Thank you Simon,
I have checked out the fixed sample and run a test.
I works! But I noticed that there's still some problems
with it: the node config composite generated by the
domain manager designates the service binding to be
multiple protocols(ws, jsonrpc, sca, and so on) by default.
And the "Add a node" page doesn't provide any fields to
configure the binding. If I want to specify the binding, I have
to manually edit the composite file.

Yes, that's a limitation of the domain manager UI. I'm willing
to live with the workaround of editing the files. If you'd like
to contribute some code to make it possible to change the binding
protocol settings from the UI, that would be very welcome.
And I also noticed that in tuscany 2.0, there is no such thing
as domain manager. So how do we manage a domain in
tuscany 2.0? I couldn't find anything in the documentation.
See [1] for a description.

Thank you Simon for your timely and useful help.
You're very welcome. The fix is now committed to the 1.x trunk.
To run the domain manager UI on this sample, you need to do the
following:
1. Check out the fixed sample from the 1.x trunk.
2. Build the sample
3. Open a command prompt and change directory to
samples/calculator-distributed
4. Launch the domain manager with a single argument
"target/classes". This
tells the domain manager where to look for its configuration
files. The
command I'm using to launch the domain manager is:
java -jar
../../modules/node-launcher/__target/tuscany-node-launcher-__1.7-SNAPSHOT.jar
domain target/classes
Before running this command, you need to set the TUSCANY_HOME
environment variable
to a directory containing the Tuscany binary distribution.

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.__ap__ache.org/cloud
<http://apache.org/cloud>
<http://tuscany.apache.org/__cloud
<http://tuscany.apache.org/cloud>>",
which should be xmlns:ns2="http://sample/__cloud__
<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
<http://tuscany.apache.org/__cloud>
<http://tuscany.apache.org/__cloud
<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.
