Well, I made a small amount of progress. I have at least proved that
ColdFusion can retrieve some kind of data from a National Weather Service web
service. But, it is not very useful yet. First of all, I played with the
code, and I was able to get a different error "Could not perform web service
invocation "NDFDgenByDay" because java.lang.IllegalArgumentException: argument
type mismatch". I have not been able to figure out what argument has a
mismatched type. But the code was now finding the service and its methods.
Then I found a different web service URI that I can get data from one of the
two functions to be returned. But this data is not properly formed XML. There
are several close tags "</someTag>" without an appropriate start tag. This
makes the data fairly difficult to use, I think.
I wanted to post my progress here, so that others interested with more web
service skill then I may be able to figure this out. I would really love to be
able to get data like this, because it could be a very nice addition to an
Outdoor Recreation site I maintain.
