Dear all,
I have a setup as follows:
- Rocky Linux 9.3
- java-17-openjdk-17.0.10.0.7-2.el9.x86_64
- camunda-bpm-tomcat-7.20.0.zip installed in a directory
I want to use the functionalities of camunda-platform-7-mail, so I installed in the /lib directory:
a) jakarta.mail-api-2.1.2.jar
b) slf4j-api-2.0.11.jar (replacing the previous version)
c) angus-mail-2.0.2.jar
d) camunda-bpm-mail-core-7.20.0.jar
Starting the server I receive the following error:
org.apache.catalina.LifecycleException: Failed to start component [StandardServer[8005]]

If I remove the .jar, the server starts up again.
What I need to change to finally getting the tomcat running?
Thank you in advance for your help,
Giovanni
