Hi, I have a problem.

I created an application in Scout 23. When I try to deploy it to Tomcat on Windows, it reports an error:

26-Feb-2024 20:14:51.732 SEVERE [http-nio-8030-exec-12] org.apache.catalina.core.StandardContext.listenerStart Skipped installing application listeners due to previous error(s)


Tomcat was installed by someone else. I assume that not all important things are installed on the computer, but unfortunately I have no idea what is missing and what is causing this error. (On my computer with Eclipse, the application works fine.)

Note: I created a clean application "HelloScout" and it can't be deployed in this environment either. The error is the same, so the problem is not in the application itself, but in the system configuration.

Other informations:
Scout version: 23.2.15 (Java execution environment JavaSE-17)
Windows version: Windows Server 2012 R2 (yes, I know it's an old system, but it's a customer's system and I have no way to change it).
Java version: 
>java -version
java version "11.0.21" 2023-10-17 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.21+9-LTS-193)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.21+9-LTS-193, mixed mode)


Can someone please advise me what to install to make it work?
Thank you very much in advance for any advice.

Do you know the Tomcat version you are using? Tomcat 10?

Between Tomcat 9 and Tomcat 10 there is a breaking change as the javax.* classes/interfaces are now available at jakarta.* - see https://tomcat.apache.org/migration-10.html

According to the link above there may also be an automatic migration if you place the web application in your webapps-javaee folder - however I have never tested this.

With Scout 24.1 we are also using the newer jakarta package prefixes.

It's Tomcat 10.1.
Would a downgrade to Tomcat 9 help?

Downgrade to Tomcat 9 should resolve this error.
