[tjdghk]

现在有一个打印账票的处理，如下，
但是一执行就会出现如下错误。
SvfrClient svf = new SvfrClient(hostName);

错误：

[tjdghk]

有没有人遇到过同样的问题的，

求告人赐教这个问题出现在那里？ 原因是什么？

[meihuiyu]

导入包？

[tjdghk]

包已经导入，而且上个星期为止正常，
回不回是hostName 跟IP有关系？ 它被占用？

[meihuiyu]

ip不对

[bsr1983]

因为没有代码，按常理推断可能是由于服务器没有启动，或者是防火墙等原因
必须先运行服务器再运行客户端，次序不能颠倒，也就是必须先有接收的，再有发送的，不然发送的地方没有接收的，肯定会出Connection refused: connect 之类的错误

[一洽客服系统]

对方拒绝连接 检查下服务器名字或是IP是否正确

[tjdghk]

问题解决了
首先检查了ip，没问题，
服务器正常，
最后没办法，把以前的jar文件更新了一下，
问题解决，可能那个没有正常启动
