Hi,
I'm a newbie trying to get messaging to work in the jboss 5 beta 4. Having some
problems which I tried to google-up and getting nowhere. Any hints from you folks are much
appreciated.
I modified destinations-service.xml to include my test queue definition.
| <mbean code="org.jboss.jms.server.destination.QueueService"
| name="jboss.messaging.destination:service=Queue,name=testQueue"
| xmbean-dd="xmdesc/Queue-xmbean.xml">
| <depends optional-attribute-name="ServerPeer">
| jboss.messaging:service=ServerPeer
| </depends>
| <depends>jboss.messaging:service=PostOffice</depends>
| <attribute name="SecurityConfig">
| <security>
| <role name="guest" read="true"
write="true"/>
| <role name="publisher" read="true"
write="true" create="false"/>
| <role name="noacc" read="false"
write="false" create="false"/>
| </security>
| </attribute>
| </mbean>
|
When I start jboss I see correctly that the queue is created:
| 13:59:48,548 INFO [QueueService] Queue[/queue/testQueue] started, fullSize=200000,
pageSize=2000, downCacheSize=2000
|
I used NetBeans 6.0.1 to create EJB app. I added an MDB using the wizard and connected to
to queue 'queue/testQueue'.
My jboss.xml is:
| <jboss>
| <enterprise-beans>
| <message-driven>
| <ejb-name>NewMessageBean</ejb-name>
| <jndi-name>NewMessageBean</jndi-name>
| <destination-jndi-name>queue/testQueue</destination-jndi-name>
| </message-driven>
| </enterprise-beans>
| </jboss>
|
the ejb-jar.xml is:
| <ejb-jar version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

| <ejb-name>NewMessageBean</ejb-name>
| <ejb-class>org.rex.NewMessageBean</ejb-class>
| <transaction-type>Container</transaction-type>
|
<message-destination-type>javax.jms.Queue</message-destination-type>

| <display-name>Destination for NewMessageMDB</display-name>

Looks like NetBeans is not yet compatible with jboss 5: you can't register servers
(domain drop-down ends up being empty) and so you can't do deployments from NetBeans.
So here is what I did to manually deploy my test app: I build the .jar and put it under
server/default/deploy and I see the server starting the deployment. I see the exception
shown below and that's where I am getting stuck:
exception: jndi-name not found as a child of message-driven

If I remove jndi-name element from jboss.xml (I added it after NetBeans MDB wizard), I get
following error during deployment:
|
jboss.j2ee:binding=message-driven-bean,jndiName=local/NewMessageBean@24490290,plugin=invoker,service=EJB
-> org.jboss.deployment.DeploymentException: The message-destination
'testQueue' has no jndi-name in jboss.xml
|
So it seems I'm providing wrong jndi-name which for some reason is a required param in
Jboss 5. Perhaps the jndi-name is correct but my NewMessageBean class is somenow not
compliant with something. I wonder if this has anything to do with differences between
JBoss MQ and Jboss Messaging. I suspect NetBeans generated the code and config files
targeted for JBoss MQ.
My MDB class head is:
public class NewMessageBean implements MessageDrivenBean, MessageListener { ...
I'm new to enterprise beans in general so I'm sorry if I'm missing something
obvious.
