This class was rewritten so that is only works with a local kernel.
Rewriting it for a local kernel vastly simplified the code and make
is more accessible for new users to help with the console, and it is
expected that the for the near future the console will always be
local. If you need these features from a remote client, I suggest
you first take a look at what is available via a standard remote JMX
connection. You can browse the MBeanServer using jconsole in Java5.
In the future, when we need a to access the kernel remotely for the
kernel, I expect us to use a remote pojo technology like
lingo.codehaus.org.

Hi Aron,
The code chunk from my first e-mail runs fine with G1.0 . Some of
the recent changes might have broken the KernelDelegate. I will
try to create a test client and post it to the dev-list.
Thanks,
Vamsi

Well, maybe I spoke too soon. After thinking more about it, I guess
there are two options:
1) Create your own GBean to run on the server side, where your client
gives simple commands and the GBean does all the work interfacing with
the server components, so that there's no serialization involved to
return a J2EEServer, etc.
2) It may be that it's not as hard as I'm imagining to convert GBean
arguments and return types to AbstractNames and vice versa in the
server and the proxies. Can you post a simple test client that gets
the servers from a domain or whatever and curently blows up? That
would make it easier to evaluate this kind of change.
Thanks,
Aaron
