向https端发送报文出错，源代码都研究好几天了无果，求救

PostMethod mypost = new PostMethod();

mypost.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");

 mypost.addParameter("reqData", getrevFromBASE64(body.getBytes()));//请根据实际修改上送包xml数据

 HttpClient client = new HttpClient();

 client.getParams().makeStrict(); //此句必需

 client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "GBK");

Protocol myhttps = new Protocol("https", new AuthSSLProtocolSocketFactory(null, null, new URL("file:" + i.getTruststore()), null), 443);

client.getHostConfiguration().setHost(i.getIp(), Integer.parseInt(i.getPort()), myhttps);

 int re_code = client.executeMethod(mypost);

结果在调用client.executeMethod(mypost);方法时报错，异常很诡异，和用

HttpConnection myconn = new HttpConnection(i.getIp(), Integer.parseInt(i.getPort()), myhttps);

myconn.open();

mypost.execute(new HttpState(), myconn);

报错是一样的，都是因为在at org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:707)这个位置调用open方法出错，而且也不是网络的错误信息，异常如下：
