>> java.net.ConnectException: Connection refused (Connection refused)
This is the script trying to stop an earlier instance of Tomcat and not finding any; which is expected.
>> java.lang.UnsupportedClassVersionError: org/epics/archiverappliance/config/ArchServletContextListener has been compiled by a more recent version of the Java Runtime (class file version 56.0), this version of the Java Runtime only recognizes class file versions
up to 52.0 (unable to load class
This is an incompatible java version; the JDK you are using is older that what the EPICS archiver appliance distribution was compiled with. Do a "java -version" to check what version you have. Perhaps you can try to use the most recent JDK; most VM's are usually
backwards compatible.
