Solutions

1. Specify the sequence name explicitly in the @SequenceGenerator/@GeneratedValue mapping for that table.

When it happens

Trigger: Thrown when Hibernate cannot derive a sequence name for a table-based id generator.

Common situations: Typical situations: missing sequenceName/table configuration on the generator; per-table generator without naming information.
