Hello Everyone,

I setup a quick and dirty cluster following

https://tomcat.apache.org/tomcat-9.0-doc/cluster-howto.html

I am seeing the following:
12-Apr-2023 19:18:00.369 WARNING [main]
org.apache.catalina.ha.tcp.SimpleTcpCluster.registerManager Manager
[PersistentManager[StandardEngine[Catalina].StandardHost[localhost].StandardContext[/esolutions]]]
does not implement ClusterManager, addition to cluster has been aborted.

You have an Context (web application deployed at /esolutions) with an explicit Manager configured. If you do that, it needs to implement ClusterManager else the Context can't be clustered.

Contexts that don't have an explicit manager configured get a cluster defined default if clustering is enabled and the StandardManager if clustering is not enabled.

And

12-Apr-2023 19:17:52.652 SEVERE [main]
org.apache.catalina.ha.deploy.FarmWarDeployer.start FarmWarDeployer can
only work as host cluster subelement!

You added the cluster at the engine level so you can't use the FarmWarDeployer. You need to remove that section - or move the Cluster definition to inside the Host.

Mark
