Brian Stansberry resolved JBAS-6284.
------------------------------------

    Resolution: Done


Fixed by passing the ProxyFactoryHA's ObjectName to the InvokerHA rather than the target service's ObjectName.

> I run in a JBoss cluster (my test involves here only 1 node in the default partition).
> I want to declare a HA proxy factory for my distributed service.
> Thus I add the following XML snippet in my service.xml file:
> <mbean code="org.jboss.proxy.generic.ProxyFactoryHA" name="the object name of my proxy factory">
>         <depends optional-attribute-name="InvokerName">jboss:service=invoker,type=jrmpha</depends>
>         <depends optional-attribute-name="TargetName">the object name of my target service</depends>
>         <attribute name="JndiName">my target service JNDI name</attribute>
>         <attribute name="InvokeTargetMethod">true</attribute>
>         <attribute name="ExportedInterfaces">the public interface of my target service</attribute>
>         <attribute name="ClientInterceptors">
>             <interceptors>
>                 <interceptor>org.jboss.proxy.ClientMethodInterceptor</interceptor>
>                 <interceptor>org.jboss.invocation.InvokerInterceptor</interceptor>
>             </interceptors>
>         </attribute>
>         <attribute name="PartitionObjectName">jboss:service=${jboss.partition.name:DefaultPartition}</attribute>
>         <attribute name="LoadBalancePolicy">org.jboss.ha.framework.interfaces.RoundRobin</attribute>
>     </mbean>
> When I invoke the proxy, I get the following stack trace :
> java.lang.IllegalArgumentException: null object name

>         ......
> I made the exact same test using the "normal" (i.e. not cluster-aware) version of the proxy factory : in the service.xml file,
> I changed the code attribute of the bean to "org.jboss.invocation.jrmp.server.JRMPProxyFactory",
> I changed the name of the invoker to "jboss:service=invoker,type=jrmp", and
> I removed the two attributes dedicated to the clustered version (PartitionObjectName and LoadBalancePolicy).
> The invocation of my public remote method raised no error.
> Thus there are two cases : either I miss something in the XML declaration of the HA proxy factory, or there is a bug in the underlying implementation.
> Thanks for your help.
