Stream Corruption - Servley can read object?

I get the below exception when I increase the size of an objcet that I serialise. I have an object - it contains a vector. If this vector has 10000 rows then my sevlet reads it out of a database fine (blob format inside MySQL). If I add another vector of any size to the object then i get stream corrupted. If I try to add any class attributes the again stream corrupted.
Using JDK1.4 and Tomcat3.3.2

Thanks for any help !

thanks already have done the flushing I think the error is something to dowith 64kb limits in the UTF encoding scheme. Objects headers that are greater than 64kb seem to mess up!
Have some dukes for sensible suggestions though

Cannot send and read objects through sockets

I have these 4 classes to send objects through sockets. Message and Respond classes are just for
trials. I use their objects to send ıver the network. I do not get any compile time error or runtime error but
the code just does not send the objects. I used object input and output streams to send and read objects
in server (SOTServer) and in the client (SOTC) classes. When I execevute the server and client I can see
that the clients can connect to the server but they cannot send any objects allthough I wrote them inside the main method of client class. This code stops in the run() method but I could not find out why it
does do that. Run the program by creating 4 four classes.
Message.java
Respond.java
SOTC.java
SOTServer.java
Then execute server and then one or more clients to see what is going on.
Any ideas will be appreciated
thanks.

ObjectStreams send a few bytes at construct time. The OutputStream writes a header and the InputStram reads them. The InputStream constrcutor will not return until oit reads that header. Your code is probably hanging in the InputStream constrcutor. (try and verify that by getting a thread dump)
If that is your problem, tolution is easy, construct the OutputStreams first.

Blocking reading object from stream

I have a thread that continually reads objects from the input stream, so I use the readObject() method. My problem is that it doesn't block when there is no input. it just throws exceptions and I cant find a way to check first if there's anything output from the other side of the stream so do a check. thank you!

Sorry! My mistake! I was confused!

How applet can read continuous data stream

How applet can read continuous data from server(like database update)

You can keep opened a socket to the server. You can send any data from/to the applet in that way.

//if i pass true as parameter in FileOutputStream it gives Stream Corrupted exceptionI agree. You can't append to a file written with an ObjectOutputStream. You would have to read it all in, write it all out again and write the new object. You're better off keeping the file open while you still have objects to write to it.
while ((temp = (Storingobject) objIn.readObject()) != null) {ObjectInputStream.readObject() only returns null if you wrote a null. If you're not writing nulls, the correct technique is to loop until you get an EOFException. I don't favour explicitly writing a null just to get around this as suggested above, as it means you can never write a null for any other purpose.

Server hangs up when tryin to read object Urgent Help Plz

Hi,
I've been working on a client-server model for a while, I've tested my applicaction a thousand of times locally (I mean, server and serveral clients running on the same machine) and it's ok, now I finally run server in a remote host and I find it rarely works fine, most of the times server hangs up when tryin to read objects I dont know why.
this is the part of the server-code where the problem begins:
public int EscucharSocket(){
        Socket cliente = null;
        System.out.println("Servidor en escucha...\n");
        while(true){
            try{
                cliente = SocketS.accept();
                //I get client's ip and port
                String ip = cliente.getInetAddress().getHostAddress();
                int puerto = cliente.getPort();
                //After the conexion is made, server reads a signature to
                //identify the client
               //in function process I check if the signature is valid
               //SignedData is a class where I wrap the signiture (obviously
               //it implements Serializable interface
               process((SignedData)le.LeerObject(cliente));
               //Other things done here
            catch (Exception e) { }
}le is a class I use to read,write data to the socket, this is the code of the LeerObject function
public Object LeerObject(Socket c) throws Exception {
       //Here Is where the server hangs up
        ObjectInputStream b = new ObjectInputStream(c.getInputStream());
        return b.readObject();
}As I wrote when running locally, there is no problem, but when I have a remote host, that happens
Any help or idea?

Hi again, thnx for your help
I modified my LE class so I just create a couple of Input/Output Streams per client (on server n client program), this is now the complete code of the class:
import java.net.*;
import java.io.*;
public class LE {
    DataOutputStream     dos;
    ObjectOutputStream oos;
    DataInputStream        dis;
    ObjectInputStream     ois;
    //Streams are created just once in the constructor
    public LE (Socket s) throws Exception {
        dos = new DataOutputStream(s.getOutputStream());
         //I'm not sure if this flush has any sense
        dos.flush();
        oos = new ObjectOutputStream (s.getOutputStream());
        oos.flush();
        dis = new DataInputStream(s.getInputStream());
        ois = new ObjectInputStream (s.getInputStream());
    public void EscribirByte(byte datos[],int len) throws Exception {
        dos.write(datos,0,len);
        dos.flush();

        dos.writeUTF(dato);
        dos.flush();

        dos.flush();
    public void EscribirLong(long dato) throws Exception {
        dos.writeLong(dato);
        dos.flush();

        return dis.readInt();
    public char LeerChar() throws Exception {
        return dis.readChar();
    public long LeerLong() throws Exception {
        return dis.readLong();
    public Object LeerObject() throws Exception {
        return ois.readObject();
}part of code of server and client, where the conexion is made and the LE object is created
Server:
try{
       cliente = SocketS.accept();
       //After accepting the conexion the LE object is created
        le = new LE(cliente);
        //I get client's ip and port
        String ip = cliente.getInetAddress().getHostAddress();
        int puerto = cliente.getPort();
        //Object wraping signature is read
        process((SignedData)le.LeerObject());
        //other control operations doing here
        //A thread is created to receive requests from client
        //(reference to LE object is passed to the thread
       ConexionCliente c = new ConexionCliente (cliente,id_persona,id_grupo,tipo_usuario,backup,le);
        //thread is started
        c.start();
catch (Exception e) {
    try {
        cliente.close();
    catch(Exception e2){}
}Cliente code:
try{
   //it connects to the server
   c=new Socket(host,puerto);
   //After accepting the conexion the LE object is created
   le = new LE(c);
   //other things made here to genarate SignedData Object
//It sends signed data object
le.EscribirObject(Data);
//A thread is created and started to receive messages from server
//reference to object LE is sent to the thread to avoid the need of
//creating another
new ConexionServidorClient(c,id_persona,ci,le).start();
return 1;
catch(Exception e) {
   return -1;
}after the change, itworks a little better, but still most of the times server hangs up, I can't make server operational yet and I dont have any idea for solving this issue

Write / read objects to/from File

Hello,
I have a problem with the writing and reading objects to/from a file.
So what excatly I'm trying to is:
I have a class Data. A thread creates constantly (until some limit) objects of this class Data.
Once an object is created, is placed in a buffer (I wrote my own class DataBuffer extention of LinkedList).
I have a limit on this buffer, so when the limit is reached, another thread starts getings objects from the buffer, writes them on the disk and removing them from the buffer.
I'm putting the object always on the "top" and I'm reading them and removing always from the "bottom" of the buffer (FIFO).
For writing the objects Data to the file, I'm using a FileOutputStream and ObjectOutputStream:
I have something like that:
FileOutputStream fos = new FileOutputStrea("file_name");
ObjectOutputStream oos = new ObjectOutputStream(fos);after that I have this:
while(size > i ){
                    try {
                         Data d = buff.getData();
                         //write to File
                         oos.writeObject(buff.getData());
                         oos.flush();
                         buff.removeData();
                         System.out.println("written data " + d);
                         i++;
                    } catch (IOException e) {
                         e.printStackTrace();
               }here size is the limit for the buffer.
So, when the size is equal to the total number of objects that were created and placed in the buffer, I have no problems with the writing/reading from the file.
But if size is equal, for example, to the half of the total number of objects that were created, I have a problem.
A more detailed exmple is:
10 objects were created, the 10 objects were places to the buffer, a test was made and all the objects were written on the disk -> writing and reading are OK.
if 10 objects were created, and I want to write 5 objects, and after that more 5, the first thing I remarqued is that the size of the file is different from the size of the file created by the first method. Second thing is when I'm reading from the file I can read only 5 objects and after that I have this exception:
java.io.StreamCorruptedException : invalid type code : AC
So ... is anyone has an idea why I have this problem?
PS. For reading from the file I'm using another thread that executes this code:
fis = new FileInputStream(readFile);
                    ois = new ObjectInputStream(fis);
                    while(true){
                         try{
                              Data d = (Data)ois.readObject();
                              System.out.println("data read " + d); //here I'm displaying the object that was read
                              buff.putData(d);
                         }catch(EOFException e){
                              break;
                    ois.close();
                    fis.close();
               }catch (FileNotFoundException e) {
                    e.printStackTrace();
               }catch(IOException e){
                    e.printStackTrace();
               }catch (ClassNotFoundException e) {
                    e.printStackTrace();
               }Regards,
Anton
PS. At present I'm writing first all the Data objects, and after that I'm trying to read from the file.
Edited by: anton_tonev on Oct 5, 2007 4:14 AM

Hello again :)
Finally I found the solution :)
In fact it is important to not to close the FileOutputStream and ObjectOutputStream until all the data was written on the disk.
What I mean:
in the begining of the program you have to open these two streams and write down the data that comes from somewhere.
But you musn't close these streams before the final writing on the disk.
It must look like this:
1 Open file stream & opent object stream
2 you're writing your all objects: one by one; 10 by 10 or as you wish ... but after each writing down you don't close the streams
3 you already finished with the writing, (the end of your program), now you can close the streams.
Unfortunatly I don't know why if I write the data and close the stream every time, after that it is impossible to append new data (with reopen the file)

Reading objects from a binary file works but crashes LabVIEW on exit

I've been hunting for the source of some crashes on LabVIEW exit and I was finally able to track it down to this. In my application I wrap measurements into objects that I stream into a binary file during the inspection. In another application I read the file again to browse and analyze the measurements. All this seems to work just fine except that the reading part causes LabVIEW to crash once I close the IDE. Built applications don't report any crashes but I am afraid if it might still cause some instability or unexpected behaviour.
The snippet below represents the writing and reading scheme I use and with which I am able to reproduce the problem every time. I attached the project for testing it.
Parts from the internal warning report:
#OSName: Windows 8.1 Pro N
#AppName: LabVIEW
#Version: 13.0f2 32-bit
DWarn 0xEFBFD9AB: Disposing OMUDClass definition [LinkIdentity "Class 1.lvclass" [ My Computer] even though 1014 inflated data instances still reference it. This will almost certainly cause a crash next time we operate on one of them.
Possible path leak, unable to purge elements of base #0
The full log is also attached.
Notes:
Remember: the reading works without any problems, the crash after LabVIEW exit is what I'm concerned about
Seems to only happen with classes/objects—not the default LabVIEW Object, though
Prepending array size or different byte orders make no difference
The writing is time critical, the reading is not, in case you wish to suggest other options
Has anyone else run into this? Should I be concerned for the built applications or can this be simply ruled as an IDE problem?
Solved!

Right off, if you say you can read and write lv objects, try casting your object as a lv object before saving it. The lv object is the ultimate parent of all classes.

Stream Corrupted while connection

Is there a way we can avoid this, so that connection will carry on till the game finish?

Stream Corrupted exception BLOB + Oci driver

Hi,
I have used blob which is java object and using Weblogic oci driver. So far things
are fine. I'm able to inser ,update etc.
If i change my database charset to UTF8 i get stream corrupted Exception. I'm
using weblogic 6 and is using its connection pool. i have added connection pool
settings to config.xml.
If instead of connection pool i explicitly load driver and while connecting i
add this to properties object
props.put("weblogic.oci.min_bind_size", "660");
props.put("weblogic.codeset","UTF8");
This works fine.
Now my problem is how do i set this above mentioned properties to config.xml.
any help will be appreciated.
Regards

Hi
I guess what you can do is.
Open the weblogic server console
got to the connection pool that you have
In the
Propertie
(Key=Value) textbox
write
weblogic.oci.min_bind_size=660
weblogic.codeset=UTF8
the operation will automatically write it to config.xml

I purchased a cd and it wont download one of the songs because it says its corrupt what can I do, I dont want to buy it again, I purchased a cd and it wont download one of the songs because it says its corrupt what can I do, I dont want to buy it again

After 4 repetitions I think I got that straight.
Answer: Return the CD.
Or did you mean this was an album you bought from iTunes, in which case it really isn't a "CD" (which is a hard, plastic, shiny disc) and I'm at risk of getting confused. If it is a corrupt file that you downloaded, delete the file and try downloading it again.

Hi,
In SharePoint 2013, we can take use of REST API or Client Object Model to access the SharePoint objects like Form Library.

With the retrieved file, we can then use XmlDocument object to parse it and get the values you want:

I am trying to send photos to the cloud from my phone to my iPad but they are not appearing in the stream. I have read the instructions and I think I am doing it right or am I missing a part of the process?

I am trying to send photos to the cloud from my phone to my iPad but they are not appearing in the stream. I have read the instructions and I think I am doing it right or am I missing a part of the process?

HI,
Have you done this before ? And if so, is photo stream turned on on your iphone and ipad. and as Alfred DeRose pointed out they must both on the same icloud account.
If you're new to this, you might want to do some research. Photo stream is different from camera roll and albums. Many have been on this sight looking for their photos stored in icloud after restore, etc. and they're not there. Also, after thirty days icloud deletes your photos from photo stream.
So if you're not aware, you might want to google your question. We're using the camera connection kit soon and I am learning about it. From all I've read, I'm also not the biggest icloud fan. I use dropbox. We plan to put photos taken on ipad with a camera/iphones into albums on the ipad. We'll keep all on the sd card until (and after) they can be uploaded to a computer.
An example of an article we can learn from -

Hope this helps.

How can read BOM component date before save the production order??

Hi Experts,
In our company, we need to develop a program to read the BOM component data of the production order
before we save the production order.
That for example ,when we create and release a production order , before we save the production
order,we want a porgram to read the BOM component data. If some component data can meet our
requriement (may be if there is material requirement quantity>100 EA),then the system will pop up a
small dialog box to remind us.
There is user exit PPCO0007 and PPCO0007.But it seems they only can read the head data of the
production order before we save the production order. And the BOM component data of the production
order are saved in the RESB(Reservation Table).So if we do not save the production order,all the BOM
component data are not saved in the RESB table.
So how can slove the problem??
How can read component date before save the production order??
Are there any other user exit we can use???

Hi Just wanted to check am I right that you are trying to check if you have enough Materials Available before you release or Save the order right ? if this is your business objective then when you create order you have material availability tab which checks and gives error if shortage is there. Please let me know if is this wht you asking for ?
