There should be the following MBean available when starting ISPN server:
However, this MBean is not exposed and so the server-side serialization context cannot be configured.
More information about the MBean and its usage can be found in HotRodQueryTest . In infinispan itself (non-server) the JMX domain would be different but in the server it should be jboss.infinispan
I'll attach a test for server-side.
