I'm using shell-1.0-b6.jar, so perhaps I do need a cvs version...
About my NeoTest code, if I either comment out all 7 lines of
transaction code or just the line with getReferenceNode I get this
error forever in the shell:
java.rmi.UnmarshalException: Error unmarshaling return; nested exception is:
java.lang.ClassNotFoundException:
org.neo4j.impl.core.NotFoundException (no security manager: RMI class
loader disabled)
... and this forever in the terminal running NeoTest:
Apr 27, 2008 11:54:01 PM org.neo4j.impl.core.NodeManager getNodeById
SEVERE: Persistence error while trying to get node #0 by id.
org.neo4j.impl.persistence.PersistenceException:
org.neo4j.impl.transaction.NotInTransactionException: No transaction
found for current thread
I don't know why. Again, my nodespace is ∅ so if there are some
assumptions made that there will acutally be something there, it is
not so.
