Java and send file through socket

I write a client-server application which will be sending an .xml file from the client to the server. I have a problem with sending large data. I notice that the server can get at most 1460 bytes. When I send a file with more than 1460 bytes the server gets only first 1460 bytes and nothng more. In effect I get uncompleted file. Here is my code:

client send:

public void sendToServer(File file) throws Exception
{
    OutputStream output = sk.getOutputStream();     

    FileInputStream fileInputStream = new FileInputStream(file);
    byte[] buffer = new byte[1024*1024];
    int bytesRead = 0;

    while((bytesRead = fileInputStream.read(buffer))>0)
    {
        output.write(buffer,0,bytesRead);
    }

    fileInputStream.close();
}

server get:

public File getFile(String name) throws Exception
{
    File file=null;

    InputStream input = sk.getInputStream();

    file = new File("C://protokolPliki/" + name);
    FileOutputStream out = new FileOutputStream(file);

    byte[] buffer = new byte[1024*1024];

    int bytesReceived = 0;

    while((bytesReceived = input.read(buffer))>0) {
        out.write(buffer,0,bytesReceived);
        System.out.println(bytesReceived);
        break;
    }

    return file;
}

Do anyone know what is wrong with this code? Thanks for any help.

EDIT:

Nothing help :(. I google about that and I think its may connected with TCP MSS with is equal 1460 bytes.
