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?

    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

  • 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?

    The relevant jar file, commons-digester.jar is in the the WEB-INF/lib folder, just like all the other commons-*.jar files.
    My CLASSPATH variable doesn't contain anything except a an XMLSpy jar file.
    I'm running WLS 8.1 SP2.
    Any help/hints are greatly appreciated.

    I would set "prefer-web-inf-classes" to "true" in your "weblogic.xml" file. Without this, you may be getting classloader confusion with some of the commons jars that are used within WebLogic.

  • Sun J2EE 1.4 Server domain could not start (org/apache/common/launcher/..)

    I am having problem with starting Sun J2EE Server 1.4. I had no problem with starting and stopping the server until today. I was not able to figure out what the problem is. I have tried reinstallation but did not work either. I also have reinstalled my J2SDK, but did not fix the problem. I am using J2SDK1.4.2_03 on Windows 2003 Server. Before the problem occured, I was working on a simple JMS applcation and trying to connect to J2EE server from a standalone JMS client at different machine. I am not sure what really caused the problem, but uninstalling it and reinstalling it does not change anything.
    Here is my error message when I do start-domain domain1 at asadmin mode:
    asadmin> start-domain domain1
    Starting Domain domain1, please wait.
    Log redirected to C:\Sun\AppServer\domains\domain1\logs\server.log.
    abnormal subprocess termination: Detailed Message:Error: org/apache/commons/launcher/LaunchFilter
    CLI156 Could not start the domain domain1.
    I have tried to start it by using startserv.bat at domain1 directory and also the desktop shortcut Start Default Domain. Nothing works. I'do apprecited it if you can share any ideas or suggestions regarding this issue.
    Thank you in advance.

    I made some changes to my enviroment variables and added jar files to the J2SDK <<J2SDK_HOME>>/jre/lib/ext folder in order to run the standalone JMS client.
    Here is my classpath settings:
    .;C:\Sun\AppServer\lib\j2ee.jar;
    C:\Sun\AppServer\lib\appserv-admin.jar;
    C:\Sun\AppServer\lib\appserv-rt.jar;
    C:\Sun\AppServer\lib\appserv-rt.jar;
    C:\Sun\AppServer\lib\appserv-ext.jar;
    C:\Sun\AppServer\lib\install\applications\jmsra\imq.jar;
    C:\Sun\AppServer\lib\install\applications\jmsra\imqadmin.jar;
    C:\Sun\AppServer\lib\install\applications\jmsra\imqjmsra.jar;
    C:\Sun\AppServer\lib\install\applications\jmsra\imqutil.jar;
    C:\Sun\AppServer\imq\lib\fscontext.jar;C:\J2EE\tutorial\j2eetutorial14\examples\ejb\simplemessage\SimpleMSGAppClient.jar
    I also have added appserv-rt.jar, appserv-rt.jar, appserv-ext.jar, imq.jar, imqadmin.jar, imqjmsra.jar, and imqutil.jar in the <<J2SDK_HOME>>/jre/lib/ext/ folder. I know they were redundant but just wanted to make sure. Can any of these be causing the problem?
    Again, thank you and let me know if you need any other info.

  • 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,

  • Apache commons fileupload

    Hi
    I have written fileupload servlet , and it is working fine on windows xp.If I use the same program in solaris it is not saving the file on the server.I am not getting any exception.Can anybody help?
    Thanks in advance.

    Most likely you're using relative paths in java.io stuff and thus the actual location of the saved file differs per environment. With other words, the file is actually saved, but not there where you think it is.
    Use absolute disk file system paths in java.io all the time. You should not assume that relative web paths are actually disk file system paths.
