Problem with commons.fileupload

I'm using Tomcat 4.1 and before I couldn't get the compiler to find the package until I put it in my %JAVA-HOME%\jre\lib\ext folder. After I did that I could compile just fine. Now when I try uploading a file I get 'NoClassDefFoundError'. I read that this is because I have the jar file in both the %JAVA-HOME% and WEB-INF\lib . I tried running it without having it in %JAVA-HOME% and it made no difference. If anyone can help I would really appreciate it. Thanks.

I suggest taking a look at the user guide, they do some things differently than you do:

Problem with Commons FileUpload and ssl

Hi,
i want to send to servlet mulipart form data using ssl:
this is my html page:
<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....

Problem with commons-fileupload library.

Hello,
I'm using the following code to try and upload files to my Tomcat server from HTTP clients. The code is inside a JSP page. When I submit the form to this jsp page, I get no errors but the file is not being uploaded and the only out.println statement that is printing is the first one that tests if the form is multi-part. It prints true.
     boolean isMultipart = FileUpload.isMultipartContent(request);
     out.println("" + isMultipart);
     if (isMultipart) {
          DiskFileUpload upload = new DiskFileUpload();
          upload.setSizeThreshold(2000000);
          upload.setSizeMax(5000000);
          int sizeThresh = 2000000, sizeMax = 5000000;
          String dir = "c:/temp";
          List items = upload.parseRequest(request, sizeThresh, sizeMax, dir);
          Iterator iter = items.iterator();
          while (iter.hasNext()) {
               FileItem item = (FileItem) iter.next();
               out.println(item.getFieldName());
               if (item.isFormField()) {
                    continue;
               else {
                    String fieldName = item.getFieldName();
                    String fileName = item.getName();
                    String contentType = item.getContentType();
                    boolean isInMemory = item.isInMemory();
                    long sizeInBytes = item.getSize();
                    out.println("Info: " + sizeInBytes + " " + contentType + " " + fileName + " " + fieldName);
                    File uploadedFile = new File("test.txt");
                    item.write(uploadedFile);
     } Any idea what my problem is?
Thanks.

Sorry to keep posting but this gets more complex. Here's the deal.
The UploadBean works on both Tomcat 4 and Tomcat 5 as long as the code below has not been called yet for the user's session. It is code that asks the browser for authentication. Once this code has been called for the current session, the Upload Bean no longer works.
Any idea what would cause this?

J2ee.jar causes problems with commons-logging.jar

Hi All -
(JDK 1.5.0_03, commons-logging 1.0.4, latest j2ee.jar, Eclipse 3.1.0 RC3 )
I am developing some components that are to be used within j2ee containers and in standalone mode as well. When I run the software under Tomcat, it works correctly (Tomcat is not using the j2ee.jar that comes with Sun's App server obviously), but when I develop with the j2ee.jar file that comes with Sun's App server, I can't use commons-logging. For example, the code supplied below (a class with only this line in the main method, not using any j2ee features) will fail JUST by having j2ee.jar in my path, but if I take it out of the path, it works fine. I am also on the commons-logging mail list and no one there has been able to solve this issue for me. Again, if I deploy my application to Tomcat, I don't have this problem.
The isolated line that is giving me the issue (and will give the issue even in a non j2ee application that just has this one line) is this:
log= LogFactory.getLog(CommonsLoggingTest.class);
When I run this without j2ee.jar in the path, it works fine. When I run it with j2ee.jar in the path, I get this:
Exception in thread "main" org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException (Caused by java.lang.NullPointerException) (Caused by org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException (Caused by java.lang.NullPointerException))

Anyone have any ideas? Its really annoying to have to take this jar file out of my path every time I want to run a test. I could just start developing against other implementations of the j2ee classes I need (for example, Tomcat's jar files do not give this error) but for various reasons that is also undesirable.
Thanks!
Jason

This problem does not arise with commons-logging 1.0.3.
Any idea what is different in 1.0.4 that would introduce problems when Sun's j2ee.jar is in the path?

Problem with hx:fileupload

Hello!
I have a new problem. I'm using a hx:fileupload tag, but when I write in this input text intead of selecting the browse button I get a javascript error. I have read that is a problem only with IE, so I need to make readonly this field.
I have also read that a readonly is not easy for an input type file, I have found a solution here
http://www.codeguru.com/forum/archive/index.php/t-197501.html
but when I have tried the solution I find a new error, when I click over a submit file my hx:fileuploadis clear and a submit is not executed.
I don�t know why my file is clear.
Can someone help me again
thanks

Sorry, I have no solution for you but I do have the same problem. I have been searching every java site/forum I could found for a solution but no luck so far.
As soon as the �DiskFileUpload upload = new DiskFileUpload()� line is executed the program crash with a NoClassDefFoundError: javax/servlet/ServletInputStream. There is no problem creating a ServletInputStream object though. I would also appreciate it very much if anyone could give us any ideas on what might cause this error.

Problems with htmlb:fileUpload

Hi, I am trying to implement a JSPDynPage which uses the
fileUpload-Tag. In most cases it works fine but sometimes I can select a file but the next button click (onWork) event is not send to the server.
<hbj:form id="myForm" encodingType="multipart/form-data">
<hbj:formLayoutCell id="cf_fimport_2" align="center" valign="TOP" width="175">
<hbj:fileUpload id="upload" size="30" accept="plain/text"/>
</hbj:formLayoutCell>
and the button is defined
<hbj:formLayoutCell id="cf_fimport_5" align="right" paddingRight="7">
<hbj:button id="bpreview" text='doWork' design="STANDARD" disabled="false"
onClick="work"/>
</hbj:formLayoutCell>
The page is refreshed but no action is done.
Any idea?
Is there a bit more documentation about the fileUpload-Tag ?
Environment:
Windows XP
SAP EP6 SP4 Sneak Preview
IE 6.0
Regards
Edmund

Dear Edmund.
I've exactly the same problem.
In details:
Prerequisites:
1) there is <hbj:fileUpload ...> tag on the jsp.
2) The form is declared as <hbj:form id="....." encodingType="multipart/form-data">
3) There is defined button with handled event e.g. "onButtonClicked"
4) The user will insert any file to the tag
Behavior:
1) The request does NOT consist ANY components. ( I can see in the log )
2) The method "onButtonClicked" is NOT called.
3) Randomly - there is onInitialization() method called.
As it was mentioned by You, the older versions of portal works with the hbj:fileUpload correctly.
I will be very pleased with someone explaining the problem.
Regards Best
Marek
P.S.Very interesting fact: when <the hbj:fileUpload> is empty the request is sent properly - with all the components.

Problem with common services discovery !

hi, I have set the network discovery setting to use (arp-ospf, and cdp) . after the network discovery was finished I found out that there are 30 devices which had been discovered but in unreachable state !!!!
I start to ping all those devices and hopfully all of them had good reply times, I wonder how is it posible that a device go to unreachable state as long as I have its ping reply ??
thank you indeed

Discovery does more than simply ping devices. In order for a device to be reachable, Discovery must be able to communicate with the device via SNMP. Take a look at this document for more on how Discovery works:

            out.println("Plik nie zosta³ zapisany.");
            ex.printStackTrace();
}thank You

did you turn your form into a multipart form?

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 problem with Jdeveloper

Hi,
I tried to use commons fileupload with jdeveloper and I have put those two jar files under web-inf/lib directory. but it did not work. Anyone can help? Thanks in advance. Error code is shown below:

Are you sure you have the full JDK or just JRE?
Check the size of the jar you downloaded to make sure it downloaded complete.
Basic install instructions are here:

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:

Apache Tomcat/6.0.16don't know why.. any ideas?

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.

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..
public static void copyFiles(String server, String user, String pwd, String origen, String destino)
try {
FTPClient ftp = new FTPClient();
ftp.connect(server);
ftp.login(user,pwd);
ftp.setFileType(ftp.BINARY_FILE_TYPE);
//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++) {
ftpfile = files;
if (ftpfile.isFile()){
output = new FileOutputStream(new File(destino+ftpfile.getName()));
if (ftp.retrieveFile(ftpfile.getName(),output)){
output.close();
ftp.logout();
ftp.disconnect();
} catch (Exception e) {
e.printStackTrace();
System.out.println("Error : " + e.toString());

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.

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.

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

Now i want to solve my problem in my code...............
pleasde help me.............

First of all, please do not shout in topic titles. It is rude.
Secondly, please buy a new keyboard. Your dot key hangs all the time, it reads annoying.
Back to your problem: did you read the FAQ available at the [FileUpload homepage|http://commons.apache.org/fileupload]? There´s something stated about a misbehaviour in IE and how to fix it using Commons IO. It is namely sending the complete client´s file path instead of only the file name.
