Hi,

I'm using djigzo 4.6 with postgresql on an fully patched CentOS 7.8  
When I try to change the installed certificate for the webadmin-frontend, I get the following messages:

There was an error uploading the PKCS#12 file. Cause: Cannot run program "/usr/share/tomcat/scripts/execute-script-no-root.sh": error=2, No such file or directory

Problem is, there is no "scripts"-folder under /usr/share/tomcat/ .

How do I resolve the problem ?

Any suggestions are welcome

Best regards

fatcharly

The most likely reason this happens is that djigzo.home parameter is not  
set for Tomcat.

check whether /etc/sysconfig/tomcat contains the following line:

JAVA\_OPTS="-Ddjigzo-web.home=/usr/share/djigzo-web  
-Ddjigzo.home=/usr/share/djigzo -Djava.awt.headless=true -Xmx128M  
-Djdk.tls.ephemeralDHKeySize=2048"

Note: djigzo.home should point to the directory where the back-end is  
installed

If this is not configured, you can configure this with the following  
commmand (copied from  
[RedHat/CentOS — CipherMail Documentation](https://www.ciphermail.com/documentation/installguide/pages/redhat-centos.html)):

echo "JAVA\_OPTS=\"-Ddjigzo-web.home=/usr/share/djigzo-web \  
-Ddjigzo.home=/usr/share/djigzo \  
-Djava.awt.headless=true -Xmx128M\"" \>\> /etc/sysconfig/tomcat

Then restart Tomcat

Kind regards,
