[jboss-user] [Clustering/JBoss] - How to run a Queue and MDB into a cluster
Hi all,
I need to migrate a queue and mdb into a cluster configuration.
I've read mutliple wiki and docs and I need some help.
I'm running all into a Jboss AS 4.05 Ga.
Actualy, to create queue, it is done directly by Jboss , in reading annotation from my
MDB. I haven't any xml files, all is done automaticly
For example, this is my annotation into my java file of mdb :
@MessageDriven(messageListenerInterface = MessageListener.class, activationConfig = {
| @ActivationConfigProperty(propertyName = "destinationType",
propertyValue = "javax.jms.Queue"),
| @ActivationConfigProperty(propertyName = "destination", propertyValue =
"queue/Cmd2MuQueue"),
| @ActivationConfigProperty(propertyName = "acknowledgeMode",
propertyValue = "Auto-acknowledge") })
|
Now, from what I've read, I understand that I've got to declare a queue and mdb
into xml file and to put it (with java class of MDB) into
JBOSS_HOME/deploy-hasingleton/jms.
I've made a conf file for queue, named myqueue-service.xml :
<mbean code="org.jboss.mq.server.jmx.Queue"
| name="jboss.mq.destination:service=Queue,name=Cmd2MuQueue">
| <depends
optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends>
| <depends
optional-attribute-name="SecurityManager">jboss.mq:service=SecurityManager</depends>
| <attribute name="SecurityConf">
| <security>
| <role name="guest" read="true" write="true"
create="true"/>
| </security>
| </attribute>
| <attribute name="ReceiversImpl">
| org.jboss.mq.server.ReceiversImplArrayList
| </attribute>
| </mbean>
|
And I've made a jar file contains :
| + com
| + society
| + CmdMessageDrivenBean.class
| + META-inf
| + ejb-jar.xml
| + jboss.xml
|
ejb-jar.xml :
<ejb-jar>
| <enterprise-beans>
| <message-driven>
| <description>Singleton MDB, MyMDB</description>
| <ejb-name>MyMDB</ejb-name>
| <ejb-class>com.society.CmdMessageDrivenBean</ejb-class>
| <transaction-type>Container</transaction-type>
| <acknowledge-mode>Auto-acknowledge</acknowledge-mode>
| <message-driven-destination>
| <destination-type>javax.jms.Queue</destination-type>
| </message-driven-destination>
| </message-driven>
| </enterprise-beans>
|
| <assembly-descriptor>
| <container-transaction>
| <method>
| <ejb-name>MyMDB</ejb-name>
| <method-name>onMessage</method-name>
| </method>
| <trans-attribute>Required</trans-attribute>
| </container-transaction>
| </assembly-descriptor>
|
| </ejb-jar>
and jboss.xml :
<jboss>
| <enterprise-beans>
| <message-driven>
| <ejb-name>MyMDB</ejb-name>
| <configuration-name>Singleton Message Driven
Bean</configuration-name>
|
<destination-jndi-name>queue/Cmd2MuQueue</destination-jndi-name>
| </message-driven>
| </enterprise-beans>
| </jboss>
First question : is it the right way ?
Second question : how I handle the fact that my mdb need to access to EJB3 classes , and
these classes aren't loaded yet, so I've got an class loading error, as my EJB3
ared loaded after queue actualy.. ??
Thanks a lot for ur responses.
