java - CAS overlay with CAS Management overlay error

Question

I have installed tomcat-9.0.41 I build cas-overlay-template 6.3 and placed the cas.war in the webapps started the server, everything works as it should.

I then build the cas-management-overlay 6.3 placed the cas-management.war in webapps but when I restart tomcat I get the following error when tomcat tries to load

firstly I dont understand what the exact problem is and how am I supposed to correct this "classpath" that the action is talking about.

any help would be appreciated!

Answer 1

I downloaded the latest versions, reinstalled everything into two different tomcat servers with different domains. Which was not needed after all

I used as suggested

./gradlew clean copyCasConfiguration build

The error persisted. So I took the jar files from the cas installation in

/opt/cas/apache-tomcat-9.0.41/cas/ROOT/WEB-INF/lib/jackson-* 

and coppied them into

/opt/casmgmt/apache-tomcat-9.0.41/casmgmt/ROOT/WEB-INF/lib/

and the casmgmt server server app started successfully. apparently the people who wrote the source of the overlays either they don't have enough documentation as to what libs and versions should be used and when, or they have some sort of misconfigurations as to what the dependencies are and all
