I'm having this issue as well, using JPA 2 / Hibernate 4.1.4.Final on an Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production database.

I'm using a legacy database schema and sequences, and need to access tables and sequences on a schema that is different from the default schema used in other mappings. Using public synonyms is not allowed, all database object names have to be prefixed by the respective schema name.

Since this issue is quite old already, will it still be resolved now that it occurs in a recent version of Hibernate? Or is there another solution?
