Can you clarify your use-case? Are you attempting to use Apache Cassandra as the storage mechanism for ActiveMQ Classic? If so, you'll need to implement a Cassandra-based persistence adapter since it doesn't provide a JDBC driver or other means of integration. It's possible such an adapter already exists, but the best information I could find [1] references a defunct project [2] that hasn't been updated in 15 years.
If you're simply trying to start an instance of Cassandra via Spring and use it from your application along with ActiveMQ Classic I think the Cassandra community would be a better resource for you. I don't see anything directly related to ActiveMQ in your question.
