Re: How to pass a file to a web service.
Use the binary type when declaring the web service parameter for the
file content, have a separate parameter for the file name (if
necessary) and use the normal CF way to invoke the web service.
Theoretically you shouldn't get Out of Memory errors but I haven't
tested this...
ws.cfc
cffunction name=dataSubmit access=remote
cfargument name=file_name type=string
cfargument name=file type=binary
cfset fileWrite(arguments.file_name, arguments.file)
/cffunction
test.cfm
cfset ws = createObject(webservice, http://ws.cfc?wsdl;)
cfset ws.dataSubmit(ppur-test.xml, fileRead(expandPath('ppur-test.xml')))

How to pass a file to a web service.
What would be the web service equivalent of this HTTP request?

ppur_v0.cfc

cfargument name=ppurFile type=string required=yes hint=file
upload field

cfset var rootpath = getDirectoryFromPath(getCurrentTemplatePath())
cfset path =
replace(rootpath,htdocs/pur-loader/ws/,uploadedFiles/ppur/,ONE)
cffile action=upload filefield=ppurFile destination=#path#

cfset var validate = xmlValidate(cffile.serverDirectory '/'
cffile.serverFile,replace(rootpath,'/ws/','/schema/ppur-data-transmission.xsd','ONE'))

I.E. How would one pass a 'file' to a web service? Or can you only
pass the content of the file as a string? Which is differernt and
apparently does not work for what we are trying to do. When I did that,
we would start getting 'java heap out of memory' errors dealing with the
quanty of content we need to pass to this web service.
To clarify, is there a way to pass a file reference through a web
service object that can be used in a cffile action=upload... tag in
the cffunction... block?

Re: How to pass a file to a web service.
Ian, you would need to convert the uploaded file to base64 before
submitting it to the web service. This essentially will transfer the
file as text. Once the web service has it, you would then convert it
back to it's original binary format. Ben Nadel has an article
describing this process.

Re: How to pass a file to a web service.
If it is a file, then yes it is binary. The contents may be ASCII text, but the file itself is binary. When you convert the file to base64, you are converting it into a text string. This you can pass to the web service. The web service would then read the string, convert it back binary and use the cffile tag to save it.
