JOC Cockpit - Troubleshooting - Installer raises error "Validating data for panel jetty was not successful"

Observations

A user tries to install JOC Cockpit, but gets an error as below:

[scheduler@jos11rc2 joc.1.11.0-RC2]$ ./setup.sh -u joc_install.xml
java -Dizpack.mode=privileged -jar "./joc.1.11.0-RC2.jar" joc_install.xml

Explanations

By using the -u switch the user requested the installer not to switch to the root account in order to acquire privileges that allow to create folders. At the same time the user scheduler does not have the permissions to create a folder in the /opt/sos-berlin.com directory.

Admittedly the error message that is presented by IZPack installer is confusing, however, missing permissions are the cause for this error.

Use ./setup.sh joc_install.xml without the -u switch to install JOC Cockpit with correct permissions.
