Hello, I decided to upgrade our Fuseki 3.17.0 running on Tomcat 9 to the latest version released yesterday (thank you, Andy, for your hard work and a late night release!). I ran into the “java.lang.NoClassDefFoundError: org/apache/logging/log4j/Logger” exception. The closest issue I found was https://stackoverflow.com/questions/20909446/caused-by-java-lang-noclassdeffounderror-org-apache-log4j-logger but I don’t think Fuseki WAR file has these problems.
I am able to start the newest Fuseki server in the standalone mode without problems: FUSEKI_BASE=/etc/fuseki sudo /opt/apache-jena-fuseki-4.3.1/fuseki-server 21:57:56 INFO Server :: Apache Jena Fuseki 4.3.1 21:57:56 INFO Config :: FUSEKI_HOME=/opt/apache-jena-fuseki-4.3.1 21:57:56 INFO Config :: FUSEKI_BASE=/etc/fuseki 21:57:56 INFO Config :: Shiro file: file:///etc/fuseki/shiro.ini 21:57:56 INFO Config :: Load configuration: file:///etc/fuseki/configuration/a.ttl ... 21:57:57 INFO Config :: Load configuration: file:///etc/fuseki/configuration/z.ttl 21:57:57 INFO Server :: Configuration file: /etc/fuseki/config.ttl 21:57:57 INFO Server :: Path = /a ... 21:57:57 INFO Server :: Path = /z 21:57:57 INFO Server :: System 21:57:57 INFO Server :: Memory: 4.0 GiB 21:57:57 INFO Server :: Java: 11.0.11 21:57:57 INFO Server :: OS: Linux 5.4.0-91-generic amd64 21:57:57 INFO Server :: PID: 245617 21:57:58 INFO Server :: Started 2021/12/13 21:57:58 CET on port 3030 The Tomcat server is quite a vanilla tomcat9 package installation under Ubuntu 20.04 LTS. Do you have an idea where I should look at next? I checked out https://jena.apache.org/documentation/fuseki2/fuseki-webapp.html#fuseki-with-tomcat9-and-systemd and already have the systemd edits suggested. Thank you in advance!
