java.net.SocketException: Connection reset 异常

String json = URLEncoder.encode(jsonStr, "UTF-8");
HttpClient httpclient = getClient(true);//设置代理服务器（方法如下）
postMethod = new PostMethod(_url + "company&dataType=companyData"); //传送的是json的数据连接
StringRequestEntity requestEntity = new StringRequestEntity(json);
postMethod.setRequestEntity(requestEntity);
int code = httpclient.executeMethod(postMethod);
//服务器代理方法
private HttpClient getClient(boolean flag) {
HttpClient client = new HttpClient();
if (flag) {// true
String proxyHost = "pc1111101";// 代理主机
Integer proxyPort = 8080;// 端口
client.getHostConfiguration().setProxy(proxyHost, proxyPort);
String userName = "abc";// 用户名
String password = "abc123";// 密码
Credentials defaultcreds = new UsernamePasswordCredentials(
userName, password);
client.getState().setProxyCredentials(AuthScope.ANY, defaultcreds);
}
return client;
}
当运行到这里的 int code = httpclient.executeMethod(postMethod); 时候就会出以下异常：java.net.SocketException: Connection reset

备注：我用的是commons-httpclient-3.1的包

控制台输入

telnet pc1111101 8080
如果进去的话表示服务成功了，否则失败。
楼主应该是地址写错了。pc1111101 换成ip 试试

我也觉得

我运行你的代码，结果如下：

程序等待服务器端输入数据并且输出，可见没有抛出你的错误。请检查你的防火墙是否允许这个9999端口进行通讯。

应该系你那个post被占用了，所以一直从新连接
