我正在使用Sakai 2.9.1，Tomcat 7.0.59，JDK 1.6，MySQL 5.5，Maven 3.0.5和Windows XP。 Sakai到Tomcat的构建已经成功，当我启动Tomcat时，我遇到了很多错误，并且Sakai没有加载。所有环境变量也已配置。

如果您查看您提到的网站上的Maven构建和部署（2.x - 3.x）页面，请参阅第4.0节（“安装Maven 3.0或更高版本”），并说明
（警告）Maven 3.0或更高版本是执行Sakai 2.9版本所必需的。
这可能是一个起点，因为在启动Tomcat时似乎无法找到类。 你尝试过使用Tomcat 7吗？ 你有没有正确配置Sakay？
