smartgwt初学者 - 尝试使用智能GWT编译项目时发生错误

Question

我按照http://www.javacodegeeks.com/2011/01/advanced-smartgwt-tutorial-part-1.html的说明操作，试图创建一个使用智能GWT的简单屏幕。

我还将它与一个基本上允许用户通过Oauth登录的弹出窗口结合使用 - 它是从浏览器的主窗口调用一行代码。

当我尝试建立在Eclipse这个项目，我收到以下错误---

UPDATE--

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 

下面给出的是先前发生的错误的列表，这些通过转到项目首选项 - >验证 - >禁用XML验证来消除。 （这些都是原来的question-我现在已经更新了这个问题的一部分，我已经解决了这个问题，是由于下面的错误，我自己...）

什么我错在这里做什么？

Answer 1

确保您将代码编译为GWT应用程序，而不是纯Java版本。要做到这一点，你有两个选择。编译您的应用程序并使用外部Web服务器，或通过嵌入Eclipse Jetty Web服务器运行/调试您的应用程序。对于前者，只需看看你的工具栏并找到一个蓝色的g按钮。点击它的箭头标记并选择GWT编译项目选项。最后，在成功编译到服务器的服务目录之后，复制项目的war目录。对于后者，右键单击该项目并选择运行/调试为 - > 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。
