i have two tables

CREATE TABLE categories (
  categories_id BIGINT(20) NOT NULL,
  image VARCHAR(45) NOT NULL,
  parent_categories_id BIGINT(20) NOT NULL,
  sort_order INTEGER(3) NOT NULL,
  last_modified DATETIME NOT NULL,
  timestamp DATETIME NOT NULL,
  PRIMARY KEY(categories_id)

CREATE TABLE categories_lang (
  categories_id BIGINT(20) NOT NULL,
  languages_id BIGINT(20) NOT NULL,
  name VARCHAR(45) NOT NULL,
  description TEXT NOT NULL,
  PRIMARY KEY(categories_id, languages_id)

i created the ejb 3.0 -> all fine

but i don't know how i make i set or sth like this to get an specific categorieslang set when i ask for a special categorie?

what i have to add to categories ejb?

the categories lang should depend on the categories_id and the language id, which i have before ask for categories. actual i make another query to get the categories lang, but i want only one query where i get a categorie with a specific lang :-/

a have no solution found yet, because it is not an classic one...., connection...

thx stephan
