Question

我无法在Mac上运行topcoder竞技场..

当我尝试从safari登录topcoder时，它说Java找不到。

所以我下载.jnlp ....但仍然无法运行

这是我的Java版本：

java -version
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-11M3527)
Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02-402, mixed mode)

以下是从我的Mac Air运行.jnlp时的错误消息：

此外，我的safari肯定已经开启了Java ...

Answer 1

该错误消息并不表示您找不到Java - 它是ConnectionTimedOut，它表示您可能被防火墙阻止，或者topcoder上的服务器以某种方式被清除。
