Hi, Hope someone can help me with this. I've created a simple echo service and exposed it as a web service component as follows:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"; targetNamespace="http://patient"; xmlns:pws="http://patient"; name="patient"> <component name="PatientServiceComponent"> <implementation.java class="patient.PatientServiceImpl"/> <service name="PatientService"> <interface.java interface="patient.PatientService"/> <binding.ws/> </service> </component> </composite> I can run it with an embedded scadomain, but when i invoke it as follows i get a NullPointerException: SCADomain scaDomain; scaDomain = SCADomain.newInstance("patient.composite"); PatientService patSvc = scaDomain.getService(PatientService.class, "PatientServiceComponent"); String result = patSvc.ping("hello world!"); System.out.println("result: " + result); System.in.read(); scaDomain.close(); The stack trace is as follow: Dec 19, 2007 12:15:52 AM org.apache.tuscany.sca.assembly.builder.impl.CompositeBuilderImpl$1 problem WARNING: [WARNING] Duplicate service name:
