Two services in same category

[sanjoa]

Hello,

I'we defined one category 'CustomerServiceCategory', which contains two services 'AddressService' and 'CustomerService'. But JBoss ESB seems to map both services to the same service name:

[java] 21:21:26,734 DEBUG [main][RegistryUtil] Registering < CustomerService, EPR: PortReference < jms://queue > >

Although I'm selecting the correct service in the jms-bus:


<jms-provider name="JBossMQ"
connection-factory="ConnectionFactory"
jndi-context-factory="org.jnp.interfaces.NamingContextFactory"
jndi-URL="localhost">
<jms-bus busid="CustomerBus">
<jms-message-filter dest-type="QUEUE"
dest-name="queue/C" selector="service='CustomerService'" />
</jms-bus>
<jms-bus busid="AddressBus">
<jms-message-filter dest-type="QUEUE"
dest-name="queue/C" selector="service='AddressService'" />
</jms-bus>
</jms-provider>


So when I'm calling the CustomerService my call gets routed to the AddressService..




<jms-listener name="JMS-ESBListener"
busidref="CustomerBus" maxThreads="10" />





<jms-listener name="JMS-ESBListener"
busidref="AddressBus" maxThreads="10" />

Yes I'm sorry. This issue is listed under the "known issues" and is caused by the fact that classifications are not yet implemented by scout. It's on my TODO list, for the time being please use unique names for the category and service name.

Hi,

we are using the ESB 4.2.1 GA CP1 and gets a lot of ERROR messages according to below:

2009-05-12 09:23:54,510 ERROR [main] [org.jboss.internal.soa.esb.services.registry.JAXRRegistryImpl] Found 2 Services, while expecting only one by the name of <aServiceName> in category <aServiceCategory>

Is the known issue mentioned earlier in this thread is fixed in the version we are using or could our errors originate from the same problem?

Thanks in advance

You would need to provide us with more information I'm afraid, but there is a known issue with clustered registries and duplicates.

https://jira.jboss.org/jira/browse/JBESB-2444

Is there a reason you are still on 4.2.1CP1? There have been many changes to that branch and to trunk since that release.

Reviving this thread. We are on SOA-P 5.0.0 and having a similar issue. All our services now have unique category names, but still getting: "Found X Services, while expecting only one by the name of XXX in category ZZZ" when deploying to more than one node in a cluster.

It seems like the net effect of this issue is that we are unable to do any clustering of ESB services. Is that a fair assessment? If so, is there a known workaround? The jira is linked to SOA-2119 which looks to target SOA 5.1.0, if I am reading it right. Just trying to figure out our options, as we are targeted to be live in a few weeks.

TIA,

Mike

Mike, can you give a brief description of your cluster situation?      Also, have you tried dropping the jUDDI tables and having them recreate?       If you have done so, do you run into this situation frequently?

[mikefinn]

Hi Tom,

5 node SOA-P 5.0 cluster on RHEL. Oracle DB on the backend for messaging, juddi, etc.

With the workaround I posted to the 'JUDDI in cluster issue' thread ( http://community.jboss.org/thread/154140 ), this seems to have resolved itself. I am not sure why, but it must be related per your suggestion to drop/create the uddi tables.

Now able to farm ESB services (plus clustered queues/CFs) and achieve clustering of services.

Thanks,

Mike
