[jboss-user] [JCA/JBoss] - MDB with Oracle AQ via Sun Adapter

[ryandavid]

I have integrated Oracle AQ with JBoss 4.0.2 using the rar of Sun Adapter. I can send messages to a queue but I have some problems in using an MDB that reads from a queue.

The MDB is BMT because the adapater doesn't support XA connections.

I used this ejb-jar.xml

<ejb-jar>
  | <enterprise-beans>
  | 
  | 	<message-driven>
  | 		<ejb-name>TestJMSBean</ejb-name>
  | 		<ejb-class>it.senato.testjms.TestJMSBean</ejb-class>
  |         <messaging-type>javax.jms.MessageListener</messaging-type>        
  |         <transaction-type>Bean</transaction-type>
  | 
  |         <activation-config>
  |               <activation-config-property>
  |                  <activation-config-property-name>destinationType</activation-config-property-name>
  |                  <activation-config-property-value>javax.jms.Queue</activation-config-property-value>
  |               </activation-config-property>
  | 
  | 
  |             <activation-config-property>
  |                 <activation-config-property-name>destinationProperties</activation-config-property-name>
  |                 <activation-config-property-value>owner=senaprod,name=FROM_QUEUE</activation-config-property-value>
  |              </activation-config-property>
  |             <activation-config-property>
  |                 <activation-config-property-name>connectionFactoryProperties</activation-config-property-name>
  |                 <activation-config-property-value>jdbc_connect_string=jdbc:oracle:thin:scott/mypass at myhost:1521:svil,host=senadbmssvil,user=scott,password=mypass,port=1521,sid=svil,driver=thin</activation-config-property-value>
  |              </activation-config-property>
  | 
  |             <activation-config-property>
  |                 <activation-config-property-name>userName</activation-config-property-name>
  |                 <activation-config-property-value>scott</activation-config-property-value>
  |              </activation-config-property>
  |             <activation-config-property>
  |                 <activation-config-property-name>mypass</activation-config-property-name>
  |                 <activation-config-property-value>svil</activation-config-property-value>
  |              </activation-config-property>
  | 
  |            </activation-config>
  |            
  |     </message-driven>
  | 
  |   </enterprise-beans>
  | 
  |     <assembly-descriptor>
  |     </assembly-descriptor>
  | 
  | </ejb-jar>

this jboss.xml

<jboss>
  | 	<enterprise-beans>
  | 		
  | 	    <message-driven>
  |            <ejb-name>TestJMSBean</ejb-name>
  | 
  |             <invoker-bindings>
  |               <invoker>
  |                 <invoker-proxy-binding-name>message-inflow-driven-bean</invoker-proxy-binding-name>
  |               </invoker>
  |             </invoker-bindings>
  | 
  |             <resource-adapter-name>oracleaq.rar</resource-adapter-name>
  | 
  |        </message-driven>
  |     </enterprise-beans>
  | </jboss>
  | 

and finally this is the onMessage() method


  | 	public void onMessage(Message msg) {
  |         try {
  |             ctx.getUserTransaction().begin();
  | 
  |             logger.debug("onMessage...");
  |             // extract message
  |             TextMessage textMessage = null;
  |             try {
  |                 textMessage = (TextMessage) msg;
  | 
  |             } catch (ClassCastException ce) {
  |                 logger.warn("Received a non TextMessage");
  |                 ctx.getUserTransaction().commit();
  |                 return;
  |             }
  | 
  |             logger.info("Received a text message: " + textMessage.getText());
  |             msg.acknowledge();
  |             ctx.getUserTransaction().commit();
  | 
  |         } catch (NotSupportedException e) {
  |             logger.error(e.getMessage(),e);
  |         } catch (SystemException e) {
  |             logger.error(e.getMessage(),e);
  |         } catch (JMSException e) {
  | 			logger.error(e.getMessage(),e);
  |         } catch (RollbackException e) {
  |             logger.error(e.getMessage(),e);
  |         } catch (HeuristicMixedException e) {
  |             logger.error(e.getMessage(),e);
  |         } catch (HeuristicRollbackException e) {
  |             logger.error(e.getMessage(),e);
  |         }
  | 
  |     }
  | 

When I deploy this MDB, it reads the first message that's in the queue and prints out the text.
The other messages are deleted from the queue but their texts aren't printed out.
In addition the sender send's a message but nothing happens: no message in the queue and no printing out. 

It seems as the MDB is locking the queue.
