OpenCMS部署时容易出如下错误(OpenCms is not properly initialized!)

1.OpenCMS部署时容易出如下错误(OpenCms is not properly initialized!)

http://localhost:8080/opencms/setup/step_8_import_modules.jsp

HTTP Status 500
OpenCms is not properly initialized!
Please make sure that the OpenCms setup wizard has been run once and is disabled now.

解决方案：

尝试删除tomcat下work文件夹下的内容然后重新访问setup，产生的原因是如果以前安装过opencms版本在相同的Servlet Container中，可以能会产生上面的错误。

try to delete the contents of the tomcat work folder and run the setup again. This kind of error can occur, if you had a previous opencms version installed in the same servlet container.
