I run a dev geoserver 2.21 on the latest ubuntu LTS 22, which has apt packages for JDK17 and tomcat 9. The rendering engine is the builtin-JDK engine*, but apart from that, there are no problems related to JDK17.
So JDK17 is probably not your problem. In fact, javax.servlet should be provided by the glassfsh servlet engine, it is not a part of JDK17 but from JEE 10. Hans. *We know how to fix the renderer, we just didn't get around it. -----Original Message----- From: Mark Hammond <mark.hamm...@bto.org> Sent: maandag 1 augustus 2022 14:51 To: geoserver-users@lists.sourceforge.net Subject: [Geoserver-users] Geoserver 2.21.0 and JDK17 Hi Folks, Have been successfully using Geoserver for a number of years. Have been doing preparatory work to upgrade to JDK17/Glassfish 6.x Having noticed Geoserver 2.21.0 supports JDK17, downloaded this to try on the new setup. Geoserver 2.21.0 fails to deploy on a virgin JDK17/GF6.2.5 setup with the following error reported in the log: remote failure: Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.IllegalArgumentException: java.lang.NoClassDefFoundError: javax/servlet/ServletContextListener. Please see server.log for more details. This suggests some component within 2.21.0 has not been upgraded to JDK17 since it is still using the javax.servlet namespace. Tried with and without additional database drivers/plugins Are there separate JDK17 and non-JDK17 branches? If so, where can I get the JDK17 version from. If there are not separate branches. Can anyone suggest a set of steps that would see 2.21.0 deploy correctly?
