我已经下载了Jsoup jar并将其添加到库中.我在Eclipse中添加了代理设置.但是当我在代码中尝试这个时:

Document doc = Jsoup.connect("http://www.wikipedia.com").get();

任何人都可以帮我找出解决方案吗？是否有一种特定的方式来设置代理(如果我遗漏了什么).附上相同的截图.任何帮助/指导将受到高度赞赏.

我是Neo4J概念的新手.我想知道,如果有任何方法,列出以graphdb格式部署后连接到特定节点的所有可能节点.简单地说,我已经能够导入一个分隔的.cv文件 .现在我想知道是否可以列出任何特定节点的所有邻居,其id可以作为参数传递.

我已经成功安装并启动了CDH5,当我尝试通过Hue运行一个简单的WordCount示例时,我面临以下错误.
