More info:
By putting some System.out messages in the BasetAcl.java code, I have
narrowed it down. I am gagging on the command:
dbCon = BasePeer.beginTransaction(dbName);
I have verified that the dbName parameter is correctly set to "ndb_test". Is
the fact that this method is called beginTransaction and the log message ~
"connected to a database that does not support transactions" indication of
my problem? Postgres supports transactions, right? Does this mean I have
incorrect connection parameters?
I have:
services.DatabaseService.database.default=default
services.DatabaseService.database.default.driver=org.postgresql.Driver
services.DatabaseService.database.default.url=jdbc:postgresql://localhost/nd
b_test
services.DatabaseService.database.default.username=username
# I have not yet set a password until I get things working
services.DatabaseService.database.default.password=
then
services.DatabaseService.database.adapter=DBPostgres
services.DatabaseService.database.adapter.DBPostgres=org.postgresql.Driver
Is this not right? I'm afraid I am stuck at this point. :/
Thanks for any assistance!
Steve B.
