Re: [Exist-development] betterform-config.xml update for log4j2?

[Chris T. <chr...@gm...>]

I notice that:

        <Property name="logs">${web:rootDir}/WEB-INF/logs</Property>

works sensibly when eXist-db is run via war file within Tomcat 8; however, when I simply run via:

    ./bin/startup.sh

just after ./build.sh all, then the logs end up in:

    ${web:rootDir}/logs/exist.log

so it appears that the substitution is at least occurring within the Tomcat container. I haven’t tested the analogous configuration with jetty so I don’t know if the problem is peculiar to jetty or to the way that eXist-db is running “standalone”.

ciao,
Chris
