Where can I find the error log of jasper server community?

[gustavofarias]

Whener a try to remove a particular user form the server, I get the message: 
There was an error on the server. Try again or contact site administrators. (Error UID: 23cea5f8-9573-4328-87c2-d87e6a9d7126)

In var/log/tomcat9, I can't find any log produced by jasper server. In other forums or answers there are some indications of where the logs could be, but I couldn't find them in any of the locations, like  WEB-INF/logs.

I'm using Jasper server community 7.8 on ubuntu 18, in a package managed tomcat 9.

First I needed to activate the logs.

in

/var/lib/tomcat/webapps/jasperserver/WEB-INF/log4j2.properties[/code]

change this:

appender.fileout.fileName=${log4j:configParentLocation}/logs/jasperserver.logappender.fileout.filePattern=${log4j:configParentLocation}/logs/jasperserver.%i.log.gz[/code]

to something like:

appender.fileout.fileName=/var/log/tomcat/jasperserver.logappender.fileout.filePattern=/var/log/tomcat/jasperserver.%i.log.gz[/code]
