Java.io.StreamCorruptedException Load

Hi There,
I am getting java.io.StreamCorruptedException while doing applet-servlet communication.
I am closing all the streams once done.
But still during load i am seeing this exception in the logs though its not stopping the application to work its working fine but in the logs i am seeing this exceptions during load.
Any pointers would be of great help.
Tx

I am assuming that the ObjectOutputStream called flush() prior to attempting to read the file.
That having been said, the serialization specification should be portable across JVM's. Is the source identical on both machines? If a field has been added or removed or renamed, you may get errors similar to the one you are experiencing.

    OK I have two suggestions.
    1. Always create and flush the ObjectOutputStream before creating the ObjectInputStream.
    2. Always close the output before you close the input. Actually once you close the output stream both the input stream and the socket are closed anyway so you can economize on this code. In the above you have out..writeObject() followed by input.close() followed by out.close(). Change this to out.writeObject() followed by out.close(). It may be that something needed flushing and the input.close() prevented the flush from happening.

    Any pointers would be of great help.
    Thanks

    First, your singleton is not threadsafe, second because it's overly complicated. Simply eagerly initialize it.
    Third: why don't you use the Session or a request parameter to handle your data?
    Fourth: are you sure the serialized data is correctly written?

  • Problematic frame: # J java.nio.MappedByteBuffer.load()

    Helo all...
    I'm getting an error when generating a PDF using BIRT Framework in Eclipse. Nothing fancy, just compiling a simple report to pdf.

    I already tried:
    1. Run the program in another computers - it worked
    2. Reinstall Java on the computer - It did nothing
    3. I check the integrity of the disk C: - Nothing
    I already spent two days trying to fix this and I don't have any progress. I can't find a solution on the web either.
    Thanks in advance

    Thanks for the help.
    But it can not be related to BIRT because it works in every other computer that I tried so far. There is only one computer that not works properly.
    If it were BIRT's fault, it wouldn't work in any computer.
    Thanks again

  • Windows Vista "java.lang.ClassNotFoundException: loader.class" error.

    Hello,
    Whenever I try to visit websites that have a java applet I get a dialogue with the following error:

    I have tried uninstalling/reinstalling java, and also adding the -xmx and -xms parameters for java applet runtime setting in control panel with various values from 128m to 1g.
    The applet at http://www.java.com/en/download/installed.jsp?detect=jre&try=1 does work and reports "CONGRATULATIONS, you have the Latest version of Java!", "Java Runtime Version 1.6.0."
    I have been experiencing this problem ever since I installed Windows Vista Home Premium a day or two ago. Any help is appreciated.

  • Getting "java.io.StreamCorruptedException: invalid stream header"

    When creating a self made Stream (MacInputStream) and then using an ObjectInputStream over it to read Objects from a socket, I get this error:
    java.io.StreamCorruptedException: invalid stream header
         at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:764)
         at java.io.ObjectInputStream.<init>(ObjectInputStream.java:277)
         at TServidor.run(TServidor.java:32)
    Is there any special feature that the "self-made" streams have to implement to be possible to use ObjectInput streams over them :P ?
    Here is the MacInputStream.java code:
    import java.io.Closeable;
    import java.io.FilterInputStream;
    import java.io.IOException;
    import java.io.InputStream;
    import java.util.Arrays;
    import javax.crypto.Mac;
    public class MacInputStream extends FilterInputStream implements Closeable{
         private Mac mac; // algorithm
         private byte [] mmac; //message MAC
         private boolean FIRST_TIME;
         public MacInputStream(InputStream is,Mac mac) {
              super(is);
              this.mac=mac;
              FIRST_TIME=true;
    public int read() throws IOException{
              if(FIRST_TIME){
                   mmac = new byte [mac.getMacLength()];
                   super.read(mmac);
              if(super.in.available()==0){
                   FIRST_TIME=true;
                   return -1;
              int rbyte = super.in.read();
              FIRST_TIME=false;
              mac.update((byte)rbyte);
              System.out.println("available: "+super.in.available());          
              if(super.in.available()==0){
                   byte [] macres =mac.doFinal();
                   System.out.println("message MAC: "+new String(mmac));
                   System.out.println("calculated MAC: "+new String(macres));
                   if(!Arrays.equals(macres, mmac)){
                        throw new IOException("violated integrity");
              return rbyte;
    public int read(byte [] b) throws IOException{
         if(FIRST_TIME){
              mmac = new byte [mac.getMacLength()];
              super.in.read(mmac);          
         if(super.available()==0){
              FIRST_TIME=true;
              return -1;
         int rbytes = super.in.read(b);
         FIRST_TIME=false;
         mac.update(b);
         if(super.available()==0){
              byte [] macres =mac.doFinal();
              if(!Arrays.equals(macres, mmac)){
                   throw new IOException("violated integrity");
         return rbytes;
    }And here is the "main" function where the exception gets thrown:
    public void run() {
         try {
              ObjectOutputStream oos = new ObjectOutputStream(s.getOutputStream());
              Mac mac = Mac.getInstance("HmacMD5");
              Key key = KeyGenerator.getInstance("HmacMD5").generateKey();          
              oos.writeObject(key);
              oos.flush();
              mac.init(key);          
              ObjectInputStream cis = new ObjectInputStream(new MacInputStream(s.getInputStream(),mac));
             String test;
             try {
                   while (true) {
                        test = (String)cis.readObject();
                        System.out.println(ct + " : " + test);
              } catch (EOFException e) {
                   System.out.println("["+ct + "]");
              } finally {
              if (cis!=null) cis.close();
              if (oos!=null) oos.close();
         } catch (Exception e) {
             e.printStackTrace();
        }It's exactly in the line: ObjectInputStream cis = new ObjectInputStream(new MacInputStream(s.getInputStream(),mac));Any ideas?
    I'm starting to desperate :P

    (a) I still don't see where you are writing the MAC that you're reading. You're reading something, but it's all or part of the Object stream header I described above, which is why ObjectInputStream' constructor is throwing that exception.
    (b) You don't need to override read(byte[] b) when you extend FilterInputStream, but you do need to override read(byte[] b, int offset, int length), and you need to do it like this:
    public int read(byte[] buffer, int offset, int length) throws IOException
      int count = 0;
      do
        int c = read();
        if (c < 0)
            break;
        buffer[offset+count++] = (byte)c;
      } while (count < length && available() > 0);
      return count > 0 ? count : -1;
    }This way the read() method gets to see every byte that's read and to do its MAC thing or whatever it does. The above is one of only two correct uses of available() in existence: it ensures that you only block once while reading, which is the correct behaviour e.g. on a network.

  • Java.io.StreamCorruptedException: invalid stream header

    I am having a problem with sending two objects (over a socket). I have read in other posts that this could be due to trying to receive incompatible data types but my applications work fine if I send my objects synchronously rather than asynchronously.
    I will try my best to describe what my problem is as my code is very long.
    I have a server and a client application (2 apps). Multiple clients connect to the server and send their details (as an object) to the server. The server then amends the object (adds some more data) and sends it back to the clients. Both the SendObject and ReceiveObject class are threads and I have created a Listener (within the client) that activates when an object is received (asynchronous communication). The Listener method looks to see if the event is an instance of a particular class and casts is as appropriate (as per below).
    public void receivedObject(ReceivedObjectEvent e) {
         ReceiveObjectThread obj = (ReceiveObjectThread) e.getObject();
         if(obj.getObject() instanceof Player) {
              thePlayer = (Player) obj.getObject();
              theTable.setHandData(thePlayer.getHand());
         if(obj.getObject() instanceof GameData) {
              gameData = (GameData) obj.getObject();
              theTable.setPlayerList(gameData.getOpponents());
    }The objects that are passed between applications both implement Serializable.
    This all works fine synchronously object passing. However, if I try and spawn two sendObject threads within the server and the corresponding two receive threads within the client and wait for the Listener to activate (asynchronously) I get the following error:
    java.io.StreamCorruptedException: invalid stream header: 00057372
         at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:783)
         at java.io.ObjectInputStream.<init>(ObjectInputStream.java:280)
         at ReceiveObjectThread.run(ReceiveObjectThread.java:84)
    java.io.StreamCorruptedException: invalid stream header: ACED0006
         at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:783)
         at java.io.ObjectInputStream.<init>(ObjectInputStream.java:280)
         at ReceiveObjectThread.run(ReceiveObjectThread.java:84)
    I am sure that this problem is due to my limited knowledge on socket and data transfer. Therefore any help on this one will be gratefully received.

    Hello ejp, your reply is very much appreciated.
    If I explain how I have implemented my sockets you may be able to see where I wrong.
    When a player connects, the client sends the server a �player� object. The server receives the �player� object and passes the socket from which it connected (within the server) to a socket property within the �player� class. Whenever the server needs to send an object to that client (player), it sends the output stream from the socket property within that �player� object. ( player.getSocket().getOutputStream() ).
    Below is the code from the �SendObjectThread� class.
    * This class allows an object to be passed over a Socket
    * @author Harold Clements
    * @version 1.0.1 12-Jun-2007 (12-Jul-2007)
    //http://www.seasite.niu.edu/cs580java/Object_Serialization.html
    public class SendObjectThread extends Thread {
         private OutputStream out;
         private Object obj;
          * This constructor allows the user to passes the two parameters for transmitting.
          * @param out The data stream that the object is going to be sent to.
          * @param obj The object to be sent.
         public SendObjectThread(OutputStream out, Object obj) {
              this.out = out;
              this.obj = obj;
          * The main thread
         public void run() {
              try {
                   ObjectOutputStream objOut = new ObjectOutputStream(out);
                   objOut.writeObject(obj);
                   objOut.flush();
              } catch (IOException e) {
                   e.printStackTrace();
    }The client only has one socket which is defined when the client first makes a connection with the server. The �getOutputStream()� and �getInputStream()� are used for all communication from the client.
    Is this what you described in your first option?
    The funny thing about it all is if I create a new �receiveObjectTread� and wait for that to finish, then create another �receiveObjectTread� both objects in question (Player and GameData) are received correctly and the application works. I only have the problem when I set both threads off and leave it for the �ReceivedObjectEvent� listener to pick them up and cast them (as per my first post).
    Thanks again for your help,
    Harold Clements

    This is a inner class of NetCotroller class, it receive datas:

                while(isRunning) {

    1.
    I changed the code to this(when datagram was fragmented, just leave it alone,and back to "ds.receive(dp);" ):
    Is it OK?
    private class Receiver implements Runnable {
    @Override
    public void run() {
    boolean isCorrupted = false;//changed
    while(isRunning) {
    isCorrupted = false;//changed
    ObjectInputStream ois = null;
    Object o = null;
    try {
    byte[] receiveBytes = new byte[1024*5];
    dp = new DatagramPacket(receiveBytes, receiveBytes.length);
    ds.receive(dp);
    ByteArrayInputStream bais = new ByteArrayInputStream(receiveBytes);
    ois = new ObjectInputStream(bais);
    o = ois.readObject();
    } catch (IOException e) {
    isCorrupted = true;//changed
    System.out.println(o);
    System.out.println("IOException---NetController--receiver");
    // e.printStackTrace();
    } catch (ClassNotFoundException e) {
    System.out.println("ClassNotFoundException---NetController--receiver");
    if(!isCorrupted) {//changed
    System.out.println("receive ...@_@..." + Arrays.toString((Object[])o));
    ncl.receiveObj((Object[])o);
    }2.Is there a src of "Russia Block of Net"?Please send it to my e-mail ([[email protected]|mailto:[email protected]]), thank you very much!
