CreateStoredProcedureQuery Is Not Resolved

here is my code and createStoredProcedureQuery has redline underneath in eclipse, and not resolved, I tried many ways still could not get what is wrong.

private static EntityManagerFactory factory;

public static void main(String[] args) {
    factory = Persistence.createEntityManagerFactory("mypersistenceUnit");
    EntityManager em = factory.createEntityManager();

    // Create call stored procedure
    em.getTransaction().begin();
    StoredProcedureQuery storedProcedure = em.**createStoredProcedureQuery**("getCode");
    // set parameters
    storedProcedure.registerStoredProcedureParameter("name", String.class, ParameterMode.IN);
    storedProcedure.registerStoredProcedureParameter("num", String.class, ParameterMode.IN);
    storedProcedure.registerStoredProcedureParameter("code", String.class, ParameterMode.OUT);

    // execute SP
    storedProcedure.execute();
    // get result
    String code= (String)storedProcedure.getOutputParameterValue("code");
    System.out.println("code is: " + code);
    em.getTransaction().commit();
    em.close();
}
