Send a image through socket method getoutputstream

cani send an image through socket methods instead of send a txt

1) Use the search feature, or look back a couple of pages, this question was asked sometime yesterday
2) In all the many times that it's been asked, no-one denies it but at the same time no-one's posted any code to do it (AFAIK) I'd be interested too if anyone does find a way...

Sending an image using sockets

can anybody give an idea about how to send an image using sockets.....
what i want to do is a client that connects to a server this server has the images...so the client request any image that the server has and display it int the client's frame

Very good point! The problem ( I told you it was untested!) with the above is that the Image class isn't actually serialisable.
The solution depends on how you're storing your images and how you're managing them within your server. It also depends on your proposed client. For example, if your client was a browser and your images files on a disk, then you might use:
                    Socket s;
                    // Write out header
                    PrintWriter pw = new PrintWriter(s.getOutputStream());
                    pw.println("Content-Type: image/gif");
                    // And send out data.
                    byte[] buffer = new byte[2048];
                    int count;
                    while((count = fis.read(buffer))>0) {
                         s.getOutputStream().write(buffer, 0, count);
                    s.getOutputStream().close();
               }although you'd probably be better off using a proper webserver. If you're using a proprietry client, then you can either use Swing's JEditorPane to act like browser and display the image as the server above presents it.
Otherwise, your client could use the incoming byte stream to create a BufferedImage instance.
How are you storing your images and how are you presenting them?

How can I send an image through a WebService

Hi,
I'm trying to send an image through a WebService to a mobile phone, but I can't get it working.
Anyone knows how I can send an image on the server side, and receive it on the client side?
Thanks for your help.

Send a message through socket

Hi
I want to send a MIMEMessage through socket. And want to receive the same.
Could any one help me out ?

Hi
I proceed that thing.
I am getting the problem while converting the input stream from socket to MIME message.
I am getting prob at following line.
//soc is the object of Socket
Session session =Session.getDefaultInstance(new Properties(), null);
MimeMessage l_msg = new MimeMessage(session, soc.getInputStream());When I read the input stream from the file.
It works successfully. But when I try to get it from socket not doesn't work.
It's not showing any error also. So I am not able to track the actual error.
Could you please tell me why it is not working.

Reading and Writing Image through Socket

hi
i'm doing a mobileapplication and i send the Image from the server using a DataOutputStream. I'm converting the Image to a byteArray. The Image in .png format. But i need to read it from a J2ME application and when i read the byteArray and convert it to a Image it gives a illegalArgumentException coz it says that cannot decode the Image.
Can anyone Help
Rushi

some png files are not standard png files thats why u may get the error but u should try like this:
Server side=>
OutputStream os=c.getOutputStream();
int numBytesRead = 0;
while ((numBytesRead = input.read(buf)) != -1) {
os.write(buf, 0, numBytesRead);
Client side=>
bStrm=new ByteArrayOutputStream();
c = 0;
while ((c=dis.read())!=-1)
bStrm.write(c);
imgData = bStrm.toByteArray();
bStrm.close();
img=Image.createImage(imgData,0,imgData.length);

Sending 2 objects through sockets?

Hi there,
I have 2 questoins here...
The first is....
Ive made a simple game that moves a image around a screen using the arrow keys. When i start the server it listens for connections and then I run the client. I'm able to get 2 instances of the objects running in 2 different swing frames but at the moment when I move the image around the screen it only moves in one window and not in the other. I would like the coordinates of the image in one window to be the same as the other when I move it.
this is my server class...
public void run() {
           try {
              oos.writeObject(pgf.getPacmanGamePanel().getPacmanGame());
              oos.writeObject(pgf.getPacmanGamePanel().getGhost());i move the pacmanGame on my PacmanGamePanel(pgp) which is on a pacmanGameFrame(pgf)
This is my Client class....
public static void main(String argv[]) {
            PacmanGameFrame pgf = new PacmanGameFrame();
           ObjectOutputStream oos = null;
           ObjectInputStream ois = null;
           //ObjectInputStream ois2 = null;
           Socket socket = null;
           PacmanGame pacgame = null;
           Ghost ghost = null;
           int port = 4444;
           try {
             // open a socket connection
             socket = new Socket("localhost", port);
             // open I/O streams for objects
             oos = new ObjectOutputStream(socket.getOutputStream());
             ois = new ObjectInputStream(socket.getInputStream());
             //ois2 = new ObjectInputStream(socket.getInputStream());
             while (true) {
                    // read an object from the server
                    pacgame = (PacmanGame) ois.readObject();
                    ghost = (Ghost) ois.readObject();
                    oos.reset();
                    I was hoping you could tell me why its not sending the object over from my client.
The second thing is i've coded a Ghost class the exact same way as my PacmanGame class which contains how the image moves around the screen and its methods etc. For some reason its not displaying at all on either the client or the server when i try to send the object across.
I am trying the same way as sending the pacmanGame() but it doesn't work....
public void run() {
           try {
              oos.writeObject(pgf.getPacmanGamePanel().getPacmanGame());
              oos.writeObject(pgf.getPacmanGamePanel().getGhost());I have a panel class which prints out the coordinates of the ghost

            g2d.drawImage(pacmanGame.getImage(), pacmanGame.getX(), pacmanGame.getY(), this);
        for (int i = 0; i < ghosts.size(); i++) {
             Ghost ghost = (Ghost)ghosts.get(i);
             if(ghost.isVisible())
                  g2d.drawImage(ghost.getImage(), ghost.getX(), ghost.getY(), this);

        else {
             System.out.println("GAME OVER");
        Toolkit.getDefaultToolkit().sync();
        g.dispose();
    }Help on either question would be great.
1. why wont the image move on both server and client sides.
2. How can i get my ghost class to display?
If you need more info/code let me know..
Thanks alot.

Ok i called flush() on the output and commented out reset() on the input but still the same problem.
oos.writeObject(pgf.getPacmanGamePanel().getPacmanGame());
              oos.writeObject(pgf.getPacmanGamePanel().getGhost());
              oos.flush();
pacgame = (PacmanGame) ois.readObject();
                    ghost = (Ghost) ois.readObject();I think i've figured it out now and its to do with my paint() within gamePanel..
public class PacmanGamePanel extends JPanel implements ActionListener {

Send encypted bytes through socket

I am trying to send some encypted bytes to another socket, and I use the code below:
byte[] encrypted = encrypt(myString);
DataOutputStream ostream = new DataOutputStream(socket.getOutputStream());
ostream.writeInt(encrypted.length);
ostream.write(encrypted);
To receive:
DataInputStream istream = new DataInputStream(socket.getInputStream());
byte[] encrypted = new byte[istream.readInt()];
istream.read(encrypted);
String decrypted = decrypt(encrypted);
But the bytes I received was wrong, can somebody give me any idea about it?

You should be using the
write(byte[], int, int) method to write your byte array to the
DataOutputStream (and the read(byte[]) or read(byte[], int, int) for reading).
They are more efficient then using the writeByte type methods. And you
may avoid some of the problems you are getting. If the problems persist
ensure that your encryption and decryption are working properly.

Send key sequence through socket.

Hi!
I have programmed an application which makes a socket-connection to a telnet-server. All this have went good. The problem I'm having is sending keysequences. Let's say that I want to perform a "Ctrl-c"... how do I do this?

You may have to listen for keyPressed method calls (KeyListener), not just keyTyped, to watch for the control key being pressed. If you see the control key pressed, begin your translation into control characters or special key sequences. Then when keyReleased says the control key has been released, stop your translation.
e.g. I believe the CTRL plus the keypad Minus key do not send an intelligent keyPressed event. So you'll have to watch for the combination yourself, then send the codes you want to represent that down the stream.

Send email with html and images over Sockets

Hi! I'm sending email messages through sockets with html. So far is working great. But now, I need to include images in the html code, like a web page. I don't have any idea on how to do this. Sending image apart from the html code is not big deal, but how to put it in the code. I mean how to make this html code, work:
<table border="0">
     <tr>
          <td>Image in code</td>
     </tr>
     <tr>
          <img src="what to put here"/>
     </tr>
</table>This is the code that I'm using to send the html mail:
StringBuffer retBuff = new StringBuffer();
          //BufferedReader msg;
          //msg = new BufferedReader(msgFileReader);
          smtpPipe = new Socket(mailHost, SMTP_PORT);
          smtpPipe.setSoTimeout(120000);
          if (smtpPipe == null) {
               return retBuff;
          inn = smtpPipe.getInputStream();
          outt = smtpPipe.getOutputStream();
          in = new BufferedReader(new InputStreamReader(inn));
          out = new PrintWriter(new OutputStreamWriter(outt), true);
          if (inn == null || outt == null) {
               retBuff.append("Failed to open streams to socket.");
               return retBuff;

          retBuff.append(initialID);
          retBuff.append("HELO " + localhost.getHostName());
          out.println("HELO " + localhost.getHostName());
          String welcome = in.readLine();

          //out.println("Content-Transfer-Encoding: 7bit;");
          //String line;
          //while ((line = msg.readLine()) != null) {
          //     out.println(line);
          out.println(msg);
          retBuff.append(".");
          out.println(".");
          String acceptedOK = in.readLine();
          retBuff.append(acceptedOK);
          retBuff.append("QUIT");
          out.println("QUIT");
          return retBuff;

Throw all this away and use one of the numerous existing Java mail packages, such as javax.mail for a start.

Send Image through xml file

Hey guys,
I want to send an JPEG image through xml file. i dont want to just give the URL of the image but i want to actually send the image through xml. Im new in XML so can you please give me a working sample code.
Thank you so much.

Working code will not be difficult to write. Jpeg or other binary info can be encoded in xml using base64 encoding or some other encoding algorithm.
After base64 encoding you will get some text which will be the base64 equivalent of the image data. This text can be placed in CDATA section of your image element and transferred.
On the receiving end you will need to decode the text. After this what u have is the binary data for ur image.
It will not be difficult to find libraries for base64 encodin/decoding on the net.
Hope it helps

Phone won't send image through Messages

I currently have an iPhone 5 (iOS 7.1.1) and for the last week I haven't been able to send any image through Messages. I'll hit send, and it will show delivered, but after 10-15 seconds it pops up with the red exclamation point and says "Not Delivered." I've tried a hard restart on my phone, turning off wi-fi to see if that was the issue, and checked through my Settings. Everything seems to be in order, but I still can't send them. The only way they will go through is if I send as a Text Message, which is frustrating. Has anyone else had this same issue? Is there a way to fix it? Thanks for any help that you can give!!

Hi kathim79,
Welcome to the Apple Support Communities!
I understand that you are having issues sending MMS messages with iMessage. It sounds like you have already done some good troubleshooting. At this point I would suggest the steps in the following article to help isolate and resolve this issue.

Logging through sockets

Hi
I'm trying to send logging information through sockets using log4j.
My configuration file is :
log4j.rootLogger=Debug, Socket
log4j.appender.Socket=org.apache.log4j.net.SocketAppender
log4j.appender.Socket.Port=12345
log4j.appender.Socket.RemoteHost=localhost
log4j.appender.Socket.LocationInfo=true
the server only reads the input string that the logger sends.
I'm getting this exception on the client side:
log4j:WARN Detected problem with connection: java.net.SocketException: Software caused connection abort: socket write error
and this message on the server:
Server started...
Client accepted
��org.apache.log4j.spi.LoggingEven��

Ryan,
I think if I could log to something common like Microsoft Access it would be a help to me in managing database backups and other things, as Citadel is somewhat unique in its format and methods using the Measurement and Automation Explorer. Maybe I could retrieve data from a 3rd party database back into Citadel if Citadel DB becomes corrupted or lost.
I don't use ODBC logging now, so please excuse me if I come across as lacking in understanding your request. Could the hypertrend or other objects be programmed to log and/or retrieve data to and/or from the 3rd party ODBC database as well?

Why won't iMessage send/receive PICTURES through my iPad, iPhone, and MacPro on Wifi?

For the last 2 weeks or so, I haven't been able to send/receive images through the iMessage application on either of my iPad, iPhone 4S, or MacPro. I have tried different Wi-fi connections, I have deleted/re-added email addresses to which I can be reached at/send messages and tried sending different pictures...all unsuccessfully. I try sending them, they say "Delivered" for a moment and then switch to saying "Not Delivered" (in red). I have tried to confirm with other people if they receive the pictures I send, regardless of me seeing the "Not delivered" message, but they say that they didn't receive anything. I have only been able to send pictures once in the last 2 weeks. Can anyone help me with this?

Sockets: can only send once file through

Hi,
I am using sockets to send text and files to a client on a Clio. I want to send multiple files through. However, only the first file goes through. The rest are never received (although they are uploaded). My question is:
Why can not send anything through the socket (text or files) after the first file is sent?
The fileSend() is on the server side, fileReceive is on the client side.
public static void fileSend (Socket uploadSocket, String source) {
     try {
         InputStream inFile = new FileInputStream(source);
         InputStream in = new BufferedInputStream(inFile);
         OutputStream out = new BufferedOutputStream(uploadSocket.getOutputStream());
         System.out.println("Sending " + source + ".");
         int data;
         int bytes = 0;
         while ((data = in.read()) != -1) {
          bytes++;
          out.write(data);
         bytes++;
         out.write(data);
         if (in != null) in.close();
         if (out != null) out.flush();
         System.out.println("Upload complete: " + bytes + " Bytes!");
     catch (Exception e) {
         System.err.println("Couldn't upload " + source + ": " + e.getMessage());
   public static void fileReceive (Socket downloadSocket, String destination) {
     try {
         InputStream in = new BufferedInputStream(downloadSocket.getInputStream());
         OutputStream outFile = new FileOutputStream(destination);
         OutputStream out = new BufferedOutputStream(outFile);
         System.out.println("Downloading data to " + destination + ".");
         int data = in.read();
         int bytes = 0;
         while (data != -1) {
          bytes++;
          out.write(data);
          data = in.read();
         bytes++;
         if (out != null) {
          out.flush();
          out.close();
         outFile.close();
         System.out.println("Download complete: " + bytes + " Bytes!");
         in.skip(in.available());
     catch (Exception e) {
         System.err.println("Couldn't download " + destination + ": " + e.getMessage());
    }Thanks,

I think its better to pass the outputstream to the filesend() method and inputstream to fileReceive() method
something like this:
OutputStream out = new BufferedOutputStream(uploadSocket.getOutputStream());
public static void fileSend (OutputStream os, String source) {
//write your file onto the output stream
InputStream in = new BufferedInputStream(downloadSocket.getInputStream());
public static void fileReceive (InputStream is) {
//Read from the input stream
}This should work.. Good luck
