Query query = daoFactory
            .getEntityManager()
            .createQuery(
                    "SELECT a FROM Account a WHERE a.deleted=false AND a.type_id IN (SELECT id FROM "
                    + "AccountType WHERE deleted=false AND kind='BalanceSheet')");
List<Account> result = query.getResultList();

Answer 1

It looks like you forgot to give a identification variable to your AccountType entity.

SELECT a 
  FROM Account a 
 WHERE a.deleted=false 
   AND a.type_id IN (SELECT at.id FROM AccountType at
                      WHERE at.deleted=false 
                        AND at.kind= 'BalanceSheet')
