Tomcat 9 should work with Java 8. If you are having compilation issues please report them here. Tomcat 9 will continue to support Java 8 for its entire lifetime. The Servlet Specification that Tomcat 9 tracks (4.0) requires support for Java 8 and that will never change. At some point (no current plans anywhere on the horizon), Tomcat 9 will reach end-of-life and you will need to use a higher version of Java on newer versions of Tomcat. -chris - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

( https://access.redhat.com/solutions/6724981, subscription required) We did and it solved our problem.

Assistance with Apache Tomcat Integration with MS Sentinel
Good day, We are trying to integrate Tomcat Apache with Sentinel, so we just wanted to get some clarity on a few things. We installed Apache Tomcat data connector on Sentinel. It seems the Apache servers in our environment are running on Windows machines, so when we download and install the windows agent on the Apache Tomcat servers, will the logs go through our syslog server via AMA or through our syslog server via CEF? It seems the version of Apache Tomcat currently being run in the environment is Apache Tomcat/9.0.85, is it compatible with the Deprecated Apache Tomcat data connector on MS Sentinel, which was developed using Apache Tomcat version 10.0.4?
