Something seems to be wrong with your installation:

java.io.FileNotFoundException: /home/openemm/tomcat9/conf/server.xml (No such file or directory)

[Manoj Sreepada]

What can we do?

java.io.FileNotFoundException: /home/openemm/tomcat9/conf/server.xml (No such file or directory)

Thanks, Please Advice for any help.

Maybe a symlink is missing? You could compare your installation to the installation in the OVA file for missing directories, files or symlinks.

We get the following error:

Catalina.out log:

27-Aug-2020 11:48:20.927 INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: [/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib]

[maschoff]

This is not an error, just for INFO.

Hello,

we get the following error:

DB Connection cannot be established. (Maybe DB user or DB connection parameters for OpenEMM were not configured)
DB structure does not exist. (Maybe OpenEMM is not installed)

Thanks,
