我想运行一个cyc（opencyc）Java类，但是当我运行此类时，出现错误消息，提示网络不可达。我正在使用NetBeans 7.0和opencyc 2.0 win 32版本。我正在使用localhost（127.0.0.1）进行测试。错误如下。

为什么会这样呢？我如何连接到cyc？
最佳答案
如果您使用的版本与我相同，则它会尝试使用以下名称定义的主机名和端口建立与Cyc映像的连接：
CycConnection.DEFAULT_HOSTNAME
CycConnection.DEFAULT_BASE_PORT
您可以通过在Cyc映像中评估以下内容来找到要使用的正确值：
（获取机器名称）
*基础TCP端口*
希望这对您有用。
