Hi again!
To start examining the different deployment options with SCA, I tried to
run the itest "two-nodes-two-vms-test".
I try to start a server and a client node in two separate JVMs on one
and the same computer.
Unfortunately, starting the client fails with the following exception:
Feb 22, 2010 9:17:50 PM
org.apache.tuscany.sca.core.runtime.impl.EndpointReferenceBinderImpl []
(EndpointReferenceCantBeMatched)
SEVERE: = Unable to match the endpoint reference
(@1162992854)EndpointReference: URI =
HelloworldClient#reference(service) WIRED_TARGET_NOT_FOUND Target =
(@24742184)Endpoint: URI = HelloworldService [Unresolved] with the
policy of the service to which it refers.

What could be the reason for something like this?
A second question related to the above mentioned test is where in the
SCA 1.1 specifications the format of the server-config.xml and
client-config.xml files, both with a <node> root element, are documented?
I am currently suspecting that some configuration in those files need
to be changed in order for the client node to be able to locate the
server node, for instance the domain="http://domain1"; attribute on the
<node> element.
Thanks!
Ivan
