Question

我按照IBM Social Business Toolkit SDK Development Environment Setup Youtube video中的OpenNTF.org page of the IBM SBTSDK中所述设置了Java EE Eclipse。 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（参见下文）。

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'缺少必需的源文件夹：'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？
