Question

我正在关注StockWatcher app的步骤。在Eclipse中运行应用程序后，我得到一个显示以下内容的URL（http://127.0.0.1:8888/StockWatcher.html?gwt.codesvr=127.0.0.1:9997）：

我在字段中插入了我的名字，但是我收到了这个错误：

尝试联系服务器时发生错误。请检查您的网络连接，然后重试。

我在Eclipse中获得了这个输出：

我正在本地运行apache2。

有什么想法吗？

Answer 1

我遇到了与Eclipse相同的问题，并启动了一个新的WebApplication。我通过打开项目属性，java编译器，检查启用项目特定设置和使用的编译器合规性级别1.6来解决它它还给了我一条消息，我需要加载1.6 JRE。您还可以在项目属性，java构建路径，“库”选项卡，编辑JRE系统库中找到它，并确保在默认设置中使用JRE6，或者您可以添加它并选择它以供使用。

Answer 2
