[Installation, Configuration & Deployment] - SingleScheduleProvider and daylight savings?
by hale2jo
I have the following code which was hitting the target everyday at midnight.
| <mbean code="org.jboss.varia.scheduler.SingleScheduleProvider"
| name="jboss:service=HASingleScheduleProvider,name=SomeTarget">
| <depends>jboss:service=${jboss.partition.name:DefaultPartition}</depends>
| <depends>jboss:service=ScheduleManager</depends>
| <depends>abcd:name=SomeTarget</depends>
| <attribute name="PartitionName">${jboss.partition.name:DefaultPartition}</attribute>
| <attribute name="HASingleton">true</attribute>
| <attribute name="ScheduleManagerName">jboss:service=ScheduleManager</attribute>
|
| <attribute name="TargetName">abcd:name=SomeTarget</attribute>
| <attribute name="TargetMethod">hit( NOTIFICATION, DATE, REPETITIONS, SCHEDULER_NAME, java.lang.String )</attribute>
| <attribute name="StartDate">12/08/06 12:00 am</attribute>
| <attribute name="Period">86400000</attribute>
| <attribute name="Repetitions">-1</attribute>
| </mbean>
|
Now it is hitting the target everyday at 1am. I assume this is related to day light savings somehow. How do I get it to go back to going off at midnight without changing the time in StartDate to 11pm? Can I specify to ignore daylight savings somehow?
Thanks.

[Persistence, JBoss/CMP, Hibernate, Database] - CMR 2.1 and EJB-QL
by paoletto
hello. I have some errors trying to use ejb-ql 2.1 and i dont understand why :(
I am developing a test application to learn how to use j2ee ejbs
Im currently using EJB 2.1, so no 3.0.
what follows is what i tried following sun manuals and oreilly ejb 3rd edition book.
ok, so, let say i have a db with 2 tables: Dipartimento and Account such as
| CREATE TABLE DIPARTIMENTO (
| IdDipartimento INTEGER NOT NULL PRIMARY KEY,
| Descrizione VARCHAR(255),
| unique(Descrizione));
|
| CREATE TABLE ACCOUNT (
| Utente VARCHAR(32) NOT NULL PRIMARY KEY,
| Pwd VARCHAR(32) NOT NULL,
| Cognome VARCHAR(255) NOT NULL,
| Nome VARCHAR(255) NOT NULL,
| Ruolo VARCHAR(255) NOT NULL,
| Tipo INTEGER NOT NULL,
| Dipartimento INTEGER NOT NULL,
| foreign key(Dipartimento) references DIPARTIMENTO(IdDipartimento) on delete cascade on update cascade);
|
(obviously i dont create these tables with this SQL, since entity beans create for me)
now, i modelled these tables with CMP Entity bean, thus writing the beans (with all the getter and setter methods for the fields, the BeanNameCMP, the BeanNameLocal and BeanNameLocalHome interfaces), and put in the deployment descriptor correct entity blocks for them (i'll paste below).
Now, i would like to be able to perform JOIN queries with ejb-ql.
two sample queries i wanted to perform were:
| "SELECT OBJECT(a) FROM Account AS a WHERE a.Dipartimento.Descrizione = 'FOO'"
|
(select all the accounts with a certain department description) , and the sister query:
| "SELECT OBJECT(a) FROM Dipartimento d, IN (d.IdDipartimento) AS a WHERE d.Descrizione = 'FOO'"
|
this one was the first one, and is a bit strange, because i wanted to try this ejb-ql join, the IN operator.
ok. So afaiunderstood, i have to map these foreign key references as relations. so below is how i did it (i mapped the one to many relation between department and account in both way)

ok. Trying to deploy everything with this deployment descriptor results in this error (due to the query):
ERROR [Account#findRelatedAccounts] In path field is not a cmr field: at line 1, column 56. Encountered: "Dipartimento" after: "a."
If instead i try the second query (the one actually comented) i get:
00:17:15,944 ERROR [Account#findRelatedAccounts] Encountered "d.IdDipartimento" at line 1, column 48.
Was expecting:
<COLLECTION_VALUED_PATH> ...
that is more or less what i get if i try the first query using IN keyword, and not accessing directly a.Documento.Descrizione
what am i doing wrong? i mean this should not be something very complex to do, but i cant get it to work:(
thanks for any help!
below the code for one of the 2 beans (the other one is more or less the same):
| package servizioDipartimentale.ejb;
|
| import java.rmi.RemoteException;
|
| import javax.ejb.EJBException;
| import javax.ejb.EntityBean;
| import javax.ejb.EntityContext;
