From googles, it seems like a few people have had this problem before. I am getting an exception thrown on trying to persist an entity which has an ID with a GeneratedValue strategy of GenerationType.IDENTITY. (I was able to persist a test entity having the same fields, except for the ID). The error returned is:

ERROR: JZ0SJ: Metadata accessor information was not found on this database. Please install the required tables as mentioned in the jConnect documentation.

I tried the suggested fix which was to run the JConnect script sql_server15.0.sql but it didn't help.

Any suggestions on how to fix this one?

The full stack trace:

ERROR: JZ0SJ: Metadata accessor information was not found on this database. Please install the required tables as mentioned in the jConnect documentation.
