is one of those arguments being passed as null? right above the cfinvoke
tag, I output all 3 of those variables and they all have values - they're NOT
null. is there some way about how I'm using the cfinvokeargument tag that's
wrong? how could I do this w/o cfinvokeargument...including the arguments in
the cfinvoke tag....? thanks.

They key to this is the error
org.xml.sax.SAXException: Error: URI=null Line=3: Illegal xml:lang value
''.

And this is a service side exception ("Server.userException") and it looks
like the service is generating the fault. So I believe that the request is
getting to the server OK, it is just that the server is throwing an error on
some XML, around line 3.

you're probably having trouble aressing that complex varable in the webservice.
CF really has a bad time with those. The problem is that a CF structure and a
CF array arent the correct datatypes to pass to the webservice. In some cases
you can massage them to get them to the right underlying java datatypes. But in
most cases we've had to wrte Java wrappers to teh webservice and then interface
with our local java. Its not a very nice solution especially given the Axis
version weirdness that comes w/ CFMX 7.

altimage,

Since the original poster is getting an XML parser error, he is not having
complex type problems with his service.

In any case, you can almost always create the correct CFML structure or
array which will get converted in to the right thing for a web service. For
some great info on this, check out this article:

I am not sure what you mean by "version weirdness" in CFMX 7. In order to
get document/literal and WS-I support (not to mention JAX-RPC 1.1) we needed
to update the version of Axis that we ship to Axis 1.2 (we actually ship
RC2+).

We expect to include the final 1.2 in whatever updater we ship in the future
for CFMX 7.

Hi Tom, Thanks for that link. I saw that article posted somewhere
yesterday...very helpful. Our experience has been that its very difficult
working with complex webservices. Im sure that linked article wil help get over
some of it a bt easier but in our case, we had to write a java wrapper to the
webservice and invoke that instead. The problem with the axis stuff really
hit us with version 7. There are 2 versions of the axis jars that ship with
cfmx 7 enterprise. We were moving over our webservice wrapper jar and it just
didnt work. It appeared that the jar was referencing a different version of
axis than what we were expecting and we had a really bad time trying to get it
to load the right one. It was like it would just ignore the load order we were
setting in our classpath and the jar would always fail even though the same
thing worked perfectly in 6.1. BTW Tom, if you have an extra couple minutes,
could you help me with this one.

how can I see the SOAP request it's sending? I'd like to see line 3 of the XML if I can....
