Description

Calling this method gives a NullPointerException. If I remove the serviceLocator.withCache(). Everything is working fine. I have attached my uddi.xml so that you can see my configuration.

private String resolveEndpointForServiceID(String uddiServiceId) {
        try {
            UDDIClient uddiClient = new UDDIClient();
            ServiceLocator serviceLocator = uddiClient.getServiceLocator("uddiv3");
            serviceLocator.setPolicy(PolicyRoundRobin.class.getName());
            serviceLocator.withCache(new URL("http","0.0.0.0",0, ""));
            return serviceLocator.lookupEndpoint(uddiServiceId);
        } catch (Exception e) {
            throw new EndpointResolutionFromUDDIException("Could not resolve endpoint '"+uddiServiceId+"'.", e);
        }
    }
