I am running it as a webapp (with tomcat) I have the messages below in tomcat log. I can see it has a problem with the binding.ws... ( I bolded it)
How can I fix it? I used the part in the composite with a java application using tuscany 1.4 and it worked OK. I switched to yuscany 2.0 in the webapp, since I needed the web implementation. should I change something in the composite? 02/09/2009 16:59:52 org.apache.tuscany.sca.endpoint.impl.EndpointRegistryImpl addEndpointReference INFO: EndpointRegistry: Add endpoint reference - Endpoint Reference: URI = foo#reference(service) Target = Endpoint: URI = WebClientComponent#service(WebClientImpl) [Unresolved] 02/09/2009 17:00:53 org.apache.tuscany.sca.endpoint.impl.EndpointRegistryImpl addEndpointReference INFO: EndpointRegistry: Add endpoint reference - Endpoint Reference: URI = foo#reference(service) Target = Endpoint: URI = WebClientComponent#service(WebClientImpl) [Unresolved] 02/09/2009 17:00:54 org.apache.tuscany.sca.node.impl.NodeImpl start INFO: Starting node: http://tuscany.apache.org/sca/1.1/nodes/default 02/09/2009 17:00:54 org.apache.tuscany.sca.node.impl.NodeFactoryImpl configureNode INFO: Loading contribution: file:/C:/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/helloworld-jsp/WEB-INF/classes/ 02/09/2009 17:00:54 org.apache.tuscany.sca.contribution.processor.ExtensibleStAXArtifactProcessor read WARNING: Element { http://docs.oasis-open.org/ns/opencsa/sca/200903}binding.ws cannot be processed.
