尝试访问 IIS 上的 .NET WCF Web 服务时发生 Java 套接字异常

Question

当我调用服务的方法时，发生了 Web 服务异常，但我暂时无法弄清楚。

问题是这样的，我正在使用 WCF 编写的 Web 服务针对 IIS 7.0 运行 NetBeans 6.8:

如何解决？

Answer 1

“连接重置”通常意味着您和服务器之间的某人/某物正在重置连接或以某种方式阻止它。检查您是否可以正确连接到该端口上的服务器，没有任何问题，并且没有防火墙阻碍。

可以连接到相关端口的一个非常简单的测试是使用 telnet serverhostname portnum 远程登录到该端口，例如 telnet stackoverflow.com 80。
