所以我正试图写我的第一个程序，从网上提取数据，因为这是一个金融程序，我决定使用（据称）简单易用的雅虎！财务api。我下载了api.jar文件，为了保存，我通过addexternaljars工具将它们全部导入eclipse。
问题是，每当我尝试运行它时，都会遇到一个socketexception：permission denied runtime错误。
我运行的代码非常基本：

Stock stock = YahooFinance.get("ORCL");

这一行代码应该可以从YahooFinance获得oracle（orcl）股票的价值。相反，它抛出异常。
我想尽一切办法：
1） 我禁用了防火墙2）我仔细检查了我的.jar导入3）我测试运行这一行作为一个单独的线程的一部分（一个绝望的，盲目的举动，但我达到了那个点）。
我已经用尽了我所能想到的所有可能的研究Angular ，到目前为止我所发现的就是：使用jsp发送电子邮件
这看起来是一个非常类似的问题，所以我尝试了建议的解决方案：在eclipse.ini文件中添加“-djava.net.preferipv4stack=true”行。似乎没有效果。
以防万一，我也将eclipse.ini文件的内容粘贴在这里，以防万一我把它放错了位置或其他什么：

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20140603-1326
-product
org.eclipse.epp.package.standard.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Djava.net.preferIPv4Stack=true
-Dosgi.requiredJavaVersion=1.7
-Xms40m
-Xmx512m

我现在没主意了。我只想知道为什么会抛出这个异常，以及我能做些什么来防止它。
提前谢谢。
