Thank you, Ivan, Latest version of the IPT cannot run on Tomcat 10. Max supported Tomcat is 9.

My environment uses Tomcat 10 (10.1.40) and JVM 21.0.9. When I try to access the application at http://ib.komisc.ru:8088/ipt/, I get a "404 The requested resource [/ipt/] is not available" error. The localhost.log file shows the following SEVERE errors during startup: text SEVERE [main] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class [org.gbif.ipt.config.IPTContextListener] SEVERE [main] org.apache.catalina.core.StandardContext.listenerStart Skipped installing application listeners due to previous error(s) The full log files are attached. I suspect the issue might be related to compatibility between IPT 3.1.7 and Tomcat 10 / JVM 21. Could you please confirm if this version of the IPT is supported in this environment? Any help would be greatly appreciated.
