Dear all, I am trying to get the fuseki triple store to work for the first time. I have it running via tomcat on localhost:8080/fuseki However, if I type any dataset name, select in-memory (or any other option), I just get the result
"Sorry, that didn't work because: error" Without any further indication. Is there a way to make this more verbose? I could not find any more detailed error message in any logs (but I might look in the wrong place). Here is my setup: Debian 10.8, Tomcat 9.0.5.2 I deployed the Fuseki 4.1.0 .war-File which worked great. /etc/fuseki is owned by the tomcat user. I tried to follow these directions: https://jena.apache.org/documentation/fuseki2/fuseki-webapp.html#fuseki-web-application I don't quite understand the "configuring logging" section. My path is /opt/tomcat/webapps/fuseki/log4j2.properties The file is there. When the logging goes to the standard output, this would mean that the error message should be displayed in the browser, right? Also the next paragraph "Fuseki with Tomcat9 and systemd" is confusing: I have a path /etc/systemd/system with a file tomcat.service I edited this file and added # Allow access to the Fuseki area ReadWritePaths=/etc/fuseki/ StandardOutput=file:/opt/tomcat/logs/catalina.out But this does not solve the problem. There is still nor warning or error message ini Catalina.out 10-Sep-2021 10:46:11.229 INFO [main] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
