I try to establish a connection to a SSL socket server , by using ssl
socket client (code below) and I got an exception, can you help me pls?
The server is ok I did a connection with sslopen client.
thanks

public class ClientSSL {
    static int port = 1111;

    static String hostname = "myIP";

    public static void main(String[] arstring) {
        try {
            SSLSocketFactory sslsocketfactory =(SSLSocketFactory) SSLSocketFactory
                    .getDefault();
            SSLSocket sslsocket = (SSLSocket) sslsocketfactory.createSocket(
                    hostname, port);
             String[] prot = new String[1];
             prot[0]="SSLv3";
        sslsocket.setEnabledProtocols(prot);

            String[] newcipher = new String[1];
            newcipher[0]="TLS_DH_anon_WITH_AES_128_CBC_SHA";

            sslsocket.setEnabledCipherSuites(newcipher);

            String[] cipher = sslsocket.getEnabledCipherSuites();
            for(int i=0;i<cipher.length;i++){
             System.out.println(cipher[i]);
            }

            OutputStream outputstream = sslsocket.getOutputStream();
            BufferedOutputStream outbuff = new BufferedOutputStream (outputstream);

            byte[] test = new byte[4];
             test[0]=8;
             test[1]=1;
             test[2]=3;
             test[3]=6;

            outbuff.write(test);
            outbuff.flush();
            sslsocket.close();
        } catch (Exception exception) {
            exception.printStackTrace();
        }
    }

}

output:
TLS_DH_anon_WITH_AES_128_CBC_SHA
