通过httpclient向服务器发送https请求，可是连接报错。

 // 构造HttpClient的实例
    HttpClient httpClient = new HttpClient();
    GetMethod getMethod = new GetMethod(ssoInterfactUrl);
    // 设置连接超时和读取超时
    httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(30000);
    httpClient.getHttpConnectionManager().getParams().setSoTimeout(30000);
    try {
        WmsvrUtils.log("start");
        int statusCode = httpClient.executeMethod(getMethod);
        WmsvrUtils.log("statusCode" + statusCode);
        if (statusCode != HttpStatus.SC_OK) {
            WmsvrUtils.log("Method failed:"  + getMethod.getStatusLine());
        }
        byte[] responseBody = getMethod.getResponseBody();
        ssoVerifyString = new String(responseBody);
    } catch (HttpException e) {
        WmsvrUtils.log("[zjgfsso] Please check your provided http address!", e);
    } catch (IOException e) {
        WmsvrUtils.log("[zjgfsso] network error", e);
    } finally {
        // 释放连接
        getMethod.releaseConnection();
    }

按@红薯的建议增加了超时，报错如下：

服务器端到底在干什么……

好伤心啊，我们是客户端，通过webservice传递请求，可是试了两种完全不同的实现，都是read time out。问他们服务器的负责人，他们说服务器没有日志…… webservice地址是https的，证书我已经加了。通过浏览器可以打开https连接，telnet 80 和 443端口都是通的。

对网络不了解了……
