Socket Programming with TCP

Question

How do I do the following:
From Client1, get the file, divide into packets, send those packets to server. From there client2 will get those packets. So basically, transfer file from client1 to server and then to the client2.

Answer 1

Looked for you for Socket-example; Found this ,from
"pendraco" (so credits go to him), as an answer to some problem somewhere on page 2 (knew there had to be something)
Sorry for the shitty formatting....:
The client side is easiest:
try {    /* Open the connection     */    Socket sock = new Socket( "192.168.100.10", 2080 );    DataOutputStream dos =        new DataOutputStream( sock.getOutputStream() );    DataInputStream dis =        new DataInputStream( sock.getInputStream() );    /* Run search...     */    dos.writeUTF( "BEGIN" );    dos.flush();    String in = dis.readUTF();    while( ! in.equals( "NONE" ) ) {     // Otherwise, assume "DATA"        // handle line of data...        in = dis.readUTF();    } dos.writeUTF( "END" ); dos.flush(); sock.close();}catch( IOException ioe ) {    // Something failed...}
The server side also involves establishing the listener:
try {    /* Bind to port and wait for connection     */    ServerSocket server = new ServerSocket( 2080 );    while( running ) {        Socket sock = server.accept();        DataInputStream dis =            new DataInputStream( sock.getInputStream() );        DataOutputStream dos =            new DataOutputStream( sock.getOutputStream() );        /* Run the search...         */        String in = dis.readUTF();        if( in.equals( "BEGIN" ) ) {     // Is it the correct client?            // execute search; return line of 'data'...            if( data != null ) {                dos.writeUTF( "DATA" );                while( data != null ) {                    dos.writeUTF( data );                    // get next line of 'data'                } } dos.writeUTF( "NONE" ); dos.flush(); } in = dis.readUTF();     // assume "END" sock.close(); }}catch( IOException ioe ) {    // Something failed!}
