Question

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

我还将它与弹出窗口结合起来，这个窗口基本上是允许用户通过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中构建此项目时，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

以下是先前发生的错误列表，通过转到项目首选项 - ＆gt;验证 - ＆gt;消除了这些错误。禁用XML验证。（这些是原始问题的一部分 - 我已经更新了这个问题，因为我自己解决了以下错误导致的问题......）

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代码。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，或通过嵌入式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g按钮即可。单击其箭头标记，然后选择GWT Compile Project选项。最后，在成功编译到服务器的服务目录之后，只需复制项目的war目录。对于后者，右键单击项目并选择Run / Debug As - ＆gt; Web应用程序选项。然后，您将获得一个链接，您可以在浏览器中复制粘贴并测试您的应用程序。
