Tomcat7 无法启动 sakai 2.9.1。我目前正在使用Windows xp，tomcat 7.0.59，maven 3和java 1.6。startup_err日志文件（手动创建）出现以下错误。需要一些帮助。谢谢。

正如日志所说，它无法加载org/sakaiproject/lessonbuildertool/simplepageitem.hbm.xml
检查它是否存在并具有正确的结构。
我在 Linux 上安装 Sakai 2.9.3 时遇到了同样的问题（所以它可能毕竟不是同一个问题）。 此消息表明原因是多个类装入器正在装入某些jar文件。 事实上，我发现我的Tomcat 7试图加载Sakai附带的commons—dbcp—1.2.2.jar，但也/usr/share/tomcat7/lib/commons—dbcp.jar 。 我将两者中的一个移开了，但是在我从Java 1.6切换到Java 7之后，错误才消失（根据我的安装日志）。 您可以在Tomcat的conf/catalina.properties中配置哪些jar文件将由哪些类加载器加载，但是Sakai的文档在这一点上对我来说具有很高的巫毒因子。
