[Messaging, JMS & JBossMQ] - Re: Initial durable subscription setup
by npujol
Ok I am one step further as I found a way to make the association between the user and his connection thought I still have a problem with the message selector being nulled out. The trick is simply to make the association in the JMS_USERS tables by adding an entry in the mysql-jdbc-state-service.xml. So now that file looks like this:
<attribute name="SqlProperties">
| ....
| POPULATE.TABLES.01 = INSERT INTO JMS_USERS (USERID, PASSWD, CLIENTID) VALUES ('ds_user', 'changeit', '_ownsubscriber')
|
| POPULATE.TABLES.02 = INSERT INTO JMS_SUBSCRIPTIONS (CLIENTID, SUBNAME, TOPIC, SELECTOR) VALUES ("_ownsubscriber", "_emailSender0","IDMNotificationDurableTopic","subscribers like '%email%'")
| ....
| </attribute>
Note that for some reason the SELECTOR column does get cleared upon a call to
topicSession.createDurableSubscriber(topic,"_emailSend0");
Does anybody know why? I don't believe this is correct! thoughts?

[Messaging, JMS & JBossMQ] - Initial durable subscription setup
by npujol
Hi,
I was wondering if it was wrong to insert a row manually in theJMS_SUBSCRIPTIONS at table creation time in order to register a durable subscription? In my mysql-jdbc-state-service.xml:
<attribute name="SqlProperties">
| ....
| POPULATE.TABLES.01 = INSERT INTO JMS_SUBSCRIPTIONS (CLIENTID, SUBNAME, TOPIC, SELECTOR) VALUES ("_ownsubscriber", "_emailSender0","NotificationDurableTopic","subscribers like '%email%'")
| ....
| </attribute>
I think it is not - I am basically mimicing a managed topic just like it would be done in a jbossmq-state.xml with something like this:
| <DurableSubscription>
| <ClientID>_ownsubscriber</ClientID>
| <Name>_emailSender0</Name>
| <TopicName>NotificationDurableTopic</TopicName>
| <Selector>subscribers like '%email%'</Selector>
| </DurableSubscription>
It is my understanding that both ways of doing it basically relieve the JMS client code from having to specify the client id and subscription name on their durable subscriptions. In my environment it does seem to work though the jbossmq's client subscriber code
| topicSession.createDurableSubscriber(topic,"_emailSend0");
insists in adding a new row to JMS_SUBSCRIPTIONS and my JMS_SUBSCRIPTIONS table ends up looking like this:
| +----------------+---------------+-----------------------------+----------------------------+
| | CLIENTID | SUBNAME | TOPIC | SELECTOR |
| +----------------+---------------+-----------------------------+----------------------------+
| | _ownsubscriber | _emailSender0 | NotificationDurableTopic | subscribers like '%email%' |
| | ID:2 | _emailSender0 | NotificationDurableTopic | NULL |
| +----------------+---------------+-----------------------------+----------------------------+
|
It looks like I am missing a piece in my setup : I must associate the user with the connection as is done in jbossmq-state.xml by matching the User node with the durable subscription node. Does anybody know if it is even possible to create this association with a jboss-jdbc-state-service.xml DB setup? Thanks in advance

[JBoss Seam] - LIE with Seam-managed transactions
by spambob
Hello,
I somehow manage to get a LazyInitializationException when I use Seam-managed transactions.
What I want to do is retrieve an id from a request, load the usecase with said id and make it available to my jsf page - just like the dvd.xhtml in the dvd store example does for dvds.
When I use @Factory it works fine, but when I try to use page actions and @Out the usecase I get a LIE when it tries to access the first collection attribute (the application frame is generated with seam-gen and unmodified, I use Seam 1.1CR2 and JBoss AS 4.0.5).
My Bean:
@Stateful
| @Name("usecasesBean")
| public class UsecasesBean implements Usecases {
|
| @PersistenceContext
| private EntityManager em;
|
| @In(required=false, scope=ScopeType.EVENT)
| private String usecaseId;
|
| @Out(required = false)
| private Usecase usecase;
|
| @DataModel
| List<Usecase> usecases;
|
| @SuppressWarnings("unchecked")
| @Factory("usecases")
| public void findAllUsecases() {
| System.out.println("findAllUsecases...");
| System.out.println("usecaseId: " + usecaseId);
| usecases = (List<Usecase>) em.createQuery("Select u from Usecase u order by u.name").getResultList();
| }
|
| public void loadUsecaseById() {
| System.out.println("loadById...");
| if(usecaseId == null) {
| System.out.println("usecaseId was null");
| usecaseId = "1";
| }
| this.usecase = em.find(Usecase.class, Long.parseLong(usecaseId));
| System.out.println("Usecase: " + usecase.getName());
| }
|
| // @Factory("usecase")
| // public Usecase loadUsecaseById() {
| // System.out.println("loadById...");
| // if(usecaseId == null) {
| // System.out.println("usecaseId was null");
| // usecaseId = "1";
| // }
| // return em.find(Usecase.class, Long.parseLong(usecaseId));
| // }
| }
My pages.xml:<pages>
| <page view-id="/showUsecase.xhtml" action="#{usecasesBean.loadUsecaseById}" />
| </pages>
TransactionalSeamPhaseListener is loaded in faces-config.xml.
When I exchange the loadUsecaseById() methods, comment the @Out usecase out and remove the pages.xml this works fine but the way above I get the following exception:
01:35:21,631 INFO [STDOUT] findAllUsecases...

As you can see the page function is action is correctly called and the usecase is loaded from the db but I get a LIE when I access the first collection attribute (actors.) in my jsf.
Can someone please explain me why this happens.
Thanks a lot in advance.
