I am getting this error on Tomcat 9. I have been searching for problems in the internet to fix this but none seems to solve the problem.

What should I do here, I have tried adding different dependencies to check if the problem is going to be resolved. I have also tried restarting the server and my laptop as well, I also tried reinstalling tomcat.

  • Are you deploying JSF application? – seenukarthi Sep 28 '21 at 05:11
  • Yes I'm trying to deploy a JSF application, Tomcat worked earlier and suddenly showed this problem. – Keiyonkun Sep 28 '21 at 05:23
  • This `Caused by: java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener` looks pretty clear to me. You are using JSF but there is nothing JSF related in your dependencies (and no the `javaee-web-api` doesn't count as that is only an API and it is a borked version as well). – M. Deinum Sep 28 '21 at 05:29

    I think you need to upgrade to JavaEE 8 because Tomcat 9.0 is a servlet 4.0 container which supports JavaEE 8 (currently you are using JavaEE 6). Also, like @M.Deinum said, you need to add JSF dependency. – Kedar Joshi Sep 28 '21 at 05:35
  • @KedarJoshi: if you are referring to the `java-web-api` dependency, it should rather be removed since Tomcat is not a Java EE Web Profile server. One might have the wrong impression that adding all Java EE APIs (including JSF) will automatically add their implementations. – Piotr P. Karwasz Sep 28 '21 at 15:33
  • @PiotrP.Karwasz Not to remove `java-web-api` make it as `provided` scope. – seenukarthi Sep 29 '21 at 04:39
  • @KarthikeyanVaithilingam: the [Java/Jakarta EE Web Profile](https://stackoverflow.com/q/24239978/11748454) contains around 20 specifications. Tomcat provides the implementation of [5 of them](https://tomcat.apache.org/whichversion.html). – Piotr P. Karwasz Sep 29 '21 at 05:24
