang.NoClassDefFoundError: org/apache/commons/io/output/DeferredFileOutputStream
anyone can tell me:
What does it mean and how can i solve this problem?
Shall I import commons io jar to implement file uploading?
Thanks

I am having the this exception though I have placed both the jars in web-Inf/lib(commons-io-1.1.jar AND commons-fileupload-1.1.jar
any thoughts where it mightbe going wrong.
Do I need to update any other jar files as well.

Make sure that the servlet has permissions to write to that directory. I've hit that snag before, and on linux I set the permissions to nobody nobody 775.
Good luck,

Attachements with apache commons fileupload

I'm using:
http://commons.apache.org/fileupload/
to write file on server side (Tomcat running on Windows with XP or 2003).
I'm sending data to servlet with doPost() as follows:
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            DiskFileItemFactory factory = new DiskFileItemFactory();
            factory.setSizeThreshold(4096);
            factory.setRepository(new File("test"));
            ServletFileUpload upload = new ServletFileUpload(factory);
            upload.setSizeMax(1000000);
            List fileItems = upload.parseRequest(request);
            Iterator i = fileItems.iterator();
            String comment = ((FileItem) i.next()).getString();
            FileItem fi = (FileItem) i.next();
            String fileName = fi.getName();
            // db
            fi.write(new File("C:/", fileName));
        } catch (Exception ex) {
            out.print(ex.getMessage());
        out.close();
    }but it's response is:

java.lang.ClassNotFoundException: org.apache.commons.io.output.DeferredFileOutputStreamThe mentioned class is missing in the runtime classpath.
Add it (in this specific case, the JAR file with the mentioned class) to the classpath and the problem will disappear.
This class is part of Commons IO. Read the dependencies page at FileUpload user guide which JAR's you all need.

Commons-fileupload

I have a strange situation where the components on a form are dynamically built and the form is submitted to an action method "create" on a Controller class. Basically the form looks like this:
HtmlPanelGrid
(ROW 1)
--HtmlOutputText
--HtmlPanelGrid
----HtmlSelectOneRadio
----HtmlInputFileUpload
(ROW 2)
--HtmlOutputText
--HtmlPanelGrid
----HtmlSelectOneRadio
----HtmlInputText
Once form is submitted from the "create" method on the Controller class I can lookup the values of the HtmlInputText by doing:
String txtBoxValue = request.getParameter(htmlInputText.getId()); However, I cannot figure out how to access the file that was submitted (the HtmlInputFileUpload). I tried using commons-fileupload as below:
public InputStream getFileFromRequest(String fieldName, HttpServletRequest request)
     FileItemFactory factory = new DiskFileItemFactory();
     ServletFileUpload upload = new ServletFileUpload(factory);
     InputStream uploadedStream = null;
     List items;
     try
          // Parse the request
          items = upload.parseRequest(request);
          System.out.println("items.size() "+items.size());
     catch(FileUploadException fue)
          System.out.println("Exception trying to parse request for FileItems");
          System.out.println(fue);
          throw new RuntimeException(fue);
     //walk through items in the form
     ....but the items.size() is always zero. I am thinking JSF is intercepting this form before I pass it to the "parse" method and somehow this makes the form un-parsable" for commons-fileupload. If this is true...how can I get the file that was submitted before JSF messes with it...or better yet, how can I get the file that was submitted directly from JSF?

If I can't figure this one out soon...I will be forced to switch to scriptlets. Just to recap
Basically I have all these input type="file" form elements on a page that are created dynamically through a backing bean when a page loads. I can't create <t:inputFileUpload> tags and map each of them to a bean since they are dynamically created. So...I have tried to use commons-fileupload in the action method of my controller class (where the page submits) but it looks like by the time the action method is reached the MyfacesExtensionsFilter is messing up the request (because the commons-fileupload can't find any form elements when it parses the request).
Does anyone else have any suggestions or know how to get the file that was submitted from JSF? I know it has access to it because if I try and upload a file too large it throws an error message (see previous post for error message).

Commons-fileupload.jar is already in the web-inf/lib.
Is there another solution?Add the jar to the server's shared/lib or common/lib. Did you really need to ask this on an old thread?

Commons.fileupload not working

i want to upolad file with commons.fileupload lib
it doesnt get the file name
it doesnt even get through the iteration ?
if (ServletFileUpload.isMultipartContent(request)){
ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List items = servletFileUpload.parseRequest(request);

did you turn your form into a multipart form?

Apache Jakarta Commons FileUpload misleading message

I have a JSP page doing file upload using commons FileUpload package. The code looks like this:
<%
DiskFileUpload upload = new DiskFileUpload();
List items = upload.parseRequest(request);
Iterator itr = items.iterator();
while(itr.hasNext()) {
     FileItem item = (FileItem) itr.next();
     // check if the current item is a form field or an uploaded file
     if(item.isFormField()) {
          String fieldName = item.getFieldName();
          if(fieldName.equals("name"))
               request.setAttribute("msg", "Thank You: " + item.getString());
     } else {
          File fullFile = new File(item.getName());
          File savedFile = new File("c:\\tmp\\",     fullFile.getName());
          item.write(savedFile);
%>
The JSP successfully uploaded the files but it still show me HTTP Status 404 - c:\tmp (Access is denied).
What's wrong with my code? Thank you.

I just found out that the problem that I have mentioned in my previous post has nothing to do with Jakarta Commons Fileupload. It happens whenever I try throwing an exception. And it happens only when I use Internet Explorer

File size with Jakarta Commons FileUpload

Hello fella experts,
I am using the org.apache.commons.FileUpload package to upload a file via a servlet.
I'm implementing the DiskFileUpload() method in the servlet.
My problem is that I want to apply a file-size validation and specify that files with size greater than 1MB should not be uploaded.
How to accomplish this ?
Any suggessions ?
Thanx in advance.

Hi, I'm trying this code, and it works pretty fine, but when I try to transfer a .zip file, it give me a .zip file that I can't extract.
Please.. Am I doing something wrong, do I miss something??
I set already the File Type to binary...
any comments..

Jakarta Commons FileUpload ; Internet Explorer Problem

Hi all,
Environment:
Tomcat 5 ;Apache 2; JDK 1.5.0; Jakarta Commons Fileupload 1.0
OS: Windoze XP
Previously I've used jakarta commons fileupload package to succussfully to upload a file.
However, I am trying to check the content type of the file and throw an exception if its not a jpeg file. The following code works great when I use firefox. But it fails when I use Internet Explorer!
When I supply an existing jpg file on my desktop as the input to the HTML form, the code works fine. However if I enter a non-existing jpg filename, I get a "HTTP 500 Internal Server Error"! I expect to get the "Wrong content type!" message (which my JSP throws as an exception and should be caught by the error page). This problem happens only with Internet Explorer. With firefox, I get the "Wrong Content Type" message as expected.
What could be the problem? Please advise.
Thanks
Joe.

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>simple form page</title>
    </head>
    <body>
        <form method="POST" enctype="multipart/form-data" action="SimpleResponseServlet">
            <br><input type=file name=upfile></input></br>
            <br><input type=text name=note></input></br>
            <br><input type=submit value=Press></input></br>
         </form>
     </body>
</html>This is code from SimpleResponseServlet:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
   response.setContentType("text/plain;");
   PrintWriter out = response.getWriter();
   boolean isMultipart = ServletFileUpload.isMultipartContent(request);
   System.err.println(isMultipart);
   try{
            FileItemFactory factory = new DiskFileItemFactory();
            ServletFileUpload upload = new ServletFileUpload(factory);
            List items = upload.parseRequest(request);
         Iterator iter = items.iterator();
            while(iter.hasNext())
                 FileItem item = (FileItem) iter.next();
                 System.out.println(item.getContentType());
                 System.out.println(item.getFieldName());
                 System.out.println(item.getName());
                 System.out.println(item.isFormField());
       out.println("ok");
catch(Exception ex){
   System.out.println(ex.toString());
finally{
    out.close();
        this is what Tomcat 6.0 console show using https to call servlet:
false
org.apache.commons.fileupload.FileUploadBase$InvalidContentTypeException:the request doesn't contain a multipart/form-data or multipart/mixed-stream, content type header is null.if i use normal http servlet works fine.
Help me, please.
Thank you,
David.

I have replaced in html page this attribute:
action="SimpleResponseServlet"with this:
action="https://localhost:8443/ProvaImageReaderServlet/SimpleResponseServlet"and servlet can read items because there's not redirecting.
But is it a clear way call directly servlet with https???
Thank you....

Apache commons fileUpload parseRequest finds no form fields-portalComponent

Hello All,
What am I trying?
Developing a portal component (no JSP, no HTMLB).
Have used Apache commons fileUpload libraries.
What is the problem?
parseRequest method works fine when I right click and preview from PCD.
parseRequest method returns 0 html form elements when the portal component is tested under the TLN (via role -> workset -> iview)
What else did I try?
1.
I looked in to Apache documentation - there are two different APIs for two different scenarios, Servlets and Portlets.
My understanding is that I can not use portlets scenario in SAP Portal.
Servlets scenario was what worked while doing a preview from PCD.
2. I have looked into other solutions like using web dynpro and HTMLB to do file upload - not really a fan of either for various reasons.
Can any one help?
I am trying to understand why the HTTPServletRequest when parsed returns 0 form elements in the SAP Portal scenario.
Thanks!

Hello Ankur,
You said:
The reason for this is, unlike the request parameters, the multipart formdata is 'read-once-only' (because once
the data is read off the ServletInputStream, it is gone! It cannot be read again). When you call a full portal request it goes through lot of gets before reaching your component.
The above concept is not fully clear to me. I got a hint to something like this happening from this link that explains the need for portlets API scenario compared to a servlets scenario - Link: http://commons.apache.org/fileupload/using.html
(Search for Servlets and Portlets within that link)
I initially thought something like what you had replied would have happened. However, when I do a getContentLength on HTTPServletRequest in the SAP Portal mode (role -> workset -> iview), the size still includes that of the uploaded document. So like you said "it is gone! It cannot be read again" may not be accurate.
My question still remains open.

Apache commons FileUpload: Pass stream as attribute

I'm trying to implement a Filter that will change all the HTTP parameters to attributs, so that I can handle them in a consistent way throughout my servlets. The apache commons fileupload part is giving me problems. I'm changing the parameters to attributes like this
if(URLENCODED.equalsIgnoreCase(contentType) || contentType == null) // Used with normal form data
Enumeration<String> params = request.getParameterNames();
while(params.hasMoreElements())
    String name = params.nextElement();
    String value = request.getParameter(name);
    request.setAttribute(name, value);
else if(contentType.toLowerCase().startsWith(MULTIPART))     // Used when file is uploaded with POST
// Create file upload handler
ServletFileUpload upload = new ServletFileUpload();
FileItemIterator iter;
iter = upload.getItemIterator((HttpServletRequest) request);
while(iter.hasNext())
    FileItemStream item = (FileItemStream)iter.next();
    InputStream itemStream = item.openStream();
    if(item.isFormField())          // form item
      BufferedReader rd = new BufferedReader(new InputStreamReader(itemStream));
      String line;
      while((line = rd.readLine()) != null)
        streamParamsToAttributes(line)
else          // file
    request.setAttribute("filestream", itemStream);
}In my servlet I use the file stream with following code
InputStream itemStream = (InputStream)(request.getAttribute("filestream"));
useStream(itemStream)Here the useStream() method will throw a FileItemStream.ItemSkippedException since I'm trying to read data from the stream after the iter.next() was called.
So my question is, how to handle this kind of situation? The file can be quite big, so reading it to memory is not wise. And as I read, copying the stream is not a straight-forward task.
I noticed that O'Reilly has also a library for handling file uploads, is it any better in this case?
Thanks.

I looked at the O'Reilly lib and it seems to always save the file to disk. So no streaming possibility.
One solution I can think of would be to 'manually' read the data from the request. I can get the data with request.getReader() call. The file data can be found by the boundary. Now I'm wondering whether this will solve anything. Can anyone see some caveats in this approach?

Problems with Apache Commons FileUpload

I'm completely stymied here. I've been trying to get the Apache Commons FileUpload working with a JBoss 4.2 server, and having no luck whatsoever. The servlet is listed out here:
package com.areteinc.servlets;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Iterator;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileItemFactory;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
public class Filer extends HttpServlet {
     private Logger logger = Logger.getLogger(Filer.class);
     public Filer() {
          logger.setLevel(Level.DEBUG);
     protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
          logger.debug("Serving up a GET page...");
          PrintWriter writer = resp.getWriter();
          StringBuffer response = new StringBuffer();
          response.append("<HTML><HEAD><TITLE>JENA File Uploader</TITLE></HEAD><BODY>");
          response.append("<FORM action=\"Filer\" method=\"POST\" enctype=\"multipart/form-data\">");
          response.append("Upload file: <input type=\"file\" name=\"file1\"/><br>");
          response.append("Upload file: <input type=\"file\" name=\"file2\"/><br>");
          response.append("<input type=submit value=\"Start upload\">");
          response.append("</BODY>");
          writer.println(response);
     protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
          // First see if someone is uploading more than one file at a time...
          boolean isMultipart = ServletFileUpload.isMultipartContent(req);
          logger.debug("Received a POST request. Multipart is flagged as " + isMultipart);
          // Create a factory for disk-based file items
          FileItemFactory factory = new DiskFileItemFactory();
          // Create a new file upload handler
          ServletFileUpload upload = new ServletFileUpload(factory);
          // Parse the request
          try {
               List<FileItem> items = upload.parseRequest(req);
               Iterator itr = items.iterator();
               logger.debug("Size of upload is " + items.size() + " items.");
               while(itr.hasNext()) {
                    FileItem item = (FileItem) itr.next();
                    logger.debug("Filename is " + item.getName());
          } catch (FileUploadException e) {
               e.printStackTrace();
}When run, I hit it with a get operation, and get the form. When I put in 2 forms (in reality, all i want to do is use one, but I'm tinkering), I see nothing in items list...
Run, with 2 files selected to upload:
13:50:15,421 DEBUG [Filer] Received a POST request. Multipart is flagged as true
13:50:15,421 DEBUG [Filer] Size of upload is 0 items.
I've tried variation after variation after variation, and it jst doesn't work. I'm using commons-fileupload-1.2.1.
Help! :)

On the client side, the client's browser must support form-based upload. Most modern browsers do, but there's no guarantee. For your case,
The servlet can use the GET method parameters to decide what to do with the upload while the POST body of the request contains the file data to parse.
When the user clicks the "Upload" button, the client browser locates the local file and sends it using HTTP POST, encoded using the MIME-type multipart/form-data. When it reaches your servlet, your servlet must process the POST data in order to extract the encoded file. You can learn all about this format in RFC 1867.
Unfortunately, there is no method in the Servlet API to do this. Fortunately, there are a number of libraries available that do. Some of these assume that you will be writing the file to disk; others return the data as an InputStream.
Jason Hunter's MultipartRequest (available from [http://www.servlets.com/])
Apache Jakarta Commons Upload (package org.apache.commons.upload) "makes it easy to add robust, high-performance, file upload capability to your servlets and web applications"
*CParseRFC1867 (available from [http://www.servletcentral.com/]).
*HttpMultiPartParser by Anil Hemrajani, at the isavvix Code Exchange
*There is a multipart/form parser availailable from Anders Kristensen ([http://www-uk.hpl.hp.com/people/ak/java/] at [http://www-uk.hpl.hp.com/people/ak/java/#utils].
*JavaMail also has MIME-parsing routines (see the Purple Servlet References).
*Jun Inamori has written a class called org.apache.tomcat.request.ParseMime which is available in the Tomcat CVS tree.
*JSPSmart has a free set of JSP for doing file upload and download.
*UploadBean by JavaZoom claims to handle most of the hassle of uploading for you, including writing to disk or memory.
There's an Upload Tag in dotJ
Once you process the form-data stream into the uploaded file, you can then either write it to disk, write it to a database, or process it as an InputStream, depending on your needs. See How can I access or create a file or folder in the current directory from inside a servlet? and other questions in the Servlets:Files Topic for information on writing files from a Servlet.
Please note: that you can't access a file on the client system directly from a servlet; that would be a huge security hole. You have to ask the user for permission, and currently form-based upload is the only way to do that.
I still have doubt if all the moentioned resources are alive or not

Commons fileupload suddenly very slow

I've been using the commons fileupload for a couple of years with no problem. Suddenly though it's started to work impossibly slowly. I updated to the most recent version, but still no luck.
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
java.util.List items = upload.parseRequest(request);The third line of this code is taking about 30 seconds to run - even with only one image. Previously it was handling multiple images faultlessly.
Does anyone have any ideas?
Cheers

Hello,
Check to see how much free disk space there is. Right or control click the MacintoshHD icon on your Desktop, then click: Get Info. In the Get Info window, click the discovery triangle so it's facing down. You will see; Capacity and Available Make sure you have 10% available disk space, 15% is better. Insufficient available space, can cause performance issues, system corruption, and possible loss of data.
Check the hard disk for errors.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
