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;

     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

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)

            ServletFileUpload upload = new ServletFileUpload(factory);
            upload.setSizeMax(1000000);
            List fileItems = upload.parseRequest(request);

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.

Problems with Apache Commons Validator

Hello there,
I got a quiet big problem using the a.m. validation framework. When defining a validation rule for a property like this:
<formset>
<form name="testForm">
<field property="firstName" depends="isEmail">
<arg0 key="testForm.firstname"/>
</field>
</form>
</formset>
and instanciating my validator as follows:
Validator validator = new Validator(resources, "testForm");
validator.setParameter(Validator.BEAN_PARAM, name);
everything works fine! I get a correct ValidatorResult object with a correct validation value.
But as soons as I define a second Validation on the same property like this:
<formset>
<form name="testForm">
<field property="firstName" depends="isEmail,isBlankOrNull">
<arg0 key="testForm.firstname"/>
</field>
</form>
</formset>
Nothing works anymore. When iterating over the ValidatorResults object I only get one ValidatorResult object for "isEmail" with a wrong validation value. There should be two working ValidatorResult objects for "isEmail" and "isBlankOrNull"?!?!
Are two validation method in the depends-Attribute not allowed (although it is defined in the standard)?
You can assume, that the used validator class is conform to the given org.apache.commons.TestValidator!
For any help, thx in advance!

Hey Aaron,
Could you post your code for your <field>...</field>?
Here is an example from: http://www.jsn-server3.com/struts-documentation/userGuide/dev_validator.html
<field
    property="firstName" indexedListProperty="dependents"
    depends="requiredif">
<arg0 key="dependentlistForm.firstName.label"/>
<var>
    <var-name>field[0]</var-name>
    <var-value>lastName</var-value>
</var>
<var>
    <var-name>field-indexed[0]</var-name>
    <var-value>true</var-value>
</var>
<var>
    <var-name>field-test[0]</var-name>
    <var-value>NOTNULL</var-value>
</var>
</field>
<field
    property="dob"
    indexedListProperty="dependents"
    depends="requiredif,date">
<arg0 key="dependentlistForm.dob.label"/>
<var>
    <var-name>field[0]</var-name>
    <var-value>lastName</var-value>
</var>
<var>
    <var-name>field-indexed[0]</var-name>
    <var-value>true</var-value>
</var>
<var>
    <var-name>field-test[0]</var-name>
    <var-value>NOTNULL</var-value>
</var>
</field>
<field
    property="coverageType"
    indexedListProperty="dependents"
    depends="requiredif">
<arg0 key="dependentlistForm.coverageType.label"/>
<var>
    <var-name>field[0]</var-name>
    <var-value>lastName</var-value>
</var>
<var>
    <var-name>field-indexed[0]</var-name>
    <var-value>true</var-value>
</var>
<var>
    <var-name>field-test[0]</var-name>
    <var-value>NOTNULL</var-value>
</var>
<var>
    <var-name>field[1]</var-name>
    <var-value>insureDependents</var-value>
</var>
<var>
    <var-name>field-test[1]</var-name>
    <var-value>EQUAL</var-value>
</var>
<var>
    <var-name>field-value[1]</var-name>
    <var-value>true</var-value>
</var>
<var>
    <var-name>field-join</var-name>
    <var-value>AND</var-value>
</var>
</field>
</form>" Which is read as follows: The firstName field is only required if the lastName field is non-null. Since field-indexed is true, it means that lastName must be a property of the same indexed field as firstName. Same thing for dob, except that we validate for date if not blank.
The coverageType is only required if the lastName for the same indexed bean is not null, and also if the non-indexed field insureDependents is true.
You can have an arbitrary number of fields by using the [n] syntax, the only restriction is that they must all be AND or OR, you can't mix. "
Hope that helps,
Nate

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?

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??

any comments..

//ftp.enterLocalPassiveMode();
ftp.changeWorkingDirectory(origen);
int reply = ftp.getReplyCode();
if(!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
FTPFile[] files = ftp.listFiles();
FTPFile ftpfile = null;
OutputStream output = null;
for (int i = 0; i < files.length; i++) {

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.

I have copied all the commons jars into both tomcat and my WEB-INF/lib directory. I am running the application on tomcat through Eclipse. Would this cause any problems?
Many thanks...

Diablo,
I did already have the jar, but it was an older version. I downloaded the newer version and it worked fine.
Thanks for making me look again at something I had discounted!

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.

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?

File upload using apache Commons FileUpload problem

Hi All,
I have used Commons FileUpload for uploading files from windows to unix machine. I'm able to upload files but I have a problem about the contents of file copied in unix. When i upload files few files containing special characters are not copied correctly in unix instead ascii codes are getting copied/written. Seems to be a problem with character encoding.
For example symbol "�" is not getting copied correctly in unix. So as new line character to. If anyone has faced such issues kindly provide few pointers on this. Appreciate your guidance.
Thanks,
-Aj

Thanks for the reply.
I'm using the Commons FileUpload class "FileItem" which holds the filestream data and using function
code snippet of file upload
ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List fileItemsList = servletFileUpload.parseRequest(request);
Iterator it = fileItemsList.iterator();
while (it.hasNext())
     FileItem fileItemTemp = (FileItem)it.next();
     File saveToFile = new File("newFile");
      fileItem.write(saveToFile ); // write fileItem data to saveToFile.
} FileItem object takes care of writing data to disk.No idea,how it does internally.
Thanks,
-Aj.

Problem with Apache reverse proxy after applying SP13 NW

Hello,
we have a NW04 EP Portal and a Apache reverse proxy in the DMZ. After applying SP 13 for the portal we get the following error from the reverse proxy:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /irj/.
Reason: Error reading from remote server
Apache/2.0.52 (Win32) mod_ssl/2.0.52 OpenSSL/0.9.7e Server at servername.company.de Port 443
Is is it possible, that there is a problem with sp13?
Best regards
Daniel Holstein

How to do a file upload & download using Apache Commons FileUpload?

Hi, I have read through the user guide but I don't understand what are the steps as to implementing the functions...
http://commons.apache.org/fileupload/using.html
How do I Create a servlet to read the contents(filename) of te dir where the files are, then create a collection (ArrayList for instance) with the files path and send this collection back to a jsp page.In jsp page, iterate through the collection and build the links (with scriptlets or c tags)
Can help? Thanks for the guidance!

This is my single_upload_page.jsp
<%@ page import="java.io.*" %>
<%
     //to get the content type information from JSP Request Header
     String contentType = request.getContentType();
     //here we are checking the content type is not equal to Null and
//as well as the passed data from mulitpart/form-data is greater than or
//equal to 0
     if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0)) {
          DataInputStream in = new DataInputStream(request.getInputStream());
          //we are taking the length of Content type data
          int formDataLength = request.getContentLength();
          byte dataBytes[] = new byte[formDataLength];
          int byteRead = 0;
          int totalBytesRead = 0;
          //this loop converting the uploaded file into byte code
          while (totalBytesRead < formDataLength) {
               byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
               totalBytesRead += byteRead;
          String file = new String(dataBytes);
          //for saving the file name
          String saveFile = file.substring(file.indexOf("filename=\"") + 10);
          saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
          saveFile = saveFile.substring(saveFile.lastIndexOf("\\")+ 1,saveFile.indexOf("\""));
          int lastIndex = contentType.lastIndexOf("=");
          String boundary = contentType.substring(lastIndex + 1,contentType.length());
          int pos;
          //extracting the index of file
          pos = file.indexOf("filename=\"");
          pos = file.indexOf("\n", pos) + 1;
          pos = file.indexOf("\n", pos) + 1;
