In fact, I could not even add the node in the sample.
I delete a node for example NodeB, and then re-add it.
I got the same error as I was trying to add my remote node.
And I examined the cloud.composite in the root directory of
the domain manager. It turns out that the entry for NodeB has
some problems in xmlns:ns2. It is
xmlns:ns2="http://tuscany.apache.org/cloud";,
which should be xmlns:ns2="http://sample/cloud";.
So I think there maybe a bug in the "Add a node" page of domain manager
if I was right.
I've followed your instructions and I've been able to reproduce these
problems.
There is a bug, but it's not in the domain manager. The bug is in how
the calculator-distributed sample is set up. There are two problems:
1. The target namespace of the composites in the "cloud" directory should
be http://tuscany.apache.org/cloud, not http://sample.
2. The "cloud" directory should be directly underneath the directory
containing the workspace.xml and cloud.composite files.
These problems don't prevent the sample nodes from running, but they cause
errors when trying to work with this sample using the domain manager UI.
I will create a JIRA and fix these problems. If all goes well, the fix
should be committed later today.
Please also note that all the nodes in the cloud need to be defined in
a single "cloud" directory. The domain manager UI does this automatically
when you add a node to the cloud. This means that it isn't possible to
put one node's definition in a separate "cloud" directory under E:\contrib.
In contrast, the contribution directories can be placed anywhere.

Hi
IIRC when you have a domain containing remote nodes you have to start
all the nodes manually. You start then with the URL that describes the
node configuration at the domain managers and they will read their
configuration from that URL and start. For example, if you look at the
distributed calculator example [1] then you can see that it doesn't
use the domain manager GUI but does use the domain manager
configuration to allow remote nodes to take part in a distributed
domain.

Hope that helps
