smartgwt 初学者 - 尝试使用 Smart GWT 编译项目时出错

Question

我已按照 http://www.javacodegeeks 中的说明进行操作.com/2011/01/advanced-smartgwt-tutorial-part-1.html 并尝试创建一个使用 Smart GWT 的简单屏幕。

我还将其与弹出窗口结合起来，该窗口基本上允许用户通过 Oauth 登录 - 它是通过浏览器主窗口中的一行代码调用的。

当我尝试在 Eclipse 中构建这个项目时，我收到以下错误 ---

更新 ---

 Internal validation error               java.lang.ArrayIndexOutOfBoundsException
ISC_DataBinding.js  /Spark Crawler/WebContent/com.google.api.gwt.oauth2.script.OAuth2Script/sc/modules  line 0  JavaScript Problem

下面给出了之前发生的错误列表，这些错误通过转到项目首选项 -> 验证 -> 已消除。禁用 XML 验证。 （这些是原始问题的一部分 - 现在我已经更新了这个问题，因为我自己解决了由于以下错误而导致的问题......）

我在这里做错了什么？

Answer 1

确保您将代码编译为 GWT 应用程序，而不是纯 Java 应用程序。为此，您有两种选择。编译您的应用程序并使用外部 Web 服务器，或者通过嵌入到 Eclipse Jetty Web 服务器运行/调试您的应用程序。对于前者，只需查看工具栏并找到蓝色的 g 按钮即可。单击其箭头标记并选择 GWT 编译项目选项。最后，编译成功后，只需将项目的war目录复制到服务器的service目录即可。对于后者，右键单击项目并选择 Run/Debug As -> Web 应用程序选项。然后，您将获得一个链接，您可以将其复制粘贴到浏览器中并测试您的应用程序。
