Question

我编写了一个java文件，该文件打开与服务器的HTTPS连接，该服务器已授予从我们的unix服务器调用其Web服务的限制访问权限。所以我们能够ping服务器ip，用端口443 telnet服务器ip都成功，所以网络团队确认我们可以开始调用webservices。现在我们已经尝试了Windows服务器上的所有内容，安装了他们在本地文件夹中提供的证书，只需运行jar。我们能够建立联系。现在我们必须迁移到unix服务器。我们已经将jar的本地证书复制了。在运行jar时，我们得到以下异常。

不知道遗失了什么。

此致 Rache

通过在我的主机文件中添加以下条目解决了该问题。（在Linux和Unix文件中将在/etc/hosts下）

<ip address>       wugateway2pi.westernunion.net

这很有用。

java.net.UnknownHostException：url
