Technical questions
Why does the default OpenCms url contain /opencms/opencms/?
The first /opencms/ is the folder of your OpenCms installation in the webapps folder of your servlet container (tomcat,jboss,etc.). The second is a servlet mapping to the main OpenCms servlet which handles the requests. You can install OpenCms as root-application of you servlet container to get rid of the first /opencms/. During the installation process you can rename the servlet mapping (for example to cms) to shorten the second /opencms/.Alternatively there is a guide how to get rid of /opencms/opencms/ shipped with the alcacon documentation. See also Removing /opencms/opencms from site url
My OpenCms upgrade fails, what are common pitfalls?
A common pitfall is that your Servlet container(Tomcat,JBoss,etc.) has no write access to the OpenCms installation, check the permission and give the servlet-container write access.
Another pitfall is that the upgrade wizard is not able to open a display, which can be fixed by starting the servlet container with the following java arguments:
-Djava.awt.headless=true
User Management
What is the difference between webusers and normal users?
The webusers are not allowed to login into the OpenCms workplace. You can use them to create a restricted area on your homepage. There is a howto how to create a restricted area on your homepage: How to create a restricted area on your homepage.
I lost the password of the user "Admin", what can I do?
If you have database access you can reset it with the following SQL query:
UPDATE CMS_USERS SET USER_PASSWORD='ISMvKXpXpadDiUoOSoAfww==' WHERE USER_NAME='Admin';
This sets the "Admin" password to 'admin'. NOTE: Use this at your own risk!
I want to deny the "Users" group access to a certain folder, how?
When you try to change the permission of certain folder to deny the "Users" access to a certain folder you see that this this group is not editable. The trick is to add the "Users" group again to get the possibility to change the groups permission.
