That's odd, because I'm pretty sure SAA uses a later version - they support
SOAP services. They're pretty good about keeping on top of new technologies.
They even have their own internal web conference!

This isn't entirely a bad thing, although you should also be required to use
CFQUERYPARAM. CFQUERYPARAM won't help block XSS attacks.

Many agencies (and non-governmental organizations too, for that matter) have
long and complex requirements for software acceptance, so upgrades are slow.

All the form scrubbing may be a pain, but it's not a bad idea. That's
the stuff most people overlook.
We are in the title business and our public facing sites sanitize all
form and URL variables to make our customers happy about security.

Not using AT LEAST CF 7 is retardo though. I'm sure they probably have
a few miles of red tape in the way. I know the government supposedly
uses a lot of ColdFusion which is pretty cool.
I don't know if it's true, but I read once that Windows XP didn't have
any Easter eggs because the government used it and they couldn't use ANY
code with "undocumented features". Go figure.

Hmm - getting off topic - but the one Congressman site I've got - they
gave me a freaking FIT over using Coldfusion, and said that *only*
version 5 was "approved". I couldn't use anything else.
I had to put so much regex all over forms to block "bad" stuff and pass
their security scans that it was ridiculous.

Hmm - getting off topic - but the one Congressman site I've got - they
gave me a freaking FIT over using Coldfusion, and said that *only*
version 5 was "approved". I couldn't use anything else.
I had to put so much regex all over forms to block "bad" stuff and pass
their security scans that it was ridiculous.
Using "cfqueryparam", or any other Coldfusion validation/security didn't
matter at all - if there wasn't regx there to scrub *every* single
variable on the site, it wouldn't pass the scans and they wouldn't allow
the file to go live.
Isn't a fun client due to whomever is the server admin, believe me!!!
Maybe they were just p*ssed that somebody outside their regular circle
got to develop the site, I dunno...

You need to refresh the webservice stubs, not the CFC.
As people have said before, this is nothing to do with the CFC - it's
actually the client end of the webservice transaction that's doing the
caching.
<cfobject type="JAVA"
action="Create"
name="factory"
class="coldfusion.server.ServiceFactory">
<cfset RpcService = factory.XmlRpcService>
<cfset RpcService.refreshWebService("http://somesite/somecfc.cfc?wsdl")>
The above assumes you can't do it any of the better ways (admin API,
the CF8 way in one of the earlier posts, etc).

Even deleting the file - refreshing the page to throw and error, and
reloading the file again doesn't work. When these things get cached,
they freaking get
cached!!!

Thanks ...
Believe me - this isn't the worse development environment I've got either!
Anybody got a RSA SecurID generating numbers every 60 seconds for server
access? I've got four different ones - and they all look alike!
Anybody do any US government development? Like a congressman's website?
You wouldn't *believe* the security hurdles you've got to jump through
just to post a new version of a file to the server (all congressman
websites have to be on secure Whitehouse servers...ACK!)!
You can decide to take work or not - and so far the "difficult
development environment" folks I deal with also happen to have deep
pockets and don't mind reaching in as often as necessary for my extra
trouble. And believe me, I *charge* them well for the extra trouble!

I'd have an issue with anyone who forced such a setup on me. You might ask
them how you're expected to develop a solution when they can't or won't even
allow for a proper development flow. Basically it sounds like the decision
to work with an external system that limits your IP address to a single IP,
combined with the decision to develop on a server that you have no control
over, is turning out to be a pretty unacceptable combination.
Nic's solution is probably not going to do anything for you, because even
reloading the CFC instance that is the source of the web service isn't going
to cause CF itself to refresh the actual web service it has cached. If you
aren't on CF8 and able to use the refreshWSDL flag, and you also aren't able
to access the administrator to cycle the cached web service, then I'm afraid
you're out of options aside from manually recreating separate versions of
the target CFC every time you make a change.
And again, just to be clear to anyone else who might read the thread, the
problem has nothing to do with using CFCs at all. It's an issue with
ColdFusion's caching of all web services combined with a difficult
environment setup.

I believe refreshWSDL was added in CF8. For earlier version, this blog post
might help you.

Develop locally but if you want to force to refresh a webservice try
<cfset ws = createObject('webservice', someUrl, { refreshWSDL="yes" } )>

I know I can develop locally - but a several specific functions I'm
working on must come from a *specific* https address, or any incoming
cfhttp is rejected. This address is already defined and I don't have
access to change it, so I've no choice but to develop as much as I can
locally, and test from the actual server using the real address for the
submitting pages in question.
I think Nic has my solution though. Off to see what happens...

Besides deleting the web service from ColdFusion administrator, there is
some Admin API functionality that will do it programmatically but you
will obviously need the CF Admin password to use it.

It doesn't have anything to do with CFCs. ColdFusion has always cached web
services so it doesn't have to keep re-requesting and re-parsing the WSDL.
Please, do some research before you run out to a list and condemn something
that actually has nothing to do with your problem.
And as Barney said, doing development on a shared server is just silly when
you can (and should) be doing it locally.

In Application.cfc, just have an if statement that checks for the
existence of a url variable. if the url variable exists, call
onApplicationStart() and onSessionStart() explicitly. This will reload
all scoped CFCs.

If you have access to the CF Admin, turn off all of the template options for
your dev environment.

Boy I hate developing with CFCs..
Make an edit, test, make another edit - the darned thing doesn't
refresh. The only way I've found around this is to keep saving it under
a new name, and retest using the new name each time
<cfset request.cfcLOCATION="https://mysite.com/version1.cfc?wsdl">;
<cfset request.cfcLOCATION="https://mysite.com/version2.cfc?wsdl">;
<cfset request.cfcLOCATION="https://mysite.com/version3.cfc?wsdl">;
.... and so forth.
What a PITA!!
Is there any way (on a shared server that I've very little access to
beyond FTP) to *force* a CFC to refresh, or is this just the nature of
the beast?

Develop locally? There's a reason CF Enterprise is free for development.
