Cluster and commons-logging jar LogConfigurationException

Question

Hi,
My configuration:
-OAS 10.1.3.1 on 2 machines with oracle cluster configuration (discovery).
My app:
-ear which includes simple ejb3 module with commons-logging-1.1.jar lib (Jakarta commons logging)
-clustering and replication is configured (in orion-application.xml):
<cluster allow-colocation="false">
     <replication-policy trigger="onSetAttribute" scope="allAttributes" />
     <flow-control-policy enabled="false" />
     <protocol>
          <peer>
               <opmn-discovery />
          </peer>
     </protocol>
</cluster>
When I'm trying to deploy my application I always get an error during deployment:
[19-Jun-2007 16:46:44] Initializing ClassLoader(s)
[01-Jan-1970 01:00:00] Error deserializing return-value: org.apache.commons.logging.LogConfigurationException; nested exception is: java.lang.ClassNotFoundException: org.apache.commons.logging.LogConfigurationException
It doesn't matter if I try to deploy it on one or both machines. The exception is always the same on each machine.
When I get rid of clustering/replication configuration (from orion-application.xml or during deployment) application is deployed without any problem.
Also when I remove commons-logging-1.1.jar application is deployed.
I know that there is already apache.commons.logging 1.0.4 in OAS shared libraries by it's not selected in "Configure Class Loading" by default.
I also tried use the same version (1.0.4) in my app - didn't help.
I can also deploy without any problem war file or ear file with web module, which has commons-logging-1.1.jar. But not ejb!
Any advice?
Thanks

Hey Darek -- I just gave it a quick try -- the ListQueries query works as expected.
This is how I executed it and the results it returned.
