I have the REGION table:

Code:

REG {
    id number,
    dateCreation Date
  }

I have a LOCALE table:

Code:

LOCALE {
     locale String
  }

I have a REGION_DESCRIPTION table:

Code:

REGION_DESCRIPTION {
     locale String,
     regId number,
     description
  }

REGION_DESCRIPTION has a composite key: locale is a foreign key pointing to the LOCALE table. And regId points to the REGION table.

I would like to map this to my Region java class:

Code:

private List<RegionDescription> descriptions;

I tried different approache in JPA. But I cannot get the mapping to work. Any suggestions?
