[jboss-jira] [JBoss JIRA] Commented: (JBAS-6013) Support createDestination in jboss/message-driven

Adrian Brock commented on JBAS-6013:
------------------------------------
This has been done.
The deployer can be found in deployers/ejb-deployer-jboss-beans.xml
(although it relates to ejb3 as well).
The deployer works by acting as a registry for
org.jboss.ejb.deployer.CreateDestination
beans that include a matcher and a factory.
The only current implementation is one that matches javax.jms.MessageListener and
jms-ra.rar
(i.e. a jms mdb using our resource adapter) and then creates a JBossMessaging
destination.
<!-- Deployer for automatically creating message driven destinations -->
<bean name="CreateDestinationDeployer"
class="org.jboss.ejb.deployers.CreateDestinationDeployer">
<incallback method="addCreateDestination"/>
<uncallback method="addCreateDestination"/>
</bean>
<!-- Destination creator for JBoss Messaging -->
<bean name="JBossMessageDestinationCreator"
class="org.jboss.ejb.deployers.CreateDestination">
<!-- We match any jms mdb that is going to be deployed using our rar -->
<property name="matcher">
<bean
class="org.jboss.ejb.deployers.SimpleCreateDestinationMatcher">
<property name="default">true</property>
<property
name="messageListener">javax.jms.MessageListener</property>
<property name="rarName">jms-ra.rar</property>
</bean>
</property>
<!-- Create a destination with JBoss Messaging -->
<property name="factory">
<bean
class="org.jboss.jms.server.destination.JBossMessagingCreateDestinationFactory">
<property
name="serverPeerName">jboss.messaging:service=ServerPeer</property>
<property
name="postOfficeName">jboss.messaging:service=PostOffice</property>
</bean>
</property>
</bean>
To enable the behaviour you need to add
<create-destination>true</create-destination>
on the <message-driven/> in your jboss.xml
Obviously anybody can add new CreateDestinations that do different things for
other rars or inbound types or the default matcher/factory can be changed
to alter when/how JBoss Messaging destinations
are created.
Support createDestination in jboss/message-driven

Key: JBAS-6013
URL: https://jira.jboss.org/jira/browse/JBAS-6013
Project: JBoss Application Server
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: EJB2, EJB3
Reporter: Adrian Brock
Assignee: Adrian Brock
Fix For: JBossAS-5.0.0.GA
In the old JMSContainerInvoker there was a flag called
"createJBossMQDestination"
which allowed the MDB to automatically create the JMS destination.
This has is no longer supported with the reworking of the metadata and changes to the MDB
container.
To re-introduce this behaviour and resolve some of the issues we had with this feature
(which lead
to it being disabled by default), the behaviour should be made pluggable via a deployer
instead.
Issues this will resolve over the previous implementation:
1) The Destination will be removed at undeployment
2) The Destination construction method can be replaced by switiching the deployer, e.g.
for different backend jms servers
including understanding rar specific activation config properties
3) The behaviour is not necessarily JMS specific, e.g. other inbound adapters could
create their own destinations
The legacy "createJBossMQDestination" will still be checked when it exists.
