OK, I understand the way remote nodes take part in the domain. It downloads the config info from the domain manager and run, right? So before the a node can run, we must add the node configuration in the cloud page. But I just cannot do it right. The "Add a node" form requires the following fields: Node name, (NodeE) Node URI, (http://localhost:8200) Composite namespace, (http://sample) Composite name, (CalculatorB) Contribution URI. (http://mycontrib) and that is all. I do some experiments with the calculator-distributed sample. I copy the NodeB folder in src/main/resources and NodeB.composite in src/main/resources/cloud into a new folder named "contrib" to E:\. Then I tried to add a node in the domain manager. I succeeded in adding a contribution and a composite but was stuck at the "Add a node" step. When I fill out the form and click "add". There is an new entry added in the list, but with the "Composite" column marked as "Problem: composite not found" and "Contribution" column marked as "unknown". I clicked on the newly added node and the URL is: http://localhost:9990/composite-source/composite:http://tuscany.apache.org/cloud;http://tuscany.apache.org/cloud;NodeE while the URL of a normal node is: http://localhost:9990/composite-source/composite:http://tuscany.apache.org/cloud;http://sample/cloud;NodeB
I think the problem may lie in XML namespace and the URL mapping of jetty http-server which is used in the domain manager. I tried to figure out what's wrong but I failed. And the documentation I could find is very limited. Thanks.
