关于SSL的javax.net.ssl.SSLHandshakeException: Couldn't find

Email

请教各位，我在使用JSSE的时，为什么总是出现ssl.SSLHandshakeException？？
代码如下，每次执行到out.flush()的时候就会出现该异常？
还有，我在执行完了factory.createSocket后执行
socket.startHandshake();也会出现该异常？
请问有什么办法怎么解决？
急！！！请尽快答复！！！
先行谢过啦！！
代码
SocketFactory factory = SSLSocketFactory.getDefault();
Socket socket = factory.createSocket(argv[0], HTTPS_PORT);
//socket.startHandshake();
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
out.write("GET / HTTP/1.0\r\n\r\n";
out.flush();
String line;
StringBuffer sb = new StringBuffer();
while((line = in.readLine()) != null) {
sb.append(line);
}
out.close();
in.close();
