TreeCacheAop and JDBC Persistance and NotSerializableExcepti
I get java.io.NotSerializableException when using the JDBC Cache loader to persist to JDBC backend.
I was under the impression that with TreeCacheAop and aspectizing, there is no need to Serialize my cache business objects.
could someone shed some light on this or point me to specific section in docs for this ?
