Following the instructions for deploying camunda war file to plain tomcat running under OpenJDK11 fails due to the fact that JAXB is no longer available in JDK 11. I was able to fix by adding JAXB files to the lib directory in the war file, but you should probably consider adding them to the war distribution.
There were previous threads on this but none of the answers there were acceptable or appropriate:
- Downgrade Java to Java 9
- Use Oracle JDK
- Add dependency to the pom file (I have no pom file as I am installing a war)
