------------------------------------------------------------------
I have found the following *ugly* workaround to make it work.
{code}
private String resolveEndpointForServiceID(String uddiServiceId) {
try {
UDDIClient uddiClient = new UDDIClient();
// THIS UGLY LINE FIXES THE NullPointerException
FieldUtils.writeDeclaredField(uddiClient, "properties", new
Properties(), true);
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);
}
}
{code}
