我已经按照以下IBM Social Business Toolkit SDK Development Environment Setup Youtube 视频中的描述设置了 Java EE Eclipse ，我在IBM SBTSDK 的 OpenNTF.org 页面上找到了该视频。IBM Social Business Toolkit SDK 开发环境设置
当我启动 Tomcat 并打开 sbt.sample.web 并调用其中一个示例时，我在 Tomcat 日志中收到以下错误（见下文）。
我使用以下版本的 SBTSDK sbtsdk-1.0.0.20130228-2321。
以下项目在我的工作区中也有错误，无法构建描述资源路径位置类型项目“com.ibm.sbt.bootstrap211”缺少所需的源文件夹：“src”com.ibm.sbt.bootstrap211 构建路径构建路径问题
任何想法出了什么问题？
