How to call firebird selectable stored procedure using JPA?

I'm trying to call a Firebird selectable procedure using JPA. The method looks like:

 public void addLineToBrokerReport(Map<String, Object> parametersForAddDealsProc) {

        MapUtils.debugPrint(System.out, "Parameters for procedure", parametersForAddDealsProc);

        String q = "select a.dol as id, a.out$error_code as error_code " +
            "from ADD_LINE (:IN$DOC," +
            ":IN$SHARE, " +
            ":IN$B_ACC, " +
            ":IN$S_ACC, " +
            ":IN$COMMENT) a";

      Query query = em.createNamedQuery(q, CallProcedureResult.class);
       for (Map.Entry<String, Object> entry : parametersForAddDealsProc.entrySet()) {
           query.setParameter("\"" + entry.getKey()+ "\"", entry.getValue());
        }
        CallProcedureResult result = (CallProcedureResult) query.getSingleResult();
        LOG.info("Error_code = " + result.getError_code()  + " dol = " + result.getId());

    }

After calling it is return the next error:

java.lang.IllegalArgumentException: Named query not found: select a.dol as id, a.out$error_code as error_code from P_TDA_ADD_LINE_TO_BROKER_REP (:IN$DOC,:IN$SHARE, :IN$B_ACC, :IN$S_ACC, :IN$COMMENT) a

Is it possible to call firebird select procedure using JPA?

Yes it is. You can use EntityManager#createNativeQuery instead.

Why "Named query not found" if there is Query query = em.createNamedQuery(q, CallProcedureResult.class); in method?

The first parameter of EntityManager#createNamedQuery must be a NamedQuery and it is not, it is an actual query in your case.

Unrelated to your problem, using named parameters in native queries is supported by Hibernate but it cannot be portably used across JPA implementations (https://stackoverflow.com/a/28829942/5078385).

em.createNamedQuery first argument is supposed to be the NAME of the NamedQuery (not the JPQL). The NamedQuery itself you would have defined in an annotation or XML, and specified the NAME against it. Also if you mean to invoke SQL direct (rather than JPQL), you need a NamedNativeQuery which is for a native query.

JPA 2.1 has support for Stored Procedures; whether that would work for invoking Firebird's things I've no idea, but you could try it also
