jdk1.7  tomcat7  mysql5.0 按照“ JEECMS-V2012导入eclipse步骤说明”  的步骤导入，但运行是出错 之前已经用程序包安装，成功。但源码就是运行不了 以为系两种方法有冲突，故把jeecms的ROOT文件夹删掉，用回tomcat7的默认的ROOT文件夹，再次运行，同样不行 请问怎么解决啊 好苦恼啊

请说明你的操作过程

就是按哪些步骤导入了，
然后在tomcat7运行，另外的一些程序能正常运行，这已经就不跟tomcat7的问题了，然后我输入http://localhost:8080/jeecms/   就出现上图，500错误。

我用的是myeclipse 8.5

请详细说明你的操作过程

一、 首先打开源码包jeecms-2012-src.zip
二、新建一个工程，如jeecms
三、将src文件夹复制放到myeclipse下的src文件夹中，选择编码为UTF-8
四、将安装包的ROOT，导入myeclipse中的WebRoot
五、增删jar包

六、导入数据库，数据库文件在ROOT/install/db下。您也可以使用安装版帮您导入的数据库
   （唯独这个不知怎么做，我用安装版安装已经成功，数据库还要导入吗？）


七、修改jdbc链接，文件在WEB-INF/config下的jdbc.properties
八、将install/config下的web.xml复制出来覆盖掉WEB-INF下的web.xml

九、启动
前台路径为http://localhost:8080/jeecms 出现上诉图错误

myeclipse把WEB-INF/classes下的4个配置文件放到src下
