Re: [jgroups-dev] https://jira.jboss.org/browse/JGRP-1240

Where would the translation between the logical and physical normally happen? I ask because it seems odd that if we try again it works, I still think something might be going on.  If you don't mind I might take a look.  I just want to be sure there is no other way because this would complicate other things.  For example if we use sharedloopback on junit tests, there is no physical address to send, and thus I would need to complicate my code even more for cases like that.  I would really like to avoid this.  Thanks for your help so far!

I'm afraid adding a mapping between the logical address of P and its

work: this would have to be done at the level of the connection map, and 

this is not possible as we only know about physical addresses at the 

level of connection management.



So you have to add a header to your connection request which contains 

the logical address, physical address and logical name (if set). On the 

receiver side, you'll need to insert this information into the 

logical_addr_cache of TP, e.g. as follows (see also Discovery.up(), on 

reception of a discovery response):



Address addr; // UUID

String logical_name;

PhysicalAddress physical_addr;



down(new Event(Event.SET_PHYSICAL_ADDRESS, new 

Tuple<Address,PhysicalAddress>(addr, physical_addr));



if(logical_name != null)

   UUID.add((UUID)addr, logical_name);
