java - Foreign key relationship in nested one-to-many -

i have these classes, unidirectional one-to-many relationship mappings below:

@entity public class databasedetailsvo {     @id     // primary key databasedetailsvo     private string databasename;      @onetomany     private list<tabledetailsvo>; }  @entity public class tabledetailsvo {     @id     // primary key of tabledetailsvo must database name      // , tablename databasename foriegn key databasedetailsvo     private string tablename;      @onetomany     private list<columndetailsvo>; }  public class columndetailsvo {     @id     // primary key of columndetailsvo must columnname     // databasename , tablename foriegn key tabledetailsvo     private string columnname;      private string columndatatype;     ... } 

how address using hibernate annotations? using hibernate 3.3.1 version.

@onetomany(fetch = fetchtype.lazy, mappedby = "databasedetailsvo") public set<tabledetailsvo> gettabledetailsvos() {     return this.stocktabledetailsvos; }
