As you know the register() method is removed from the AbstractTransportFactory in CXF 3.0. I found a problem , when CXF tries to create HTTPTransportFactory with default name space then it does not register the DestinationFactory in DestinationFactoryManager. So in CXFNonSpringServlet when DestinationFactory df = dfm .getDestinationFactory("http://cxf.apache.org/transports/http/configuration") is executed then it returns HttpTransportFactory with empty registry. The same registry is used by the servlet controller creation. Hence When I hit any URI then I get o/p as "Can't find the the request for" + request.getRequestURL() + "'s Observer. Please suggest me the solution or give me appropriate reply for the same.
