Input Stream n Output Stream

hi,
i wrote a code for reading a file and then copying, it looks simple.
the file i m reading is in byte format n some part is of character type, but when i read this by byte Streams i wrok correctly n when i try this by using character streams it gives error,
can any one help me about this.

Sounds like a case of
"Patient: Doctor, when I do this it hurts!"
"Doctor: Then don't do that!".
When dealing with data arranged in bytes, use byte streams.

Error while executing SSIS package - Error: 4014, Severity:20, State: 11. A fatal error occurred while reading the input stream from the network. The session will be terminated (input error: 109, output error: 0)

Hi,
We are getting the following error when running our SSIS packages on Microsoft SQL Server 2012 R2 on Windows Server 2008 R2 SP1:
Error: 4014, Severity:20, State: 11. A fatal error occurred while reading the input stream from the network. The session will be terminated (input error: 109, output error: 0)
SQL Server Data Tools and SQL Server Database Engine reside on the same server.
We tried the following:
Disabling TCP Chimney Offload
Installed Windows Server 2008 SP1
Splitting our SSIS code into multiple steps so it is not all one large continuous operation
The error occurs during a BulkDataLoad task.
Other options we are investigating with the engineering team (out-sourced, so delayed responses):
Firewall configurations (everything is local, so this should not make a difference)
Disabling the anti-virus scanner
Are there other things we can try?
Any insight is greatly appreciated.
Thanks!

Hi HenryKwan,
Based on the current information, the issue can be caused by many reasons. Please refer to the following tips:
Install the latest hotfix based on your SQL Server version. Ps: there is no SQL Server 2012 R2 version.
Change the MaxConcurrentExecutables property from -1 to another one based on the MAXDOP. For example, 8.
Set "RetainSameConnection" Property to FALSE on the all the connection managers.
Reference:

If the issue is still existed, as Jakub suggested, please provide us more information about this issue.

Separate thread for input stream and output stream.

Hi Techies,
In a socket connection, can we run the input stream and output stream in separate threads. actually in my case, the input stream will be getting the input regularly and output stream will send data very rare. so if i impelment them in one class then unless there is data to send output stream will be blocked. i was thinking to impelment both the streams in separate threads. is it a good way? so how to implement it. your guidance will be of great help.
thanks in advance.

Iis it a good way? so how to implement it. your guidance will be of great help.Once you have a socket, create two threads, one which does the reading and one which does the writing.
You could use BlockingQueues to abstract access to these threads. i.e. the reading thread reads something from the socket and adds it to the BlockingQueue. The writing thread take()s something froma second BlockingQueue and writes it to the Socket. This way you add things to write or get thing to process by looking at the BlockingQueues.

When using URLConnection read input stream error

Thanks.
My main code:
APPLET:(TestApplet)
URL url = new URL("http://210.0.8.120/jsp/test.jsp";
URLConnection con;

you have to pay attention to the sequence of opening the streams.
The following example is: client sends a string to server, and servlet sends a response string back.
client side:
         URL url = new URL( "http://152.8.113.149:8080/conn/servlet/test" );
         URLConnection conn = url.openConnection();
         System.out.println( "conn: " + conn );
         conn.setDoOutput( true );
         conn.setDoInput( true );
         conn.setUseCaches( false );
         conn.setDefaultUseCaches (false);
         // send out a string
         OutputStream out = conn.getOutputStream();
         ObjectOutputStream oOut = new ObjectOutputStream( out );
         oOut.writeObject( strSrc );
         // receive a string
         InputStream in = conn.getInputStream();
         ObjectInputStream oIn = new ObjectInputStream( in );
         String strDes = (String)oIn.readObject();server side
         // open output stream
         OutputStream out = res.getOutputStream();
         ObjectOutputStream oOut = new ObjectOutputStream( out );
         // open input stream and read from client
         InputStream in = req.getInputStream();
         ObjectInputStream oIn = new ObjectInputStream( in );
         String s = (String)oIn.readObject();
         System.out.println( s );
         // write to client
         oOut.writeObject( s + " back" ); I have the complete example at http://152.8.113.149/samples/app_servlet.html

Sending Control-Z to Input Stream

Hi everyone,
I'm writing an interface to a command line program, and
one of it's features is that it will accept "forms" through
standard input. The default is that notepad will open
when the command is typed, and you can edit the form
through there.
To accept the form through standard input, you have to
send it the form, and then tell it the form is complete.
This is done using the CTRL-Z keypress, at least when
typing the form in with the keyboard.
I need to do this with Java.
There is another post which poses the same question at
http://forum.java.sun.com/thread.jsp?forum=1&thread=3050
so I attempted that solution.. and that didn't work.
I had the system print out the form as it was being written,
and the form displayed properly, followed by what was
supposed to be a CTRL-Z character, which appeared
on screen (DOS Window) as an arrow pointing right.
Here is the code constructing the form and adding what i've been told is "ctrl-z":
new StringBuffer(form+System.getProperty("line.separator")).append(CTRL_Z).append(System.getProperty("line.separator")))CTRL_Z is defined as:
public static final char CTRL_Z = 26;Does anyone have any other suggestions that might be able to help me?
If you need more information/code provided, I can do so.
Thanks for any help!
Kefka.

You can't actually send anything to an input stream. But let's suppose you have an output stream somewhere that is connected to the standard input of this command line program. Try sending a byte, not a character, that contains 26 to it (yes, ctrl-z is indeed 26). This has a better chance of working than the character idea, because Java is going to translate your character-26 from Unicode to bytes using your system's default encoding. And I can't predict what that might end up as. But it will leave the byte 26 alone and just send it... I hope. Can't guarantee this.

My suggestion would be to run your code as a plain old Java application. Why use a servlet environment to test the problem? There's just too many things going on. So first see if it works the same way in a Java application. If it does, or if it doesn't, you then know where to go next.

Playing input stream audio in j2me

want to make a text-to-speech synthesizer for mobile phones.
for that i am using FreeTTS (text-to-speech synthesizer written in java)
so i have made a client-server model where i have a midp client which is sending text to the FreeTTS acting as a server.... for this i am using socket...
so basically -- client is sending text to server -- server processes the text and sends the audio stream back to client
the problem is i dont know how to play the audio stream received on client side
i tried to copy it in a buffer but its not working..
do i need to save the file in some format before playing it?
or can the player play the audio stream directly?
this is how i am copying the contents in the buffer
try
InputStream is = socketConnection.openInputStream();
byte[] buff = new byte[1024];
int bytesIn = is.read(buff, 0, 1024);
ByteArrayInputStream bis = new ByteArrayInputStream(buff);
player = Manager.createPlayer(bis, "audio/x-wav" );
player.start();
but it gives an error saying
javax.microedition.media.MediaException: Malformed wave media
i tried to display the contents of bis on console it reads
java.io.ByteArrayInputStream@d590dbc
i tried the same with the Free TTS client and got the same output.
so i think client socket is even receiving the audio stream properly...however, im not sure.
is the whole client-server using socket idea correct?
if yes, please tell me how to play this audio stream in j2me (the client)
if it is wrong then please tell me a correct way to do this.
can the input stream be stored as a WAV file and then played? if yes, then how can i store it as a WAV file? Can this be achieved by appending a WAV header?

I once tried the similar thing, I ended up buffer all the content locally (from bluetooth), then play the wave file.
Maybe someone else has better idea.

Re: Connection Failure: ReadFile on fd=1231 failed with err=64 + JVM_recv in socket input stream read

Jon,
I believe that this error is similar to a "connection reset by peer". It is
a Window specific error. I believe it indicates that something has happened
on the other end of the socket such that the socket has gone bad.
I think that this should only occur when people reset their connection
before the reply is sent. I don't believe that it is indicative of any
serious problem other than this communication failure caused by the client.
I've opened an issue to catch and squelch these spurious exceptions rather
than logging them. For now I think it is safe to ignore them.
Regards,
Adam

Hi Guys,
Using weblogic 5.1 (downloaded pretty soon after announcement) on windows
2000 (yes I know not certified there yet) and using jdk1.2.2-001.
I have a pretty standard setup - a connection pool (5) to a sqlserver
(remote) machine.
A pretty standard multithreaded servlet - grabs a connection, does aselect,
calls dbkona to dump output, releases connection.
It runs fine - browser returns result. When I push 'reload' on browser,say
10 times very quickly, I get the following errors. It is sometimes a
combination of these:

Now I can get rid of (1) by switching off native IO!! This also stoppedIO
exceptions that were being raised by the servlet when it tried to outputto
the output stream. (2) persists.
I have changed nothing else in the properties.
(1) sounds like I may need to up the number of file descriptors open?
(2) I don't know. Is my server too loaded? I am running on a 600Mhzusing
64Mb heap for the server with 300Mb swap available...

Jon

As I am repeatedly hitting the server from one browser, your 'connection

applies quite well.
(btw. before the SP, the errors seemed to crop up more just before/during
a
GC.)

Connection Failure: ReadFile on fd=1231 failed with err=64 + JVM_recv in socket input stream read

Hi Guys,
Using weblogic 5.1 (downloaded pretty soon after announcement) on windows
2000 (yes I know not certified there yet) and using jdk1.2.2-001.
I have a pretty standard setup - a connection pool (5) to a sqlserver
(remote) machine.
A pretty standard multithreaded servlet - grabs a connection, does a select,
calls dbkona to dump output, releases connection.
It runs fine - browser returns result. When I push 'reload' on browser, say
10 times very quickly, I get the following errors. It is sometimes a
combination of these:
1- Mon May 08 13:34:41 GMT+00:00 2000:<E> <HTTP> Connection failure

Now I can get rid of (1) by switching off native IO!! This also stopped IO
exceptions that were being raised by the servlet when it tried to output to
the output stream. (2) persists.
I have changed nothing else in the properties.
(1) sounds like I may need to up the number of file descriptors open?
(2) I don't know. Is my server too loaded? I am running on a 600Mhz using
64Mb heap for the server with 300Mb swap available...

Jon

IOException: Connection reset by peer: JVM_recv in socket input stream read

hi
I encountered a problem : a program throw out an exception:java.io.IOException: Io exception:
Connection reset by peer: JVM_recv in socket input stream read.
I tried my best to resolve it ,but unfortunately,i didn't know what caused the exception.
the following is my application environment:
I have two PC(Win2000os),one is a server which installed oracle9.2.0.2 and jdeveloper9.0.3,the another is a
client which only intalled jdeveloper9.0.3.Two days ago,i performed a web application on my client with
jdeveloper,and it includes some JSP and a javabean files.JSP Page finished uploading client xml file to a
folder on server and the javabean finished loading the xml file into a xmltype column.I can make sure the
connection is established and the javabean is OK,beacause my some jsp page can successfully use
<jsp:usebean> tag and use the javabean's some other public interfaces,except the interface that finishs
loading the xml file into a xmltype(clob) column.
Then i do many tests!I changed the javabean to a java class incluse a main method beacause it is easy to
debug.Finally i found the following code caused the exception:
public CLOB writetoClob( CLOB clob, InputStream is )throws SQLException, IOException {
InputStreamReader reader = new InputStreamReader( is );
Writer writer = clob.getCharacterOutputStream( );
char[] buffer = new char[clob.getChunkSize( )];
int charsRead;
for ( charsRead = reader.read( buffer ); charsRead > -1;charsRead = reader.read( buffer ) ) {
writer.write( buffer, 0, charsRead );
writer.close();
return clob;
when it runs to writer.close(),the exception is caused!
Then i copy the java class to the server,it runs ok!
That is to say ,the same code,the different result!
But when i run my web application on server with jdeveloper Embedded OC4J Server and a jsp page loaded javabean
and run to mentioned code ,the same exception occured!
I checked the application log in event viewer,the descriptions was:
The data buffer created for the "AppleTalk" service in the "C:\WINNT\system32\atkctrs.dll" library is not
aligned on an 8-byte boundary. This may cause problems for applications that are trying to read the
performance data buffer. Contact the manufacturer of this library or service to have this problem corrected or
to get a newer version of this library.
I search some some resolution about this exception with web and someone sayed :
This basically means that a network error occurred while the client was receiving data from the server. But
what is really happening is that the server actually accepts the connection, processes the request, and sends a
reply to the client. However, when the server closes the socket, the client believes that the connection has
been terminated abnormally because the socket implementation sends a TCP reset segment telling the client to
throw away the data and report an error.
Sometimes, this problem is caused by not properly closing the input/output streams and the socket connection.
Make sure you close the input/output streams and socket connection properly. If everything is closed properly,
however, and the problem persists, you can work around it by adding Thread.sleep(1000) before closing the
streams and the socket. This technique, however, is not reliable and may not work on all systems.
In general,the following information is conclution:
Web application runs error both on client and on server.
If it was changed to a client java class,it only run ok on server!
i have done anything that i can do now,i feel depressed very much!
how can i resolve the problem!
Any a little help will be appreciated!
regards!
Thanks

Server Socket does not read data input stream

Hi all,
I am very newbie to Java Network programming with sockets and multi-threading.
But I am obliged to develop a chat system written in Applets which can be placed on the website and used by visitors who come to my website.
In order to understand this, I have tested a basic web chat program I downloaded from the Internet which use sockets and multi-threadings. The program work fine, no bugs at all at both compilation and run time. I noticed that all three streams for Client side (i.e. first one is input stream used receiving data from User; the second one is socket input stream used for receiving data from Server socket, and the third is socket output stream used for writing data to server socket) were established. And the same, two socket streams (input & output) for Server side were also connected when running program giving right port number and IP address of the server.
The problem is both server and client sockets do not read data using the following stream classes:
1. DataStreamInput: I use input.readUTF() method
2. or BufferedReader: I use input.readLine() method
The example of the codes are below:
private BufferedReader input = null;
private PrintWriter output = null;
private Socket socket = null;
public void open() throws IOException
{ input = new BufferedReader(new
InputStreamReader(socket.getInputStream()));
System.out.println("Server socket input stream was created, and");
output = new PrintWriter(socket.getOutputStream());
System.out.println("Server socket output stream was created");
public void run()
{ System.out.println("Server Thread " + clientPort + " running.");
while (true)
{ try
System.out.println("Server is reading data from Client, wait...");
String fromClient = input.readLine();
System.out.println("Server received a message on " + clientPort + ".");
catch(IOException ioe)
{ System.out.println(clientPort + " ERROR reading: " + ioe.getMessage());
server.remove(clientPort);
stop();
The problem is at the line: String fromClient = input.readLine(); in the run() method? What is wrong with the codes above?
Note: I also try to use original codes which use readUTF() method in DataStreamInput class instead using readLine() in BufferedReader. Both methods dont read data from inputstream socket?
I very appreciate any help/advice from experienced developers.
Best regards

Hi,
Yes. The readLine() method hangs! After the test, the execuation of the program is stopped at the line of readLine() method; it does not pass it?
There is no problem with writing to Server socket. After the test, the program pass through flush() method. Here is the code for writing to sever socket within ChatClient (client side socket) class:
private BufferedReader input = null;
private PrintWriter           output = null;
public ChatClient(String serverName, int serverPort)
{ System.out.println("Establishing connection. Please wait ...");
try
{ socket = new Socket(serverName, serverPort);
System.out.println("Connected: " + socket);
start();
catch(UnknownHostException uhe)
{ System.out.println("Host unknown: " + uhe.getMessage()); }
catch(IOException ioe)
{ System.out.println("Unexpected exception: " + ioe.getMessage()); }
public void start() throws IOException
{ input   = new BufferedReader (new
                         InputStreamReader(System.in));
System.out.println("Client User input stream was created,");
output = new PrintWriter(socket.getOutputStream());
System.out.println("Client Socket output stream was established, and");
if (thread == null)
{ client = new ChatClientThread(this, socket);
thread = new Thread(this);
thread.start();
public void run()
     while (thread != null) {
     String fromUser;
          try{
               while((fromUser = input.readLine())!= null)
               System.out.println("Client wasreading a data from User, and");
output.println(fromUser);
     output.flush();
     System.out.println("Client has written a data to Server");
catch(IOException ioe)
{ System.out.println("Sending to server error: " + ioe.getMessage());
stop();
etc.
Here is a piece of codes for reading data from the Client Socket in the ChatServer Class (Server Side socket):
public void run()
{ System.out.println("Server Thread " + clientPort + " running.");
while (true)
{ try
{ //server.handle(clientPort, input.readLine());
System.out.println("Server is reading data from Client, wait...");
String fromUser = input.readLine();
//while((fromUser = input.readLine()) != null)
     System.out.println("Server received a message on " + clientPort + ".");
catch(IOException ioe)
{ System.out.println(clientPort + " ERROR reading: " + ioe.getMessage());
server.remove(clientPort);
stop();
etc. Please advice why the readLine() method hangs; does not read data from the input stream received from the CLIENT?

Problem reading input stream of urlconnection within portal

Hi,
This may be a generic server issue rather than portal but since it's my portal app that's displaying the problem I'll post it here.
Part of my Portal attempts to POST to a remote server to retrieve some search results.
In environments A & B (both standalone instances) this works fine.
In environment C this works on the managed instances in the cluster but not the admin instance.
In environment D (again standalone) it fails, but if I add a managed instance it works from the managed instance.
The problem I'm seeing is that I get a stuck thread and the thread dump shows it is blocked attempting to read the resulting input from a urlconnection. (Using a buffered input stream).
I've copied the code to a standalone class that runs fine from the same server(s). I've pasted this code below, the contents of the test() method were copied directly from my webapp (urls changed here for clarity).
Does anyone know of any securitymanager issues that may cause this?
Or anything else for that matter?
Code sample:
package src.samples;
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;

public class POSTTest {
     public static boolean test()
     URL url = null;
     try {
     url = new URL
("http://hostx:80/myapp/search.html");
     catch (MalformedURLException e)
     e.printStackTrace();
     return false;
     URLConnection urlConn;
     DataOutputStream printout;
     BufferedReader input;
     urlConn = null;
     try {
     urlConn = url.openConnection();
     catch (IOException e)
     e.printStackTrace();
     return false;
     // Let the run-time system (RTS) know that we want input.
     urlConn.setDoInput (true);
     // Let the RTS know that we want to do output.
     urlConn.setDoOutput (true);
     // No caching, we want the real thing.
     urlConn.setUseCaches (false);
     // Specify the content type.
     urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
     // Send POST output (this is a POST because we write then read as per the JDK Javadoc)
     printout = null;
     String body = "";
     try {
     System.out.println("url=" + url.toString());
     printout = new DataOutputStream (urlConn.getOutputStream ());
     String content = "param1=A&param2=B&param3=C&param4=D&param5=E";
     System.out.println("urlParams= " + content);
     printout.writeBytes (content);
     System.out.println("written parameters");
     printout.flush ();
     System.out.println("flushed parameters");
     printout.close ();
     System.out.println("closed parameter stream");
     // <b>Get response data - this is where it blocks indefinitely</b>
     input = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));
     System.out.println("got input");
     String str;
     while (null != ((str = input.readLine()))) {
     body = body + str + "\n";
     System.out.println("read input:");
     System.out.println(body);
     input.close ();
     System.out.println("closed input stream");
     catch (IOException e) {
     System.out.println("IOException caught: read failed");
     e.printStackTrace();
     return false;
     return true;
     * @param args
     public static void main(String[] args) {
          System.out.println("Test result= " + test());

In your recuperar() method, read the FTP input stream into a byte array. (You can do that by copying it to a ByteArrayOutputStream and then getting the byte array from that object.) Then, return a ByteArrayInputStream based on those bytes. After you call completePendingCommand(), of course.
That's one way.

Unexpected end of ZLIB input stream.

Hello everyone.
I have a problem which I was unable to solve so far. Any suggestion is very welcome.
The scenario.
My process worked on a previously installed default install 10.1.3.1 platform.
I installed the SOA Suite (same, very default set with olite) on a different computer and copied all files of the project dir. Modified file paths and URLs in all files in the folder and deployed the process with jdeveloper.
Symptoms.
Flow viewer gets stuck at Loading audit trail. Messages from a java call get to manual recovery, and will not recover.
I start the process with a java call:
Locator locator = new Locator("default","bpel");
IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME);
NormalizedMessage nm = new NormalizedMessage( );
nm.addPart("payload", xml );
deliveryService.post("OrderFlow", "initiate", nm);
it starts without any problems and runs until a callback (receive) activity, where it is waiting for a message using the same java api calls as above.
This runs well on the previous system, however the new system will not deliver the message.
Log output.
After trying to access the flow viewer:
<2008-03-19 20:13:12,120> <ERROR> <default.collaxa.cube> <BaseCubeSessionBean::logError> Error while invoking bean "instance manager": Cannot uncompress data stream.

THANK YOU

Some update on the issue.
I have a quite complicated BPEL process, which has this symptom.
I figured out however, that if I dont use the TaskService, it does run well.
So I just created a test bpel process with nothing but a human task.
It failed with the same unexpected end of zlib ... problem.
What I also noticed is that the task appears in the worklist app, but the reply gets into the callback manual recovery pool. there must be some kind of communication failure from the taskservice in the direction of the bpel process.
Any advice is welcome,
thx,
tg

Re: File Input Streams FileNotFoundException

Hi,
I'm having problems with file input streams.
The program is supposed to read from an external file but when I run it in Sun ONE Studio 4 (update 1), it gives me a FileNotFoundException (The system cannot find the file specified). The file, class.dat, is in the same folder as the .java and .class files.
Anyway, so I run the program through MS-Prompt commands and there is no problem. It executes fine and gives the right output. Go figure.
Can anyone shed some light on what is going on? Anyone else with the same problem? Is there something I need to configure in SunStudio? Please help...
Thanks
The code is taken directly from Sams Java in 21 days.
// code
import java.io.*;
public class ReadBytes {
public static void main(String[] arguments) {
try {
FileInputStream file = new
FileInputStream("class.dat");
boolean eof = false;
int count = 0;
while (!eof) {
int input = file.read();
System.out.print(input + " ");
if (input == -1)
eof = true;
else
count++;
file.close();
System.out.println("\nBytes read: " + count);
} catch (IOException e) {
System.out.println("Error -- " + e.toString());

FileInputStream file = new FileInputStream("class.dat");Is this the line that is giving you the error message? Always, when trying to open a disk file, give the full path. This is because, FileNotFoundException is thrown only in cases when your file cannot be found by your program. But you say that the file exists.
Try giving your full path for the file...like:
FileInputStream file = new FileInputStream("C:/Program Files/class.dat");
//Ofcourse your path will be different. This is just an example!So try giving the full path and let me know.
