java.lang.ClassNotFoundException - problem with clustering
Hello there,
although Infinispan is great tool, I have problem with clustering mode. Your help would be very useful.
Problem: when I setup Infinispan to be able to work in clustering mode (config contents below) I had error "NotSerializableException" in some classes, so I made changes in code (now classes implements Serializable). After that changes I receive error java.lang.ClassNotFoundException. Why?
Config contents:
