RE: [eclipselink-users] RMI Cache Coordination Exceptions 
Hello Tony,
   Can you verify that you are _manually_ starting a registry service on the machine with IP 10.0.0.116 at port 8881 ?  EclipseLink will not start a registry for you.

I am still getting the same error with this - I have just installed
Milestone 2 and rebuilt and the same issues occur:

Hello Tony,
    The URL configured for cache coordination should point to the
location where this system should register its listener using IP or
resolvable system name _not_ localhost.  'localhost' is seen in a lot of
examples but only works when all running systems are on the same
hardware.
    With RMI Cache Coordination the topology you choose for the
registries is up to you but generally the recommended approach is to
start a registry on each system.  Having to specify the IP of the local
machine in each system's config can be painful so EclipseLink offers a
special URL format that will cause EclipseLink to autodetect the local
IP of this system.  Change 'cm.setUrl("rmi://localhost:8881");' to
'cm.setUrl("rmi://$HOST:8881");'
    Alternatively you could have a single registry hosted on a single
system and have all of your systems point to that registry requiring you
to specify only one URL.

    The second thing to know is that there has been a bug fix in the
cache coordination code.  During the migration the RMI stubs that had
existed in the original EclipseLink code were renamed but not
regenerated.  These stubs were incorrect and would result in an
Unmarshal exception.  That has now been fixed and the changes will be in
Milestone 2 due out tonight.

Upgrading to the new milestone download and changing the url to use the
$HOST token should resolve you coordination problems.

Tony,

I believe I am now seeing the same or at least very similar exception in
my test case. I will walk through it with the developers on Monday and
see if we can get to the bottom of things. Hopefully this is just a
minor issue that we can quickly patch for you.

Doug

I'm still getting exceptions trying to get RMI coordinated caching to
work.  It makes the DB call ok but about 4-5 seconds after it blows up
as below:
