Java.io.IOException: Corrupt form data: no leading boundary

Hi,
I am trying to upload pdf files using a servlet. The Enctype of the form which calls this servlet is multipart/formdata. I use O'Reilly upload component which uses the class MultipartRequest to do the uploading. The form has textboxes and textareas whose data is also submitted.
The problem is, when I try uploading with Greek text in these text area and textbox, I get the exception
java.io.IOException: Corrupt form data: no leading boundary: -----------------------------7d21b8c1502c0 != -----------------------------7d21c2c1502c0
Has anyone encountered this problem? Any help will be greatly appreciated.

  • How to solve java.io.IOException: Corrupt form data: premature ending

    hei evryone!
    Does anyone knows how to solve this bug?
    java.io.IOException: Corrupt form data: premature ending
    Im using Oreilly's cos.jar MultipartRequest
    here is my form :
    <FORM METHOD="POST" NAME="uploadform" action="mbbfile" ENCTYPE="multipart/form-data">
    <TR>
    <TD>Select a File:</TD>
    <TD><INPUT TYPE="FILE" NAME="srcfile" style="width:400px"/></TD>
    </TR>
    <TR><TD><INPUT TYPE="SUBMIT" VALUE="Send"/></TD></TR>

    HERE IS mbbfile which is a servlet :
    package mbb.servlet;
    import java.io.IOException;

    import javax.servlet.RequestDispatcher;
    import javax.servlet.ServletContext;
    import javax.servlet.ServletException;

              try{
              MultipartRequest multi = new MultipartRequest(req,filePath,5*1024*1024);
              }catch(Exception e){
                   System.out.println("MBBFileServlet Exception ---> "+e.getMessage());
         public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
              doGet(req,res);
    Sometimes it works meaning the file is uploaded in the directory without any exception, sometimes the file is uploaded but with exception on the log saying "MBBFileServlet Exception ---> Corrupt form data: Premature Ending". and sometimes the files is not uploaded at all and when i check the error is : "MBBFileServlet Exception ---> Corrupt form data: Premature Ending". Can anyone please help me on this matter. Thx!
    Your response would be deeply appreciated.

    Hi all!
    Since I've spent some days now trying to figure out what was wrong with my file upload in Struts 1.1, I would like to share my solution with the rest of you in order to spare you for the same amout of wasted time I've spent :-)
    My platform is Resin 3.0.8 and Struts 1.1. My problem was that JPEG's got corrupted when arriviving at the server. After a few days searching on the net, I tried with a plain servlet and the O'Reilly package, and the app worked perfect.
    Here is my servlet:
    package no.yourcompany.yourapp.servlet;

    try {
    MultipartParser parser = new MultipartParser(request, MAX_FILE_SIZE_IN_BYTES);
    while ((currentPart = parser.readNextPart()) != null) {
    if (currentPart.isFile()) {

  • MultipartRequest java.io.IOException: Corrupt form data: premature ending

    i try to upload a file using MultipartRequest

    Then whatever is uploading the file, isn't doing it correctly.

  • Java.io.IOException: Corrupt GZIP trailer

    I have some code to gunzip a byte array of data. I've used this code frequently and it works well. However, I just tried unzipping a byte[] array that is 4,529,218 bytes which expands to a file that is 2,157,763,194 bytes (on an SGI).
    I get a:
    java.io.IOException: Corrupt GZIP trailer
    thrown from the while ( ( length = zipin.read(buffer, 0, sChunk) ) != -1) line below.
    I did a quick Google search and found these links:
    http://www.aoindustries.com/docs/aocode-public/com/aoindustries/util/zip/CorrectedGZIPInputStream.html
    http://www.sanger.ac.uk/Software/Artemis/artemis_docs/uk.ac.sanger.pathogens.WorkingGZIPInputStream.html
    with comments like:
    Works around the "Corrupt GZIP trailer" problem in GZIPInputStream by catching and ignoring this exception.
    A wrapper class to work around a bug in GZIPInputStream. The read() method sometimes throws a IOException complaining about a Corrupt GZIP trailer on the jdk 1.1.8-13 on the Alphas. This wrapper catches and ignores that exception.
    The code below writes out the correct number of bytes to the filesystem, but I get the IOException. From my Google search, it appears that some people have run into this problem before. Does anyone here know if this is a bogus error, or if it is valid? Is this a known "bug" in Java?
    Note: the file size is larger than the Integer.MAX_SIZE. Is there an integer somewhere in the code that checks the trailer that was exceeded because of the file size?
    (I ommited some catch code to make reading it easier)
    private void gunzip(byte[] data, File file)
        int sChunk = 8192;
        // create input stream
        GZIPInputStream zipin;
        try
            ByteArrayInputStream in = new ByteArrayInputStream(data);
            zipin = new GZIPInputStream(in);
        catch (IOException e)
            // omitted for clarity
        byte[] buffer = new byte[sChunk];
        FileOutputStream out = null;
        // decompress the data
        try
            out = new FileOutputStream(file);
            while ( ( length = zipin.read(buffer, 0, sChunk) ) != -1) // error here
                out.write(buffer, 0, length);
        catch (IOException e)
            // omitted for clarity
        finally
            try
                out.close();
                zipin.close();
            catch(IOException e)
                // omitted for clarity
    }

    In GZIPInputStream.java:
         * Reads GZIP member trailer.
        private void readTrailer() throws IOException {
         InputStream in = this.in;
         int n = inf.getRemaining();
         if (n > 0) {
             in = new SequenceInputStream(
                   new ByteArrayInputStream(buf, len - n, n), in);
         long v = crc.getValue();
         if (readUInt(in) != v || readUInt(in) != inf.getTotalOut()) {
             throw new IOException("Corrupt GZIP trailer");
        }This line
    if (readUInt(in) != v || readUInt(in) != inf.getTotalOut())appears to be verifying the CRC value and data size from the trailer with data actually read from the stream.
    The inf.getTotalOut() returns an integer. My file size is greater than a 32 bit integer value.
    I looked at the GZip file specification at:
    http://www.faqs.org/rfcs/rfc1952.html
    and see that the trailer input size is defined as:
    ISIZE (Input SIZE)
                This contains the size of the original (uncompressed) input
                data modulo 2^32.I assume data modulo 2^32 means that this is supposed to be a 32 bit integer.

  • Java.io.IOException: data error cyclic redundantie check

    Dear all,
    I did a fresh install of JDeveloper 10.1.3.2.0 with JHeadstart 10.1.3.26 on my computer. These are the versions we use.
    I've made a database connection, so that's allright.
    When I open JDeveloper and I try to add an Application, we allready have made(with the same versions) I get the next error in JDeveloper: xxx.jws was saved in version file format and cannot be opened with an older version of JDeveloper. The version is not mentioned...
    In the terminal I get the messeage of my subject: java.io.IOException: data error cyclic redundantie check.
    I'm sure i'm using the same versions.
    Does anybody know what went wrong?
    regards,
    Marcel.

    It's like the data stream is getting messed up...so I would think of a few things:
    1) Bad memory?
    2) Bad connections?
    3) Bad disk?
    4) Viruses
    Anything that can screw up the data steam.
    Other than that....maybe as simple as reinstall the JVM and put new compiled code out there and see if it behaves.

  • Java.io.IOException: Data error (cyclic redundancy check)

    Dear everyone,
    I have a utility that copys a file, using streams.
    It has always worked fine, but I ran into an
    exception this morning:
    java.io.IOException: Data error (cyclic redundancy check)
    from the call:
    int bytes = fileInputStream.read(byteBuffer);
    Would you know what this exception is about? I
    haven't seen that exception after that, though.
    So it's a bit puzzling. Any help, or clue towards
    solving this problem is appreciated.
    Thanks a lot!
    George

    What i dont get is in the entire stack trace i am not able to locate which of my application files is causing the errors
    I searched on net and found a few root causes but i am not able to find out exactly which class file is causing the stack trace
    Any suggestions are most welcome
    Thanking in advance

    Did you do something strange like writing the object out using the Servlet response's output stream and then attempted to redirect or forward a user to another page? That is usually how the IllegalStateException gets generated. You would still see a valid response from the caller's perspective, but since you attempted to forward or redirect after data has already been written to the stream on the server, an exception is thrown there.

  • Selected data is stored in corrupted form

    Hello All,
    In ECC 6.0 unicode system, I am fetching the records from AUSP table in following 2 ways:
    a) Fetching the result in internal table of type of standard table AUSP.
         The fetched records are absolutely fine.
    b) Fetching the records in internal table of local type:
          The fetched records are in corrupt form. The CHAR fields have extra byte and some fields have arbitary characters like ####.
         The local defined type is as following:
    TYPES: BEGIN OF lt_s_ausp,
           mandt(000003) TYPE c,
           objek(000050) TYPE c,

    Would you please help me to find the reason for the issue (why data gets corruped when stored in lt_tab in case b?)? Thanks in advance...

  • Java.io.IOException: Resource not found: org/joda/time/tz/data/ZoneInfoMap

    I've been attempting to develop test classes using the PowerMock and Mockito mock frameworks
    I've developed the tests in Eclipse in windows XP (64 bit) and the tests run to completion with passes
    One of the classes being tested references the joda-time-1.4.jar and this jar contains the resource org/joda/time/tz/data/ZoneInfoMap
    I then attempted to migrate the development to running the unit tests in a Windows XP command prompt launched by Maven 2 (mvn)
    I get test errors, but the nature of the error depends where I set my JAVA_HOME
    a) if I set my JAVA_HOME to a standard Sun JDK (C:\Program Files (x86)\Java\jdk1.5.0_21), then I get the resource not found error for one test only - here is an extract from the exception:

  • Java.io.IOException:Data has already been flushed to the client

    hi,
    will u please anyone tell about this exception? its very urgent to me?
    i am getting exception when i ma forwarding a page in jsp.
    exception is :
    java.io.IOException : Data has already been flushed to the client.
    my code where i am getting this exception is:
    if(filled_var .equalsIgnoreCase("y"))
    %>
    <jsp:forward page="/editForm.jsp">
    <jsp:param name="formNum" value="<%= formNum%>"/>
    </jsp:forward>
    <%      
    here i am getting that error. please help me to find a solution in this.

    A forward can only be performed if the "response is not committed". The response is committed when:
    1) you do a forward
    2) enough data is outputted for the buffer to be flushed
    3) you flush the buffer manually (or you do an include with a flush="true" for example)
    It must be either 2 or 3 in the case of a JSP. So if you output a lot of data before the forward, make sure you try to do the forward BEFORE you output all that data.

    Your error is because you have already flushed or closed your output stream. Your response is done but you are trying to forward after the fact.

    This is an issue with my code. I was selectively serializing a class member and relying on EOFException to detect if the class member should be initialized during readExternal(). Following shows the situation:
    public class A implements ExternalizableLite{
         private A1 a1 = null; // A1 is ExternalizableLite
         private A2 a2 = null; // A2 is ExternalizableLite
         public A(){}
         public void setA1(A1 a1){ this.a1 = a1; }
         public void readExternal(DataInput in) throws IOException {
             this.a1.readExternal(in);
             this.a2 = new A2();
             try{
                 this.a2.readExternal(in);
             catch(EOFException ex){ // a2 is null
                 this.a2 = null;
        public void writeExternal(DataOutput out) throws IOException {
            this.a1.writeExternal(out);
            if(this.a2 != null) this.a2.writeExternal(out);
    }A map had the above class A as the value and when the map was getting serialized, I was getting the exception. I changed class A (as below) to always initialize a2 to a non-null but empty class and the error went away:
    public class A implements ExternalizableLite{
         private A1 a1 = null; // A1 is ExternalizableLite
         private A2 a2 = new A2();
         public A(){}
         public void setA1(A1 a1){ this.a1 = a1; }
         public void readExternal(DataInput in) throws IOException {
             this.a1.readExternal(in);
             this.a2.readExternal(in);
        public void writeExternal(DataOutput out) throws IOException {
            this.a1.writeExternal(out);
            this.a2.writeExternal(out);
    }This means needless serialization/deserialization when a2 is null but the hit is negligible. Is there a way to get around the null values?
    Thanks
