Registry Service Tutorial 1 - Creating a Registry

In order to create a Registry we must first contact the Registry Service and try to call 'createRegistry' on it. First, define the location of the Registry Service.

private static String REGISTRY_SERVICE_ENDPOINT 
			= "https://hostname:port/gria-client-mgt/services/CltMgtRegistryService";

Then create a proxy to the Registry Service.

		
StateRepository repository = new MemoryStateRepository();
RemoteCltMgtRegistryService registryService = (RemoteCltMgtRegistryService)  
	repository.getOrCreateObject(RemoteCltMgtRegistryService.class,
			ConversationID.getEPR(REGISTRY_SERVICE_ENDPOINT));

Then try to call 'createRegistry' and print out the EPR

try {
	CltMgtRegistryResourceConversation reg = registryService.createRegistry("Registry 1");
	System.out.println("Created Registry '"+ConversationID.getLabel(reg.getEndpointRef())+"'"+"\n"+reg.getEndpointRef());
} catch (RemoteException e) {
	throw new RuntimeException(e);
} catch (ObjectAlreadyExists e){
	throw new RuntimeException(e);
}
